    Soichi Ando; Nana Ogoh; Shotaro Saito; Hironori Watanabe; Maki Ohsuga; Tetsuya Hasegawa; Shigehiko Ogoh
    Translational Sports Medicine, Hindawi Limited, 2023巻, 掲載ページ 1-5, 出版日 2023年11月02日, 査読付, Recently, there has been a growing focus on studies related to women’s football. However, the cognitive function of female football players has not been extensively characterized. Thus, we explored how the cognitive function of female football players was altered during a series of matches in summer and examined day-to-day variations in cognitive function with regard to dehydration status. Resting cognitive function was assessed from 17 young women football players during the Japan Club Youth Women’s football tournament, which spanned eight consecutive days. Cognitive function initially improved, with this improvement sustained throughout the tournament. It is worth noting that ten participants experienced symptoms of dehydration at least once during the tournament; however, these symptoms were not found to be linked to impaired cognitive function, suggesting that resting cognitive function remains unaffected during summer matches, even in the presence of dehydration symptoms.

  • Acute hypoxia impairs posterior cerebral bioenergetics and memory in man
    Ando S; Tsukamoto H; Stacey BS; Washio T; Owens TS; Calverley TA; Fall L; Marley CJ; Iannetelli A; Hashimoto T; Ogoh S; Bailey DM
    Exp Physiol, 出版日 2023年10月, 査読付, 国際誌, Hypoxia has the potential to impair cognitive function; however, it is still uncertain which cognitive domains are adversely affected. We examined the effects of acute hypoxia (∼7 h) on central executive (Go/No-Go) and non-executive (memory) tasks and the extent to which impairment was potentially related to regional cerebral blood flow and oxygen delivery (CDO2 ). Twelve male participants performed cognitive tasks following 0, 2, 4 and 6 h of passive exposure to both normoxia and hypoxia (12% O2 ), in a randomized block cross-over single-blinded design. Middle cerebral artery (MCA) and posterior cerebral artery (PCA) blood velocities and corresponding CDO2 were determined using bilateral transcranial Doppler ultrasound. In hypoxia, MCA DO2 was reduced during the Go/No-Go task (P = 0.010 vs. normoxia, main effect), and PCA DO2 was attenuated during memorization (P = 0.005 vs. normoxia) and recall components (P = 0.002 vs. normoxia) in the memory task. The accuracy of the memory task was also impaired in hypoxia (P = 0.049 vs. normoxia). In contrast, hypoxia failed to alter reaction time (P = 0.19 vs. normoxia) or accuracy (P = 0.20 vs. normoxia) during the Go/No-Go task, indicating that selective attention and response inhibition were preserved. Hypoxia did not affect cerebral blood flow or corresponding CDO2 responses to cognitive activity (P > 0.05 vs. normoxia). Collectively, these findings highlight the differential sensitivity of cognitive domains, with memory being selectively vulnerable in hypoxia. NEW FINDINGS: What is the central question of this study? We sought to examine the effects of acute hypoxia on central executive (selective attention and response inhibition) and non-executive (memory) performance and the extent to which impairments are potentially related to reductions in regional cerebral blood flow and oxygen delivery. What is the main finding and its importance? Memory was impaired in acute hypoxia, and this was accompanied by a selective reduction in posterior cerebral artery oxygen delivery. In contrast, selective attention and response inhibition remained well preserved. These findings suggest that memory is selectively vulnerable to hypoxia.

  • The effects of environmental enrichment on voluntary physical activity and muscle mass gain in growing rats
    Mizuki Sudo; Yutaka Kano; Soichi Ando
    Frontiers in Physiology, Frontiers Media SA, 14巻, 出版日 2023年09月28日, 査読付, Introduction: Environmental enrichment (EE) for rodents involves housing conditions that facilitate enhanced sensory, cognitive, and motor stimulation relative to standard housing conditions. A recent study suggested that EE induces muscle hypertrophy. However, it remains unclear whether muscle hypertrophy in EE is associated with voluntary physical activity, and the characteristics of muscle adaptation to EE remain unclarified. Therefore, this study investigated whether muscle adaptation to EE is associated with voluntary physical activity, and assessed the changes in the muscle fiber-type distribution and fiber-type-specific cross-sectional area in response to EE.

    Methods: Wistar rats (6 weeks of age) were randomly assigned to either the standard environment group (n = 10) or the EE group (n = 10). The voluntary physical activity of rats housed in EE conditions was measured using a recently developed three-axis accelerometer. After exposure to the standard or enriched environment for 30 days, the tibialis anterior, extensor digitorum longus, soleus, plantaris, and gastrocnemius muscles were removed and weighed. Immunohistochemistry analysis was performed on the surface (anterior) and deep (posterior) areas of the tibialis anterior and soleus muscles.

    Results and discussion: The EE group showed increased voluntary physical activity during the dark period compared with the standard environment group (p = 0.005). EE induced muscle mass gain in the soleus muscle (p = 0.002) and increased the slow-twitch muscle fiber cross-sectional area of the soleus muscle (p = 0.025). EE also increased the distribution of high-oxidative type IIa fibers of the surface area (p = 0.001) and type I fibers of the deep area (p = 0.037) of the tibialis anterior muscle. These findings suggest that EE is an effective approach to induce slow-twitch muscle fiber hypertrophy through increased daily voluntary physical activity.

    Journal of sport and health science, 出版日 2023年05月04日, 査読付, 国際誌, BACKGROUND: There is a growing interest to understand the neurobiological mechanisms that drive the positive associations of physical activity and fitness with measures of cognitive performance. To better understand those mechanisms, several studies have employed eye-based measures (e.g., eye movement measures such as saccades, pupillary measures such as pupil dilation, and vascular measures such as retinal vessel diameter) deemed to be proxies for specific neurobiological mechanisms. However, there is currently no systematic review providing a comprehensive overview of these studies in the field of exercise-cognition science. Thus, this review aims to address that gap in the literature. METHODS: To identify eligible studies, we searched 5 electronic databases on October 23rd 2022. Two researchers independently extracted data and assessed the risk of bias using a modified version of the Tool for the assEssment of Study qualiTy and reporting in EXercise (TESTEX scale, for interventional studies) and the critical appraisal tool from the Joanna Briggs Institute (for cross-sectional studies). RESULTS: Our systematic review (n = 35 studies) offers the following main findings: (a) there is insufficient evidence available to draw solid conclusions concerning gaze-fixation-based measures, (b) the evidence that pupillometric measures, which are a proxy for the noradrenergic system, can explain the positive effect of acute exercise and cardiorespiratory fitness on cognitive performance is mixed, (c) physical training- or fitness-related changes of the cerebrovascular system (operationalized via changes in retinal vasculature) are, in general, positively associated with cognitive performance improvements, (d) acute and chronic physical exercises show a positive effect based on an oculomotor-based measure of executive function (operationalized via antisaccade tasks), and (e) the positive association between cardiorespiratory fitness and cognitive performance is partly mediated by the dopaminergic system (operationalized via spontaneous eye-blink rate). CONCLUSION: This systematic review offers confirmation that eye-based measures can provide valuable insight into the neurobiological mechanisms that may drive positive associations between physical activity and fitness and measures of cognitive performance. However, due to the limited number of studies utilizing specific methods for obtaining eye-based measures (e.g., pupillometry, retinal vessel analysis, spontaneous eye blink rate) or investigating a possible dose-response relationship, further research is necessary before more nuanced conclusions can be drawn. Given that eye-based measures are economical and non-invasive, we hope this review will foster the future application of eye-based measures in the field of exercise-cognition science.

  • Effects of Three-Dimension Movie Visual Fatigue on Cognitive Performance and Brain Activity.
    Akagi R; Sato H; Hirayama T; Hirata K; Kokubu M; Ando S
    Front Hum Neurosci, 16巻, 974406号, 掲載ページ 974406-974406, 出版日 2022年10月, 査読付, 国際誌, To further develop three-dimensional (3D) applications, it is important to elucidate the negative effects of 3D applications on the human body and mind. Thus, this study investigated differences in the effects of visual fatigue on cognition and brain activity using visual and auditory tasks induced by watching a 1-h movie in two dimensions (2D) and 3D. Eighteen young men participated in this study. Two conditions were randomly performed for each participant on different days, namely, watching the 1-h movie on television in 2D (control condition) and 3D (3D condition). Before and after watching the 1-h movie on television, critical flicker fusion frequency (CFF: an index of visual fatigue), and response accuracy and reaction time for the cognitive tasks were determined. Brain activity during the cognitive tasks was evaluated using a multi-channel near-infrared spectroscopy system. In contrast to the control condition, the decreased CFF, and the lengthened reaction time and the decreased activity around the right primary somatosensory cortex during Go/NoGo blocks in the visual task at post-viewing in the 3D condition were significant, with significant repeated measures correlations among them. Meanwhile, in the auditory task, the changes in cognitive performance and brain activity during the Go/NoGo blocks were not significant in the 3D condition. These results suggest that the failure or delay in the transmission of visual information to the primary somatosensory cortex due to visual fatigue induced by watching a 3D movie reduced the brain activity around the primary somatosensory cortex, resulting in poor cognitive performance for the visual task. This suggests that performing tasks that require visual information, such as running in the dark or driving a car, immediately after using a 3D application, may create unexpected risks in our lives. Thus, the findings of this study will help outlining precautions for the use of 3D applications.

  • The effects of acute high intensity aerobic exercise on cognitive performance: a structured narrative review.
    Sudo M; Costello JT; McMorris T; Ando S
    Front Behav Neurosci, 16巻, 957677号, 掲載ページ 957677-957677, 出版日 2022年09月, 査読付, 国際誌, It is well established that acute moderate-intensity exercise improves cognitive performance. However, the effects of acute high-intensity aerobic exercise on cognitive performance have not been well characterized. In this review, we summarize the literature investigating the exercise-cognition interaction, especially focusing on high-intensity aerobic exercise. We discuss methodological and physiological factors that potentially mediate cognitive performance in response to high-intensity exercise. We propose that the effects of high-intensity exercise on cognitive performance are primarily affected by the timing of cognitive task (during vs. after exercise, and the time delay after exercise). In particular, cognitive performance is more likely to be impaired during high-intensity exercise when both cognitive and physiological demands are high and completed simultaneously (i.e., the dual-task paradigm). The effects may also be affected by the type of cognitive task, physical fitness, exercise mode/duration, and age. Second, we suggest that interactions between changes in regional cerebral blood flow (CBF), cerebral oxygenation, cerebral metabolism, neuromodulation by neurotransmitters/neurotrophic factors, and a variety of psychological factors are promising candidates that determine cognitive performance in response to acute high-intensity exercise. The present review has implications for recreational, sporting, and occupational activities where high cognitive and physiological demands are required to be completed concurrently.

  • Cognitive improvement after aerobic and resistance exercise is not associated with peripheral biomarkers.
    Ando S; Komiyama T; Tanoue Y; Sudo M; Costello JT; Uehara Y; Higaki Y
    Front Behav Neurosci, 16巻, 853150号, 掲載ページ 853150-853150, 出版日 2022年03月, 査読付, 国際誌, The role of peripheral biomarkers following acute physical exercise on cognitive improvement has not been systematically evaluated. This study aimed to explore the role of peripheral circulating biomarkers in executive performance following acute aerobic and resistance exercise. Nineteen healthy males completed a central executive (Go/No-Go) task before and after 30-min of perceived intensity matched aerobic and resistance exercise. In the aerobic condition, the participants cycled an ergometer at 40% peak oxygen uptake. In the resistance condition, they performed resistance exercise using elastic bands. Before and after an acute bout of physical exercise, venous samples were collected for the assessment of following biomarkers: adrenaline, noradrenaline, glucose, lactate, cortisol, insulin-like growth hormone factor 1, and brain-derived neurotrophic factor. Reaction time decreased following both aerobic exercise and resistance exercise (p = 0.04). Repeated measures correlation analysis indicated that changes in reaction time were not associated with the peripheral biomarkers (all p > 0.05). Accuracy tended to decrease in the resistance exercise condition (p = 0.054). Accuracy was associated with changes in adrenaline [r rm (18) = -0.51, p = 0.023], noradrenaline [r rm (18) = -0.66, p = 0.002], lactate [r rm (18) = -0.47, p = 0.035], and brain-derived neurotrophic factor [r rm (17) = -0.47, p = 0.044] in the resistance condition. These findings suggest that these peripheral biomarkers do not directly contribute to reduction in reaction time following aerobic or resistance exercise. However, greater sympathoexcitation, reflected by greater increase in noradrenaline, may be associated with a tendency for a reduction in accuracy after acute resistance exercise.

  • Effects of electrical muscle stimulation on cerebral blood flow
    Ando S; Takagi Y; Watanabe H; Mochizuki K; Sudo M; Fujibayashi M; Tsurugano S; Sato K
    BMC Neurosci, 22巻, 67号, 掲載ページ 67-67, 出版日 2021年11月, 査読付, 国際誌, BACKGROUND: Electrical muscle stimulation (EMS) induces involuntary muscle contraction. Several studies have suggested that EMS has the potential to be an alternative method of voluntary exercise; however, its effects on cerebral blood flow (CBF) when applied to large lower limb muscles are poorly understood. Thus, the purpose of this study was to examine the effects of EMS on CBF, focusing on whether the effects differ between the internal carotid (ICA) and vertebral (VA) arteries. METHODS: The participants performed the experiments under EMS and control (rest) conditions in a randomized crossover design. The ICA and VA blood flow were measured before and during EMS or control. Heart rate, blood pressure, minute ventilation, oxygen uptake, and end-tidal partial pressure of carbon dioxide (PETCO2) were monitored and measured as well. RESULTS: The ICA blood flow increased during EMS [Pre: 330 ± 69 mL min-1; EMS: 371 ± 81 mL min-1, P = 0.001, effect size (Cohen's d) = 0.55]. In contrast, the VA blood flow did not change during EMS (Pre: 125 ± 47 mL min-1; EMS: 130 ± 45 mL min-1, P = 0.26, effect size = 0.12). In the EMS condition, there was a significant positive linear correlation between ΔPETCO2 and ΔICA blood flow (R = 0.74, P = 0.02). No relationships were observed between ΔPETCO2 and ΔVA blood flow (linear: R = - 0.17, P = 0.66; quadratic: R = 0.43, P = 0.55). CONCLUSIONS: The present results indicate that EMS increased ICA blood flow but not VA blood flow, suggesting that the effects of EMS on cerebral perfusion differ between anterior and posterior cerebral circulation, primarily due to the differences in cerebrovascular response to CO2.

  • Effects of alterations in visual flow on psychophysiological responses to virtual reality exercise.
    Yasukawa K; Koike Y; Konno T; Sudo M; Ohkawara K; Ando S
    Percept Mot Skills, 128巻, 3号, 掲載ページ 1169-1182, 出版日 2021年06月, 査読付, 国際誌, Virtual reality (VR) technology combined with exercise, called VR exercise, is believed to have beneficial effects on mood; but VR factors contributing to improved mood remain ambiguous. The purpose of this study was to examine the effect of visual flow speed on psychophysiological responses (i.e., physiological responses, ratings of perceived exertion or RPE, and mood) to immersive VR exercise in a simulated natural environment. Eighteen male participants (Mage =23.1, SD = 1.9 years) cycled an ergometer at 80 watts for 5 minutes on three separate occasions while watching a first-person VR movie through VR goggles at three different speeds of visual flow, corresponding to 7.5 km.h-1, 15 km.h-1, and 22.5 km.h-1. The order of the three speeds was randomized in a counterbalanced design. We measured heart rate, oxygen uptake, minute ventilation, respiratory rate, and cadence during the exercise, and we recorded ratings of perceived exertion (RPE) and mood immediately after the exercise. We evaluated mood states with the Two-Dimensional Mood Scale. One-way repeated measures analysis of variance or the Friedman test revealed no significant effects on any physiological variables, RPE or cadence as a result of altered visual flow speed during VR exercise (p > .05). However, speed of visual flow significantly influenced participant ratings of Vitality (p = 0.01) and Pleasure (p = 0.02), with the faster speed resulting in a more positive mood state. As these findings showed that VR exercise with faster visual flow induced positive mood states, we recommend faster visual flow to induce better mood states in VR exercise.

  • Effects of acute interval handgrip exercise on cognitive performance.
    Washio T; Suzuki K; Saito S; Watanabe H; Ando S; Brothers RM; Ogoh S
    Physiol Behav, 232巻, 掲載ページ 113327-113327, 出版日 2021年04月, 査読付, 国際誌, Previous studies have reported that even a single bout of dynamic exercise improves cognitive performance. However, the acute effect of the interval handgrip (HG) exercise protocol, which is effective in reducing resting blood pressure, on cognitive performance is poorly understood. Cognitive performance was assessed in 17 young healthy subjects before and after a resting control (e.g., time control) and the interval HG exercise (Exercise), which consisted of four trials of 2-min HG exercise at 25% of maximum voluntary contraction with 3-min recovery in between each trial. Mean arterial blood pressure (MAP) and middle cerebral artery blood velocity (MCA V) were measured continuously throughout the experiment. Memory recognition and executive function were assessed using memory recognition and Go/No-Go tasks, respectively. During interval HG exercise, MAP and mean MCA V increased from the resting baseline condition (both P < 0.049) and returned to the resting baseline levels during recovery after the interval HG exercise (both P = 1.000). The reaction time and performance accuracy of the memory recognition task did not change in either the time control condition or Exercise condition (P = 0.514 and P = 0.414 respectively). However, the changes in reaction time of Go/No-Go task from the baseline in Exercise condition was significantly shorter than that in time-control condition (P = 0.004) without affecting performance accuracy (P = 0.482). The results of the present study show that an acute interval HG exercise could improve the processing speed in executive function despite no post-exercise improvement in hemodynamic parameters in young healthy subjects. These findings suggest that the interval HG exercise is a useful exercise mode that can be expected to have a positive effect on the processing speed in executive function regardless of cardiovascular adaptation to exercise.

  • Effect of intermittent isometric handgrip exercise protocol with short exercise duration on cognitive performance.
    Saito S; Washio T; Watanabe H; Ando S; Ogoh S
    J Physiol Sci, 71巻, 1号, 掲載ページ 12-12, 出版日 2021年04月, 査読付, 国内誌, The handgrip exercise, a small muscle exercise, is useful for exercise therapy, particularly in the elderly and bedridden patients. The isometric handgrip (IHG) exercise has been utilized in training programs to reduce resting blood pressure; however, the acute effects of the IHG exercise on cognitive performance are not fully understood. The present study aimed to investigate the effect of an intermittent IHG exercise protocol with short exercise duration, which minimizes the arterial blood pressure response to exercise, on cognitive performance. Twenty-two young healthy subjects performed the intermittent IHG exercise protocol, which consisted of 30-s IHG and 45-s recovery × 16 trials; the exercise intensity of the IHG exercise was 30% of the maximal voluntary contraction. Cognitive performance was evaluated before and after the exercise with the Go/No-Go and memory recognition tasks. Specifically, the reaction time (RT) and performance accuracy were measured. The intermittent IHG exercise protocol did not change the RT or performance accuracy of either the Go/No-Go task (P = 0.222 and P = 0.260, respectively) or the memory recognition task (P = 0.427 and P = 0.245, respectively). These findings suggest that the intermittent IHG exercise protocol with short exercise duration may not provide enough stimulation to improve cognitive performance despite being useful as a safe exercise therapy in the elderly and in patients with cardiovascular disease.

  • Plasma brain-derived neurotrophic factor and dynamic cerebral autoregulation in acute response to glycemic control following breakfast in young men.
    Tsukamoto H; Ishibashi A; Marley CJ; Shinohara Y; Ando S; Bailey DM; Hashimoto T; Ogoh S
    Am J Physiol Regul Integr Comp Physiol, 320巻, 1号, 掲載ページ R69-R79, 出版日 2021年01月, 査読付, 国際誌, We examined the acute impact of both low- and high-glycemic index (GI) breakfasts on plasma brain-derived neurotrophic factor (BDNF) and dynamic cerebral autoregulation (dCA) compared with breakfast omission. Ten healthy men (age 24 ± 1 yr) performed three trials in a randomized crossover order; omission and Low-GI (GI = 40) and High-GI (GI = 71) breakfast conditions. Middle cerebral artery velocity (transcranial Doppler ultrasonography) and arterial pressure (finger photoplethysmography) were continuously measured for 5 min before and 120 min following breakfast consumption to determine dCA using transfer function analysis. After these measurements of dCA, venous blood samples for the assessment of plasma BDNF were obtained. Moreover, blood glucose was measured before breakfast and every 30 min thereafter. The area under the curve of 2 h postprandial blood glucose in the High-GI trial was higher than the Low-GI trial (P < 0.01). The GI of the breakfast did not affect BDNF. In addition, both very-low (VLF) and low-frequency (LF) transfer function phase or gains were not changed during the omission trial. In contrast, LF gain (High-GI P < 0.05) and normalized gain (Low-GI P < 0.05) were decreased by both GI trials, while a decrease in VLF phase was observed in only the High-GI trial (P < 0.05). These findings indicate that breakfast consumption augmented dCA in the LF range but High-GI breakfast attenuated cerebral blood flow regulation against slow change (i.e., the VLF range) in arterial pressure. Thus we propose that breakfast and glycemic control may be an important strategy to optimize cerebrovascular health.

  • Cognitive impairment during high-intensity exercise: influence of cerebral blood flow.
    Komiyama T; Tanoue Y; Sudo M; Costello JT; Uehara Y; Higaki Y; Ando S
    Med Sci Sports Exerc, 52巻, 3号, 掲載ページ 561-568, 出版日 2020年03月, 査読付, 国際誌, PURPOSE: Cognitive performance appears to be impaired during high-intensity exercise, and this occurs concurrently with a reduction in cerebral blood flow (CBF). However, it is unclear whether cognitive impairment during high-intensity exercise is associated with reduced CBF. We tested the hypothesis that a reduction in CBF is responsible for impaired cognitive performance during high-intensity exercise. METHODS: Using a randomized crossover design 17 healthy males performed spatial delayed response and Go/No-Go tasks in three conditions (exercise [EX], exercise+CO2 [EX+CO2], and a nonexercising control [CON]). In the EX and EX+CO2, they performed cognitive tasks at rest and during 8 min of moderate and high-intensity exercise. Exercise intensity corresponded to ~50% (moderate) and ~80% (high) of peak oxygen uptake. In the EX+CO2, the participants inspired hypercapnic gas (2% CO2) during high-intensity exercise. In the CON, they performed the cognitive tasks without exercise. RESULTS: Middle cerebral artery mean velocity increased during high-intensity exercise in the EX+CO2 relative to the EX (69.4 [10.6] cm·s, vs 57.2 [7.7] cm·s, P < 0.001). Accuracy of the cognitive tasks was impaired during high-intensity exercise in the EX (84.1% [13.3%], P < 0.05) and the EX+ CO2 (85.7 [11.6%], P < 0.05) relative to rest (EX: 95.1% [5.3%], EX+CO2: 95.1 [5.3%]). However, no differences between the EX and the EX+CO2 were observed (P > 0.10). These results demonstrate that restored CBF did not prevent cognitive impairment during high-intensity exercise. CONCLUSIONS: We conclude that a reduction in CBF is not responsible for impaired cognitive performance during high-intensity exercise.

  • The interactive effects of acute exercise and hypoxia on cognitive performance: a narrative review.
    Ando S; Komiyama T; Sudo M; Higaki Y; Ishida K; Costello, JT; Katayama K
    Scand J Med Sci Sports, 30巻, 3号, 掲載ページ 384-398, 出版日 2020年03月, 査読付, 国際誌, Acute moderate intensity exercise has been shown to improve cognitive performance. In contrast, hypoxia is believed to impair cognitive performance. The detrimental effects of hypoxia on cognitive performance are primarily dependent on the severity and duration of exposure. In this review, we describe how acute exercise under hypoxia alters cognitive performance, and propose that the combined effects of acute exercise and hypoxia on cognitive performance are mainly determined by interaction among exercise intensity and duration, the severity of hypoxia, and duration of exposure to hypoxia. We discuss the physiological mechanism(s) of the interaction and suggest that alterations in neurotransmitter function, cerebral blood flow, and possibly cerebral metabolism are the primary candidates that determine cognitive performance when acute exercise is combined with hypoxia. Furthermore, acclimatization appears to counteract impaired cognitive performance during prolonged exposure to hypoxia although the precise physiological mechanism(s) responsible for this amelioration remain to be elucidated. This review has implications for sporting, occupational, and recreational activities at terrestrial high altitude where cognitive performance is essential. Further studies are required to understand physiological mechanisms that determine cognitive performance when acute exercise is performed in hypoxia.

    J Physiol, 597巻, 21号, 掲載ページ 5145-5159, 出版日 2019年11月, 査読付, 国際誌, KEY POINTS: DNA methylation may play an important role in regulating gene expression in skeletal muscle to adapt to physical activity and inactivity. Neuronal nitric oxide synthase (nNOS) in skeletal muscle is a key regulator of skeletal muscle mass; however, it is unclear whether nNOS expression is regulated by DNA methylation. We found that 1 week of cast immobilization increased nNOS DNA methylation levels and downregulated nNOS gene expression in atrophic slow-twitch soleus muscle from the mouse leg. These changes were not detected in non-atrophic fast-twitch extensor digitorum longus muscle. Twelve hours of cast immobilization decreased nNOS gene expression, whereas nNOS DNA methylation levels were unchanged, suggesting that downregulation of nNOS gene expression by short-term muscle inactivity is independent of the DNA methylation pattern. These findings contribute to a better understanding of the maintenance of skeletal muscle mass and prevention of muscle atrophy by epigenetic mechanisms via the nNOS/NO pathway. ABSTRACT: DNA methylation is a mechanism that controls gene expression in skeletal muscle under various environmental stimuli, such as physical activity and inactivity. Neuronal nitric oxide synthase (nNOS) regulates muscle atrophy in skeletal muscle. However, the mechanisms regulating nNOS expression in atrophic muscle remain unclear. We hypothesized that nNOS expression in atrophic muscle is regulated by DNA methylation of the nNOS promotor in soleus (Sol; slow-twitch fibre dominant) and extensor digitorum longus (EDL; fast-twitch fibre dominant) muscles. One week of cast immobilization induced significant muscle atrophy in Sol but not in EDL. We showed that 1 week of cast immobilization increased nNOS DNA methylation levels in Sol, although only a minor change was detected in EDL. Consistent with the increased DNA methylation levels in atrophic Sol, the gene expression levels of total nNOS and nNOSµ (i.e. the major splicing variant of nNOS in skeletal muscle) decreased. The abundance of the nNOS protein and cell membrane (especially type IIa fibre) immunoreactivity also decreased in atrophic Sol. These changes were not observed in EDL after 1 week of cast immobilization. Furthermore, despite the lack of significant atrophy, 12 h of cast immobilization decreased gene expression levels of total nNOS and nNOSµ in Sol. However, no association was detected between nNOS DNA methylation and gene expression. The expression of the nNOSβ gene, another splicing variant of nNOS, in EDL was unchanged by cast immobilization, whereas its expression was not detected in Sol. We concluded that chronic adaptation of nNOS gene expression in cast immobilized muscle may involve nNOS DNA methylation.

  • Fixating at far distance shortens reaction time to peripheral visual stimuli at specific locations
    Masahiro Kokubu; Soichi Ando; Shingo Oda
    Neuroscience Letters, Elsevier Ireland Ltd, 664巻, 掲載ページ 15-19, 出版日 2018年01月18日, 査読付, The purpose of the present study was to examine whether the fixation distance in real three-dimensional space affects manual reaction time to peripheral visual stimuli. Light-emitting diodes were used for presenting a fixation point and four peripheral visual stimuli. The visual stimuli were located at a distance of 45 cm and at 25° in the left, right, upper, and lower directions from the sagittal axis including the fixation point. Near (30 cm), Middle (45 cm), Far (90 cm), and Very Far (300 cm) fixation distance conditions were used. When one of the four visual stimuli was randomly illuminated, the participants released a button as quickly as possible. Results showed that overall peripheral reaction time decreased as the fixation distance increased. The significant interaction between fixation distance and stimulus location indicated that the effect of fixation distance on reaction time was observed at the left, right, and upper locations but not at the lower location. These results suggest that fixating at far distance would contribute to faster reaction and that the effect is specific to locations in the peripheral visual field. The present findings are discussed in terms of viewer-centered representation, the focus of attention in depth, and visual field asymmetry related to neurological and psychological aspects.

  • Cognitive function during exercise under severe hypoxia

    SCIENTIFIC REPORTS, NATURE PUBLISHING GROUP, 7巻, 1号, 掲載ページ 10000, 出版日 2017年08月, 査読付, Acute exercise has been demonstrated to improve cognitive function. In contrast, severe hypoxia can impair cognitive function. Hence, cognitive function during exercise under severe hypoxia may be determined by the balance between the beneficial effects of exercise and the detrimental effects of severe hypoxia. However, the physiological factors that determine cognitive function during exercise under hypoxia remain unclear. Here, we examined the combined effects of acute exercise and severe hypoxia on cognitive function and identified physiological factors that determine cognitive function during exercise under severe hypoxia. The participants completed cognitive tasks at rest and during moderate exercise under either normoxic or severe hypoxic conditions. Peripheral oxygen saturation, cerebral oxygenation, and middle cerebral artery velocity were continuously monitored. Cerebral oxygen delivery was calculated as the product of estimated arterial oxygen content and cerebral blood flow. On average, cognitive performance improved during exercise under both normoxia and hypoxia, without sacrificing accuracy. However, under hypoxia, cognitive improvements were attenuated for individuals exhibiting a greater decrease in peripheral oxygen saturation. Cognitive performance was not associated with other physiological parameters. Taken together, the present results suggest that arterial desaturation attenuates cognitive improvements during exercise under hypoxia.

This study clarified the effects of repeated BFR, ECC, and BFR combined with ECC (BFR+ECC) on muscle fiber hypertrophy.
    MethodsMale Wistar rats were assigned to 3 groups: BFR, ECC, and BFR+ECC. The contralateral leg in the BFR group served as a control (CONT). Muscle fiber cross-sectional area (CSA) of the tibialis anterior was determined after the respective treatments for 6 weeks.
    ResultsCSA was greater in the BFR+ECC group than in the CONT (P<0.01) and ECC (P<0.05) groups. CSA was greater in the BFR group than that in the CONT group (P<0.05).
    CnclusionsThese results suggest that repeated BFR alone as well as BFR+ECC induces muscle fiber hypertrophy at the cellular level. Muscle Nerve55: 274-276, 2017

    BIOCHEMICAL AND BIOPHYSICAL RESEARCH COMMUNICATIONS, ACADEMIC PRESS INC ELSEVIER SCIENCE, 476巻, 4号, 掲載ページ 635-640, 出版日 2016年08月, 査読付, Previous studies have shown that an enriched environment (EE) has an important effect on brain function via the neuronal nitric oxide synthase/nitric oxide (nNOS/NO) pathway in young and aged animals. However, whether EE induces its effect by altering nNOS expression levels and whether it lowers anxiety-like behaviors in aged mice remains unclear. Here, we show that nNOS expression levels increased with age in the hippocampus and cerebellum in aged mice, but not in the cortex. Moreover, EE reduced anxiety-like behaviors in aged mice and reduced nNOS expression levels in the cerebellum, but not in the cortex. The present study suggests that EE improves anxiety-like behaviors in aged mice by altering nNOS expression levels in the hippocampus or cerebellum. (C) 2016 Elsevier Inc. All rights reserved.

  • Slowed response to peripheral visual stimuli during strenuous exercise
    Soichi Ando; Takaaki Komiyama; Masahiro Kokubu; Mizuki Sudo; Akira Kiyonaga; Hiroaki Tanaka; Yasuki Higaki
    PHYSIOLOGY & BEHAVIOR, PERGAMON-ELSEVIER SCIENCE LTD, 161巻, 掲載ページ 33-37, 出版日 2016年07月, 査読付, Recently, we proposed that strenuous exercise impairs peripheral visual perception because visual responses to peripheral visual stimuli were slowed during strenuous exercise. However, this proposal was challenged because strenuous exercise is also likely to affect the brain network underlying motor responses. The purpose of the current study was to resolve this issue. Fourteen participants performed a visual reaction-time (RT) task at rest and while exercising at 50% (moderate) and 75% (strenuous) peak oxygen uptake. Visual stimuli were randomly presented at different distances from fixation in two task conditions: the Central condition (2 degrees or 5 degrees from fixation) and the Peripheral condition (30 degrees or 50 degrees from fixation). We defined premotor time as the time between stimulus onset and the motor response, as determined using electromyographic recordings. In the Central condition, premotor time did not change during moderate (167 +/- 19 ms) and strenuous (168 +/- 24 ms) exercise from that at rest (164 +/- 17 ms). In the Peripheral condition, premotor time significantly increased during moderate (181 +/- 18 ms, P < 0.05) and strenuous exercise (189 +/- 23 ms, P < 0.001) from that at rest (173 +/- 17 ms). These results suggest that increases in Premotor Time to the peripheral visual stimuli did not result from an impaired motor-response network, but rather from impaired peripheral visual perception. We conclude that slowed response to peripheral visual stimuli during strenuous exercise primarily results from impaired visual perception of the periphery. (C) 2016 Elsevier Inc. All rights reserved.

  • Cognitive function at rest and during exercise following breakfast omission
    Takaaki Komiyama; Mizuki Sudo; Naoki Okuda; Tetsuhiko Yasuno; Akira Kiyonaga; Hiroaki Tanaka; Yasuki Higaki; Soichi Ando
    PHYSIOLOGY & BEHAVIOR, PERGAMON-ELSEVIER SCIENCE LTD, 157巻, 掲載ページ 178-184, 出版日 2016年04月, 査読付, It has been suggested that breakfast omission, as opposed to breakfast consumption, has the detrimental effects on cognitive function. However, the effects of acute exercise following breakfast omission on cognitive function are poorly understood, particularly during exercise. The purpose of this study was to examine the interactive effects of breakfast and exercise on cognitive function. Ten participants completed cognitive tasks at rest and during exercise in the breakfast consumption or omission conditions. Blood glucose concentration was measured immediately after each cognitive task. We used cognitive tasks to assess working memory [Spatial Delayed Response (DR) task] and executive function [Go/No-Go (GNG) task]. The participants cycled ergometer for 30 min while keeping their heart rate at 140 beats.min(-1). Accuracy of the GNG task was lower at rest in the breakfast omission condition than that in the breakfast consumption condition (Go trial: P = 0.012; No-Go trial: P = 0.028). However, exercise improved accuracy of the Go trial in the breakfast omission condition (P = 0.013). Reaction time in the Go trial decreased during exercise relative to rest in both conditions (P = 0.002), and the degree of decreases in reaction time was not different between conditions (P = 0.448). Exercise and breakfast did not affect the accuracy of the Spatial DR task. The present results indicate that breakfast omission impairs executive function, but acute exercise improved executive function even after breakfast omission. It appears that beneficial effects of acute exercise on cognitive function are intact following breakfast omission. (C) 2016 Elsevier Inc. All rights reserved.

  • 身体不活動者を対象としたストレッチ運動が気分と認知機能に及ぼす影響.
    須藤みず紀; 安藤創一; 永松俊哉
    体力研究, 公益財団法人 明治安田厚生事業団 体力医学研究所, 114巻, 掲載ページ 11-19, 出版日 2016年04月, 査読付, Chronic physical inactivity has a potential to induce negative affective states and impair cognitive function. In
    contrast, it has been suggested that exercise at moderate intensity improves affective states and cognitive function.
    Nevertheless, moderate exercise may induce stress responses in those who are physically inactive, which implies that moderate exercise may not be appropriate to improve affective states and cognitive function for the inactive population.
    Stretching is a common form in general fitness, and may reduce anxiety and improve affective states. Hence, we
    expected that acute stretching is beneficial to affective states and cognitive function, particularly in inactive people.
    However, it is unclear how stretching alters affective states and cognitive function in inactive people. The purpose of this study was to examine the effects of acute stretching on affective states and cognitive function in inactive people.
    Nineteen subjects participated in the present study. They performed a cognitive task(Trail Making Test: TMT)
    and answered questionnaires(Mood Check List-short form 2: MCL-S.2 and WASEDA)before and after stretching
    or rest (control)for 10 min. The order of stretching and control was counter-balanced. MCL-S.2 was used to assess
    pleasantness, relaxation, and anxiety, and WASEDA was used to assess negative affect, positive engagement, and
    tranquility. Saliva levels of immunoglobulin A(IgA)were measured before and after stretching or rest.
    Reaction time in the TMT significantly decreased after stretching. Pleasantness and positive engagement increased after stretching. These alterations were not observed in the control condition. Stretching did not affect
    salivary IgA. These results suggest that improvements in cognitive performance may be associated with positive
    affective states induced by acute stretching. In conclusion, the present results suggest that stretching improves affective states and cognitive function in inactive people.

  • Effects of acute static stretching on visual search performance and mood state
    Mizuki Sudo; Soichi Ando; Toshiya Nagamatsu
    Journal of Physical Education and Sport, Editura Universitatii din Pitesti, 15巻, 4号, 掲載ページ 651-656, 出版日 2015年12月01日, 査読付, Static stretching appears to not only enhance flexibility, but also to improve mood state. However, little is known about how acute static stretching influences cognitive function. To elucidate this, we tested the hypothesis that alterations in mood state following static stretching would improve visual search performance. Sixteen participants were divided into stretching and control groups. In the stretching group, the participants answered questionnaires about mood state and performed a visual search task before and after 30 min of static stretching. In the control group, the participants rested instead of stretching. The questionnaires included items related to pleasantness, relaxation, anxiety, negative affect, positive engagement, and tranquility. We evaluated changes in cerebral hemodynamics and oxygenation during the visual search task via near-infrared spectroscopy. In the stretching group, reaction time in the visual search task decreased (P <
    0.05), while response accuracy was not affected. This improvement in response speed was accompanied by increase in positive engagement (P <
    0.01) and a decrease in anxiety (P <
    0.05). Stretching did not modulate cerebral hemodynamics or oxygenation during the visual search task. Visual search performance was not altered in the control group. These results suggest that improved response speed is associated with an increase in positive engagement and a decrease in anxiety after static stretching.

  • The effects of temporal neck cooking on cognitive function during strenuous exercise in a hot environment: A pilot study
    Soichi Ando; Takaaki Komiyama; Mizuki Sudo; Akira Kiyonaga; Hiroaki Tanaka; Yasuki Higaki
    BMC Research Notes, BioMed Central Ltd., 8巻, 1号, 出版日 2015年05月30日, 査読付, Background: Heat stress potentially has detrimental effects on brain function. Hence, cognitive function may be impaired during physical activity in a hot environment. Skin cooling is often applied in a hot environment to counteract heat stress. However, it is unclear to what extent neck cooling is effective for cognitive impairment during exercise in a hot environment. The purpose of this study was to examine the effects of temporal neck cooling on cognitive function during strenuous exercise in a hot environment. Methods: Eight male young participants (mean ± SD, age = 26.1 ± 3.2 years
    peak oxygen uptake = 45.6 ± 5.2 ml/kg/min) performed Spatial delayed response (DR) task (working memory) and Go/No-Go task (executive function) at rest and during exercise in the Hot and Hot + Cooling conditions. After the participants completed the cognitive tasks at rest, they cycled the ergometer until their heart rate (HR) reached 160 beats/min. Then, they cycled for 10 min while keeping their HR at 160 beats/min. The cognitive tasks were performed 3 min after their HR reached 160 beats/min. The air temperature was maintained at 35°C and the relative humidity was controlled at 70%. Neck cooling was applied to the backside of the neck by a wet towel and fanning. We used accuracy of the Spatial DR and Go/No-Go tasks and reaction time in the Go/No-Go task to assess cognitive function. Results: Neck cooling temporarily decreased the skin temperature during exercise. The accuracy of the cognitive tasks was lower during exercise than that at rest in the Hot and Hot + Cooling condition (p <
    0.05). There were no differences in the accuracy between the Hot and Hot + Cooling conditions (p = 0.98). Neither exercise (p = 0.40) nor cooling (p = 0.86) affected reaction time. These results indicate that temporal neck cooling did not alter cognitive function during strenuous exercise in a hot environment. Conclusions: The present study suggests that temporal neck cooling with a wet towel and fanning is not effective for attenuating impairment of working memory and executive function during strenuous exercise with a short duration in a warm and humid environment.

  • Does moderate hypoxia alter working memory and executive function during prolonged exercise?
    Takaaki Komiyama; Mizuki Sudo; Yasuki Higaki; Akira Kiyonaga; Hiroaki Tanaka; Soichi Ando
    PHYSIOLOGY & BEHAVIOR, PERGAMON-ELSEVIER SCIENCE LTD, 139巻, 掲載ページ 290-296, 出版日 2015年02月, 査読付, It has been suggested that acute exercise improves cognitive function. However, little is known about how exercise under hypoxia affects cognitive function. The purpose of this study was to determine if hypoxia alters working memory and executive function during prolonged exercise. Sixteen participants performed cognitive tasks at rest and during exercise under normoxia and hypoxia [fraction of inspired oxygen (FIO2) = 0.15, corresponding to an altitude of approximately 2600 m]. The level of hypoxia was moderate. We used a combination of Spatial Delayed Response (Spatial DR) task and Go/No-Go (GNG) task, where spatial working memory and executive function are required. Working memory was assessed by the accuracy of the Spatial DR task, and executive function was assessed by the accuracy and reaction time in the GNG task. The participants cycled an ergometer for 30 min under normoxia and moderate hypoxia while keeping their heart rate (HR) at 140 beats/min. They performed the cognitive tasks 5 mm. 23 mm after their HR reached 140 beats/min. Moderate hypoxia did not alter the accuracy of the Spatial DR (P = 0.38) and GNG tasks (P = 0.14). In contrast, reaction time in the GNG task significantly decreased during exercise relative to rest under normoxia and moderate hypoxia (P = 0.02). These results suggest that moderate hypoxia and resultant biological processes did not provide sufficient stress to impair working memory and executive function during prolonged exercise. The beneficial effects on speed of response appear to persist during prolonged exercise under moderate hypoxia. (c) 2014 Elsevier Inc All rights reserved.

  • Blood flow restriction prevents muscle damage but not protein synthesis signaling following eccentric contractions
    Mizuki Sudo; Soichi Ando; David C. Poole; Yutaka Kano
    Physiological Reports, American Physiological Society, 3巻, 7号, 出版日 2015年, 査読付, There is a growing body of evidence to suggest that resistance training exercise combined with blood flow restriction (BFR) increases muscle size and strength in humans. Eccentric contraction (ECC) frequently induces severe muscle damage. However, it is not known whether and to what extent muscle damage occurs following ECC + BFR due to the difficulty of conducting definitive invasive studies. The purpose of this study was to examine muscle fiber damage following ECC + BFR at the cellular level. High-intensity ECC was purposefully selected to maximize the opportunity for muscle damage and hypertrophic signaling in our novel in vivo animal model. Male Wistar rats were assigned randomly to the following groups: ECC and ECC + BFR at varying levels of occlusion pressure (140, 160, and 200 Torr). In all conditions, electrical stimulation was applied to the dorsiflexor muscles simultaneously with electromotor- induced plantar flexion. We observed severe histochemical muscle fiber damage (area of damaged fibers/total fiber area analyzed) following ECC (26.4 � 4.0%). Surprisingly, however, muscle damage was negligible following ECC + BFR140 (2.6 � 1.2%), ECC+BFR160 (3.0 � 0.5%), and ECC + BFR200 (0.2 � 0.1%). Ribosomal S6 kinase 1 (S6K1) phosphorylation, a downstream target of rapamycin (mTOR)-phosphorylation kinase, increased following ECC + BFR200 as well as ECC. In contrast, S6K1 phosphorylation was not altered by BFR alone. The present findings suggest that ECC combined with BFR, even at high exercise intensities, may enhance muscle protein synthesis without appreciable muscle fiber damage.

    BIOCHEMICAL AND BIOPHYSICAL RESEARCH COMMUNICATIONS, ACADEMIC PRESS INC ELSEVIER SCIENCE, 448巻, 2号, 掲載ページ 175-181, 出版日 2014年05月, 査読付, Introduction: Carnitine palmitoyltransferase II (CPT II) deficiency is an inherited disorder involving beta-oxidation of long-chain fatty acids (FAO), which leads to rhabdomyolysis and subsequent acute renal failure. The detailed mechanisms of disease pathogenesis remain unknown; however, the availability of relevant human cell types for investigation, such as skeletal muscle cells, is limited, and the development of novel disease models is required.
    Methods: We generated human induced pluripotent stem cells (hiPSCs) from skin fibroblasts of a Japanese patient with CPT II deficiency. Mature myocytes were differentiated from the patient-derived hiPSCs by introducing myogenic differentiation 1 (MYOD1), the master transcriptional regulator of myocyte differentiation. Using an in vitro acylcarnitine profiling assay, we investigated the effects of a hypolipidemic drug, bezafibrate, and heat stress on mitochondrial FAO in CPT II-deficient myocytes and controls.
    Results: CPT II-deficient myocytes accumulated more palmitoylcarnitine (C16) than did control myocytes. Heat stress, induced by incubation at 38 degrees C, leads to a robust increase of C16 in CPT II-deficient myocytes, but not in controls. Bezafibrate reduced the amount of C16 in control and CPT II-deficient myocytes.
    Discussion: In this study, we induced differentiation of CPT II-deficient hiPSCs into mature myocytes in a highly efficient and reproducible manner and recapitulated some aspects of the disease phenotypes of CPT II deficiency in the myocyte disease models. This approach addresses the challenges of modeling the abnormality of FAO in CPT II deficiency using iPSC technology and has the potential to revolutionize translational research in this field.

  • The Effects of Exercise Under Hypoxia on Cognitive Function
    Soichi Ando; Yoichi Hatamoto; Mizuki Sudo; Akira Kiyonaga; Hiroaki Tanaka; Yasuki Higaki
    PLoS ONE, 8巻, 5号, 出版日 2013年05月10日, 査読付, Increasing evidence suggests that cognitive function improves during a single bout of moderate exercise. In contrast, exercise under hypoxia may compromise the availability of oxygen. Given that brain function and tissue integrity are dependent on a continuous and sufficient oxygen supply, exercise under hypoxia may impair cognitive function. However, it remains unclear how exercise under hypoxia affects cognitive function. The purpose of this study was to examine the effects of exercise under different levels of hypoxia on cognitive function. Twelve participants performed a cognitive task at rest and during exercise at various fractions of inspired oxygen (FIO2: 0.209, 0.18, and 0.15). Exercise intensity corresponded to 60% of peak oxygen uptake under normoxia. The participants performed a Go/No-Go task requiring executive control. Cognitive function was evaluated using the speed of response (reaction time) and response accuracy. We monitored pulse oximetric saturation (SpO2) and cerebral oxygenation to assess oxygen availability. SpO2 and cerebral oxygenation progressively decreased during exercise as the FIO2 level decreased. Nevertheless, the reaction time in the Go-trial significantly decreased during moderate exercise. Hypoxia did not affect reaction time. Neither exercise nor difference in FIO2 level affected response accuracy. An additional experiment indicated that cognitive function was not altered without exercise. These results suggest that the improvement in cognitive function is attributable to exercise, and that hypoxia has no effects on cognitive function at least under the present experimental condition. Exercise-cognition interaction should be further investigated under various environmental and exercise conditions. © 2013 Ando et al.

  • Effects of strenuous exercise on visual perception are independent of visual resolution
    Soichi Ando; Masahiro Kokubu; Satoshi Nakae; Misaka Kimura; Tatsuya Hojo; Naoyuki Ebine
    PHYSIOLOGY & BEHAVIOR, PERGAMON-ELSEVIER SCIENCE LTD, 106巻, 2号, 掲載ページ 117-121, 出版日 2012年05月, 査読付, Strenuous exercise may have the detrimental effects on visual perception. However, it is unclear whether visual resolution is related to the detrimental effects on visual perception. The purpose of this study was to examine whether the effects of strenuous exercise on visual perception are dependent on visual resolution. Given that visual resolution decreases in the periphery of the visual field, we hypothesized that if visual resolution plays a role in the detrimental effects on visual perception, the detrimental effects may be exaggerated toward the periphery of the visual field. Simple visual reaction time was measured at rest and during cycling at 40% and 75% peak oxygen uptakes (VO2). Visual stimuli were randomly presented at 2 degrees, 10 degrees, 30 degrees, and 50 degrees to either the right or left of the midpoint between the eyes with equal probability. RT was fractionated into premotor and motor components (i.e. premotor time and motor time) based on electromyographic recording. The premotor time during exercise at 40% peak VO2 was not different from that at rest. In contrast, the premotor time during exercise at 75% peak VO2 was significantly longer than that at rest (p = 0.018). The increase in the premotor time was observed irrespective of eccentricity, and the detrimental effects were not exaggerated toward the periphery of the visual field. The motor time was not affected by exercise. The current findings suggest that the detrimental effects of strenuous exercise on visual perception are independent of visual resolution.

Physical and performance characteristics of Japanese division 1 collegiate football players. J Strength Cond Res 25(12): 3368-3377, 2011-This study aimed to establish the physical and performance characteristics of football players in the Japanese Division 1 collegiate football program and perform a comparison of these characteristics between Japanese (n = 208) and US Division 1 football players (n = 797). The following comparisons were made: (a) between a higher-ranked university team vs. a lower-ranked university team in Japan, (b) between different playing positions in Japan, (c) between starters and nonstarters in Japan, and (d) between playing positions in Japan vs. those in the United States. The results of this study suggest that players in the higher-ranked university team were heavier, stronger in back squat, jumped higher, and had greater power than those on the lower-ranked team. Furthermore, linemen were generally characterized by larger size, greater strength, and more fat as compared with backs. On the other hand, backs tended to be faster, smaller in physical size, have higher vertical jump height, and show greater relative strength than linemen did. Starters were taller, heavier, stronger, had more powerful, and more fat-free mass than nonstarters. Finally, our results revealed that players in the United States were superior to players in Japan in all body status comparisons (p < 0.01). This study revealed that performance and superior body composition are essential for the success of a football player. Power and strength seem to be key factors in defining good football performance.

  • Does cerebral oxygenation affect cognitive function during exercise?
    Soichi Ando; Masahiro Kokubu; Yosuke Yamada; Misaka Kimura
    EUROPEAN JOURNAL OF APPLIED PHYSIOLOGY, SPRINGER, 111巻, 9号, 掲載ページ 1973-1982, 出版日 2011年09月, 査読付, This study tested whether cerebral oxygenation affects cognitive function during exercise. We measured reaction times (RT) of 12 participants while they performed a modified version of the Eriksen flanker task, at rest and while cycling. In the exercise condition, participants performed the cognitive task at rest and while cycling at three workloads [40, 60, and 80% of peak oxygen uptake ((V) over dotO(2))]. In the control condition, the workload was fixed at 20 W. RT was divided into premotor and motor components based on surface electromyographic recordings. The premotor component of RT (premotor time) was used to evaluate the effects of acute exercise on cognitive function. Cerebral oxygenation was monitored during the cognitive task over the right frontal cortex using near-infrared spectroscopy. In the exercise condition, we found that premotor time significantly decreased during exercise at 60% peak (V) over dotO(2) relative to rest. However, this improvement was not observed during exercise at 80% peak (V) over dotO(2). In the control condition, premotor time did not change during exercise. Cerebral oxygenation during exercise at 60% peak (V) over dotO(2) was not significantly different from that at rest, while cerebral oxygenation substantially decreased during exercise at 80% peak (V) over dotO(2). The present results suggest that an improvement in cognitive function occurs during moderate exercise, independent of cerebral oxygenation.

  • Reaction time to peripheral visual stimuli during exercise under hypoxia

Reaction time to peripheral visual stimuli during exercise under hypoxia. J Appl Physiol 108: 1210-1216, 2010. First published February 18, 2010; doi:10.1152/japplphysiol.01115.2009.-The purpose of this study was to test the hypothesis that decrease in cerebral oxygenation compromises an individual's ability to respond to peripheral visual stimuli during exercise. We measured the simple reaction time (RT) to peripheral visual stimuli at rest and during and after cycling at three different workloads [40%, 60%, and 80% peak oxygen uptake ((V) over dotO(2))] under either normoxia [inspired fraction of oxygen (FI(O2)) = 0.21] or normobaric hypoxia (FI(O2)) = 0.16). Peripheral visual stimuli were presented at 10 degrees to either the right or the left of the midpoint of the eyes. Cerebral oxygenation was monitored during the RT measurement over the right frontal cortex with near-infrared spectroscopy. We used the premotor component of RT (premotor time) to assess effects of exercise on the central process. The premotor time was significantly longer during exercise at 80% peak (V)over dotO(2) (normoxia: 214.2 +/- 33.0 ms, hypoxia: 221.5 +/- 30.1 ms) relative to that at rest (normoxia: 201.0 +/- 27.2 ms, hypoxia: 202.9 +/- 29.7 ms) (P < 0.01). Under normoxia, cerebral oxygenation gradually increased up to 60% peak (V) over dotO(2) and then decreased to the resting level at 80% peak (V) over dotO(2). Under hypoxia, cerebral oxygenation progressively decreased as exercise workload increased. We found a strong correlation between increase in premotor time and decrease in cerebral oxygenation (r(2) = 0.89, P < 0.01), suggesting that increase in premotor time during exercise is associated with decrease in cerebral oxygenation. Accordingly, exercise at high altitude may compromise visual perceptual performance.

  • Effects of Exercise on Reaction Time to Peripheral Visual Stimuli
    Soichi Ando
    ADVANCES IN BIOMEDICAL RESEARCH, PROCEEDINGS, WORLD SCIENTIFIC AND ENGINEERING ACAD AND SOC, 掲載ページ 260-+, 出版日 2010年, 査読付, Vision is one of the most important sensory modalities in humans. Visual reaction time (RT) is the time from the appearance of a visual stimulus to the onset of motor output, and it has been used to assess perceptual and cognitive abilities in athletes. Visual field is composed of central and peripheral components. The ability to respond to peripheral visual stimuli as quickly as possible may be relevant to ball sports in which capturing visual information from the periphery of the visual field plays a role in performance. The purpose of this study was to examine effects of acute exercise under normoxia, hypoxia, and hyperoxia on the ability to respond to peripheral visual stimuli. Results showed that: (1) under normoxia, premotor component of RT (Premotor time) to peripheral visual stimuli was vulnerable to exercise as compared with that to central visual stimuli; (2) under normoxia, RT to peripheral visual stimuli increased during exercise at high workloads above the ventilatory threshold (VT) relative to that at rest, while the RT was not affected by exercise at the VT and below the VT; (3) under hypoxia, Premotor time to peripheral visual stimuli increased during exercise at low, moderate, and high workloads, and the increase in Premotor time was accompanied with decrease in cerebral oxygenation; and (4) under hyperoxia, Premotor time to peripheral visual stimuli was not different between at rest and during exercise at high workloads. These findings suggest that exercise at high workloads has detrimental effects on the ability to respond to peripheral visual stimuli unless oxygen availability was increased. Cerebral oxygenation may play a key role in visual perceptual performance during exercise.

    日本生理人類学会誌, 日本生理人類学会, 14巻, 4号, 掲載ページ 157-162, 出版日 2009年11月25日, The purpose of this study was to examine cerebral oxygenation in individuals with cervical spinal cord injury (SCI) during light exercise under normoxia and hypoxia. We used near-infrared spectroscopy to measure changes in oxyhemoglobin (oxyHb), deoxyhemoglobin (deoxyHb), and total hemoglobin (totalHb). In both the SCI and Control groups, deoxyHb increased during exercise under normoxia and hypoxia relative to rest. OxyHb slightly increased during exercise in the Control group. However, oxyHb decreased during exercise under hypoxia in the SCI group. These results might come from the decreased oxygen delivering capacity in individuals with SCI which was likely to result from the autonomic nervous system dysfunction and decreased skeletal muscle pump activity, possibly due to disuse atrophy.

  • The order of gaze shifts affects spatial and temporal aspects of discrete bimanual pointing movements
    Masahiro Kokubu; Soichi Ando; Shingo Oda
    EXPERIMENTAL BRAIN RESEARCH, SPRINGER, 198巻, 4号, 掲載ページ 501-511, 出版日 2009年10月, 査読付, We investigated whether the order of gaze shifts affected spatial and temporal aspects of discrete bimanual pointing movements. Ten male participants concurrently executed bimanual pointing movements as quickly and accurately as possible to left and right lateral targets presented with the same and different amplitudes. They were asked to gaze initially at the left target and subsequently at the right target, or vice versa. Each hand showed less variable error and a faster reaction when the initial gaze shifted to the corresponding target than when the subsequent gaze shifted to it. For the same-amplitude targets, constant error (CE) was not influenced by the gaze order conditions. However, for the different-amplitude targets, CE for the short-amplitude target became larger when they initially gazed at the long-amplitude target than when they initially gazed at the short-amplitude target. The larger overshoot of the hand for the short-amplitude target occurred when the participants could not afford to foveate the target. Our results suggest that the order of gaze shifts determines whether asymmetric amplitude assimilation between the two hands occurs or not. Fast, consistent, and accurate bimanual pointing movements might be attributable to updating gaze-centered representations of target positions.

  • Proximal electrode placement improves the estimation of body composition in obese and lean elderly during segmental bioelectrical impedance analysis

    EUROPEAN JOURNAL OF APPLIED PHYSIOLOGY, SPRINGER, 107巻, 2号, 掲載ページ 135-144, 出版日 2009年09月, 査読付, Bioelectrical impedance analysis (BIA) is an affordable, non-invasive, easy-to-operate, and fast alternative method to assess body composition. However, BIA tends to overestimate the percent body fat (%BF) in lean elderly and underestimate %BF in obese elderly people. This study examined whether proximal electrode placement eliminates this problem. Forty-two elderly men and women (64-96 years) who had a wide range of BMI [22.4 +/- A 3.3 kg/m(2) (mean +/- A SD), range 16.8-33.9 kg/m(2)] and %BF (11.3-44.8%) participated in this study. Using (2)H and (18)O dilutions as the criterion for measuring total body water (TBW), we compared various BIA electrode placements; wrist-to-ankle, arm-to-arm, leg-to-leg, elbow-to-knee, five- and nine-segment models, and the combination of distal (wrists or ankles) and proximal (elbows or knees) electrodes. TBW was most strongly correlated with the square height divided by the impedance between the knees and elbows (H (2)/Z (proximal); r = 0.965, P < 0.001). In the wrist-to-ankle, arm-to-arm, leg-to-leg, and five-segment models, we observed systematic errors associated with %BF (P < 0.05). After including the impedance ratio of the proximal to distal segments (P/D) as an independent variable, none of the BIA methods examined showed any systematic bias against %BF. In addition, all methods were able to estimate TBW more accurately (e.g., in the wrist-to-ankle model, from R (2) = 0.90, SEE = 1.69 kg to R (2) = 0.94, SEE = 1.30 kg). The results suggest that BIA using distal electrodes alone tends to overestimate TBW in obese and underestimate TBW in lean subjects, while proximal electrodes improve the accuracy of body composition measurements.

  • Single-trial reconstruction of finger-pinch forces from human motor-cortical activation measured by near-infrared spectroscopy (NIRS)
    Isao Nambu; Rieko Osu; Masa-aki Sato; Soichi Ando; Mitsuo Kawato; Eiichi Naito
    NEUROIMAGE, ACADEMIC PRESS INC ELSEVIER SCIENCE, 47巻, 2号, 掲載ページ 628-637, 出版日 2009年08月, 査読付, Near-infrared spectroscopy (NIRS) has recently been used to measure human motor-cortical activation, enabling the classification of the content of a sensory-motor event such as whether the left or right hand was used. Here, we advance this NIRS application by demonstrating quantitative estimates of multiple sensory-motor events from single-trial NIRS signals. It is known that different degrees of sensory-motor activation are required to generate various hand/finger force levels. Thus, using a sparse linear regression method, we examined whether the temporal changes in different force levels could be reconstructed from NIRS signals. We measured the relative changes in oxyhemoglobin concentrations in the bilateral sensory-motor cortices while participants performed an isometric finger-pinch force production with their thumb and index finger by repeatedly exerting one of three target forces (25, 50, or 75% of the maximum voluntary contraction) for 12 s. To reconstruct the generated forces, we determined the regression parameters from the training datasets and applied these parameters to new test datasets to validate the parameters in the single-trial reconstruction. The temporal changes in the three different levels of generated forces, as well as the baseline resting state, could be reconstructed, even for the test datasets. The best reconstruction was achieved when using only the selected NIRS channels dominantly located in the contralateral sensory-motor cortex, and with a four second hemodynamic delay. These data demonstrate the potential for reconstructing different levels of external loads (forces) from those of the internal loads (activation) in the human brain using NIRS. (C) 2009 Elsevier Inc.

    EUROPEAN JOURNAL OF APPLIED PHYSIOLOGY, SPRINGER, 106巻, 1号, 掲載ページ 61-69, 出版日 2009年05月, 査読付, The purpose of this study was to test if increased oxygen availability affected simple reaction time (RT) to peripheral visual stimuli during exercise. Twelve male participants performed RT tasks at rest, during cycling with three different workloads (100, 150, and 200 W), and after exercise. We fractionated RT into Premotor time and Motor time. Under normoxia, Premotor time significantly increased during exercise at 200 W (mean +/- A SD, 224.7 +/- A 34.8 ms) relative to that at rest (213.3 +/- A 34.1 ms) (P < 0.05). In contrast, we found no difference in Premotor time between at rest (214.0 +/- A 27.0 ms) and at 200 W (213.0 +/- A 21.6 ms) under hyperoxia. Furthermore, Premotor time significantly decreased at 150 W (201.3 +/- A 22.4 ms) relative to that at rest under hyperoxia (P < 0.05). These results suggest that increased oxygen availability during exercise has beneficial effects on perceptual performance.

    INTERNATIONAL JOURNAL OF SPORTS MEDICINE, GEORG THIEME VERLAG KG, 29巻, 12号, 掲載ページ 994-998, 出版日 2008年12月, 査読付, We examined the effects of acute exercise on reaction time to Visual stimuli presented in the central portion and periphery of the visual field. Twelve participants performed reaction time tasks at rest and during cycling at 65% peak oxygen uptake in two visual conditions. We used circular black-and-white checkerboard patterns as visual Stimuli. The participants were asked to respond as quickly as possible to pattern reversal of the visual Stimulus by releasing a response button. Reaction time was fractionated into Premotor time and Motor time. Premotor time in the peripheral condition significantly increased (p < 0.025) during exercise (mean +/- SE; 195.9 +/- 7.9 ms) from that at rest (183.7 +/- 6.8 ms). Premotor time in the central condition did not differ between at rest (185.3 +/- 7.6 ms) and during exercise (188.4 +/- 6.6 ms). These data suggest that the ability to respond to visual stimuli presented in the periphery of the visual field is vulnerable to moderate to severe exercise, as compared with the ability to respond to visual stimuli presented in the central portion of the visual field. An exercise-induced increase in arousal level and a consequent narrowing of attentional focus would explain the present results.

  • Increase in reaction time for the peripheral visual field during exercise above the ventilatory threshold
    S Ando; T Kimura; T Hamada; M Kokubu; T Moritani; S Oda
    EUROPEAN JOURNAL OF APPLIED PHYSIOLOGY, SPRINGER, 94巻, 4号, 掲載ページ 461-467, 出版日 2005年07月, 査読付, The purpose of the present study was to determine whether reaction time (RT) for the peripheral visual field increases at exercise intensity above the ventilatory threshold (VT) during incremental exercise and to examine the relationship between aerobic capacity and the extent of increase in the RT. Nine healthy subjects performed a simple manual RT task for the peripheral visual field at rest, during exercise on a cycle ergometer, and immediately after exercise. After warm-up exercise, the subjects cycled at 40 W for 3 min, increasing by 40 W every 3 min until 240 W in a step-wise manner. During incremental exercise, RT measurements were performed 1 min and 30 s after the start of every increase in workload. The RT for the peripheral visual field significantly increased at exercise intensity above VT, as compared with at rest. The increase in the RT, which was calculated by subtracting the RT at rest from the RT at 240 W, negatively correlated with maximal oxygen uptake (<(V)overdot > O-2max) for each subject (r = -0.73, P < 0.05). It is likely that high aerobic capacity attenuates the increase in the RT for the peripheral visual field during exhaustive exercise.

  • Retention of practice effects on simple reaction time for peripheral and central visual fields
    S Ando; N Kida; S Oda
    PERCEPTUAL AND MOTOR SKILLS, PERCEPTUAL MOTOR SKILLS, 98巻, 3号, 掲載ページ 897-900, 出版日 2004年06月, 査読付, Previous researchers reported that EMG Reaction Time (RT) for a key press in peripheral and central visual fields decreases with practice. The practice effects on the RT for peripheral visual field transferred to the RT for the central visual field, and vice versa. The present study investigated whether practice effects on the RT for peripheral and central visual fields and the corresponding transfer effects lasted 3 wk. or not. 16 male subjects were divided into two groups, one practicing using peripheral vision, the other practicing using central vision. Each group practiced RT tasks for 3 wk. 3 wk. after practice terminated, the practice effects and the transfer effects were maintained as a significant decrease in RT was found over the 3-wk. retention interval, suggesting that once the neural correlates of responding quickly are improved, the improved performances are remarkably stable for at least 3 wk.

    PERCEPTUAL AND MOTOR SKILLS, PERCEPTUAL MOTOR SKILLS, 95巻, 3号, 掲載ページ 806-812, 出版日 2002年12月, 査読付, The present study examined whether attention can be evenly distributed within the large area of the visual field. The stimulus was presented at one of four locations on the horizontal meridian (0degrees, 10degrees, 20degrees, and 30degrees to the right). In the Fixed Location condition, the stimulus appeared repeatedly at the same location. In the Random Location condition, the stimulus appeared at one of four locations as determined randomly with equal probability. Reaction times (RTs) in the Random Location condition were significantly longer than those in the Fixed Location condition at the 0degrees and 30degrees locations, while there were no significant differences at the 10degrees and 20degrees locations. The differences in the RT between conditions were significantly larger at the 0degrees and 30degrees locations than those at the 10degrees and 20degrees locations. These-results suggest that attention was oriented to intermediate locations within the large area of the visual field.

  • Practice effects on reaction time for peripheral and central visual fields
    S Ando; N Kida; S Oda
    PERCEPTUAL AND MOTOR SKILLS, PERCEPTUAL MOTOR SKILLS, 95巻, 3号, 掲載ページ 747-751, 出版日 2002年12月, 査読付, The present study examined whether EMG-RT (RT) for a key press to stimulus in peripheral and central visual fields decreases with practice. 16 male students were divided into two groups, one practicing using peripheral vision, the other practicing using central vision. Before and after practice, RT was measured for peripheral and central visual fields. Each group practiced three blocks of 25 trials five days a week for three weeks. RT for peripheral and central visual fields decreased with practice. Practice effects on RT for the peripheral visual field extended to RT for the central visual field, and vice versa. It is suggested that the transfer may reflect the decrease in the central nervous system's processing time in common between two RT tasks.

  • Central and peripheral visual reaction time of soccer players and nonathletes
    S Ando; N Kida; S Oda
    PERCEPTUAL AND MOTOR SKILLS, PERCEPTUAL MOTOR SKILLS, 92巻, 3号, 掲載ページ 786-794, 出版日 2001年06月, 査読付, Visual Reaction Time (RT) was measured by presenting three different sizes of stimulus to the central and peripheral fields of vision in 6 soccer players and 6 nonathletes. An electromyogram was recorded from the flexor digitorum superficialis muscle of the responding forearm. Peripheral visual RT was longer in comparison to central visual RT due to an increment in Premotor Time. The soccer players showed shorter Premotor Times during central and peripheral visual RT tasks than nonathletes, suggesting that the soccer players are better able to respond quickly to a stimulus presented to peripheral as well as central positions.

  • サッカー選手と一般学生における中心視野と周辺視野の反応時間
    安藤創一; 来田宣幸; 小田伸午
    京都体育学研究, 京都体育学会, 15巻, 掲載ページ 7-13, 出版日 1999年07月, 査読付, Visual reaction time of 20 soccer players and 13 nonathlete university students was measured using three different sizes of stimulus in central and peripheral vision.The results were summarized as follows: 1) Central visual reaction time of soccer players increased significantly with a decrease in size of a stimulus, while peripheral visual reaction time of nonathletes increased significantly with a decrease in size of the stimulus.2) In soccer players the correlation between peripheral visual reaction time and central visual reaction time was higher when the size of the stimulus was small. In nonathletes,however,correlation of the same parameters was higher when the size of the stimulus was large. These results suggest that soccer players have a higher ability of peripheral visual perception to the smaller object than nonathletes,that might enable to make quick judgement and decision to the far distant ball in the soccer field.

  • なぜ運動による覚醒レベルの上昇は認知パフォーマンスを高めるのか?
    安藤 創一
    本研究の目的は,運動による覚醒レベルの上昇が認知パフォーマンスを向上させるメカニズム解明のために,運動による覚醒レベルの向上に関わる脳領域を同定すること,脳領域間の機能的結合の変化が覚醒レベルの変化に関与するかを明らかにすることであった.18名の実験参加者は,最高酸素摂取量の40%の運動強度での運動前後,および安静の前後に認知課題を行い,fMRIを用いて脳活動を撮像した.運動後に覚醒レベルは上昇し,認知パフォーマンスは向上した.運動による覚醒レベルの変化は,準備刺激に対する左下前頭回,右前頭極,および右背側帯状回皮質の活動増加と関係がみられた.さらに,覚醒レベルの変化は,これらの領域間での機能的結合の増加を伴っていた.本研究から,運動による覚醒レベルの上昇には,前頭前野,前頭極,帯状回皮質の領域間の神経ネットワークが関与し,この領域間のネットワークが高まることが認知パフォーマンスの向上に貢献することが示唆された.(著者抄録), (公財)石本記念デサントスポーツ科学振興財団, 出版日 2020年09月, デサントスポーツ科学, 41巻, 掲載ページ 3-9, 日本語, 0285-5739, 2758-4429, 2021110392

    小見山 高明; 檜垣 靖樹; 安藤 創一; 須藤 みず紀
    高強度運動時の認知機能の低下に関わる要因として、脳血流と脳酸素飽和度が関与している可能性がある。本研究では、15名の健常成人男性(年齢:23.3±1.8歳、身長:1.70±0.06m、体重:64.4±5.8kg、最高酸素摂取量:47.3±6.4ml/kg/min)を対象に、中強度及び高強度の運動中に認知課題を実施し、同時に中大脳動脈血流速度と前頭前野の脳酸素飽和度の測定を行い、高強度運動時の認知機能の低下と脳血流及び脳酸素飽和度の変化との関係性を明らかにすることを目的とした。高強度運動時には、安静時及び中強度運動時と比較して認知課題の正解率は有意な低下が認められた(安静時:P<0.05、中強度運動時:P<0.01)。一方で反応時間に有意な差は認められなかった(P=0.31)。脳血流速度は安静時と比較して中強度運動時に増加し(P<0.01)、高強度運動時では中強度運動時と比較して有意な低下がみられた(P<0.01)。脳酸素飽和度は安静時と比較して高強度運動時に低下する傾向が認められた(P=0.058)。したがって、高強度運動時の脳血流や脳酸素飽和度の低下は、認知機能の低下に関与している可能性が示唆された。(著者抄録), 石本記念デサントスポーツ科学振興財団事務局, 出版日 2017年05月, デサントスポーツ科学, 38巻, 掲載ページ 207-215, 日本語, 0285-5739, 2758-4429, 2018065236, 40021225780

    加齢に伴う廃用性筋萎縮(サルコペニア)モデル作出を目的としたギプス固定マウスの有用性を検証した。1週間片脚ギプス固定後遅筋線維から構成されるヒラメ筋(Sol),速筋線維から構成される足底筋(Pla)を抽出し,筋重量を計測した。無処置マウスでは実験実施前後において体重に変化が見られなかったが,ギプス固定マウスでは処置後で有意な体重減少を認め,各筋の体重あたりの筋重量も顕著に減少していた。体重減少は固定による精神的ストレス,食欲減退も考えられるが,食餌摂取量は無処置対照群と差異はなく,体重減少も2週間で正常化した。短期ギプス固定は筋萎縮誘発には有効であるが,非固定脚の代償的負荷の影響や骨格筋細胞レベルでの変化を検証する必要性を示唆した。, 福岡大学, 出版日 2015年03月, 福岡大学スポーツ科学研究, 45巻, 2号, 掲載ページ 53-58, 日本語, 1345-9244, 2015224194, 110009889022

    日本学術振興会, 科学研究費助成事業, 電気通信大学, 挑戦的研究(萌芽), 運動が脳機能の維持や向上に効果的であることは広く知られている.ヒトを対象とした研究では,運動が脳機能にもたらす効果の検証にはfMRIやNIRSなどのイメージング機器を用いることが一般的である.しかし,メカニズムの解明など侵襲的な手法が必要な場合は動物モデルを用いる必要があり,現在知られている運動と脳に関するエビデンスには,ヒトでは直接検証されていないものが多い.これまでに運動が海馬を活性化させるということが提唱されているが,その根拠となっているものは,動物モデルを用いた研究である.しかし,上述の動物モデルの研究とヒト研究との潜在的な違いを考えると,運動がヒトの海馬を活性化することを直接的に明らかにすることは,科学的エビデンスを正しく伝えるとともに,なぜ一回の運動でもヒトの脳機能の維持・向上につながるのかを示す重要な知見となるものである.そこで本研究では,“運動はヒトの海馬を本当に活性化するのか?”というこれまで直接的に明らかにされていない疑問を解決することを目的とする. 令和3年度は海馬における内因性のドーパミン遊離を定量化することを試みている.薬剤としてドーパミンD2受容体の拮抗薬であり[11C]ラクロプライドを用いたPET実験のデータをもとに解析を行っている.現在,この解析のための方法を検討している段階であり,本研究により,一過性の運動によりドーパミン神経を介して海馬が活性化するかどうかが明らかになることが期待される., 21K19702

    日本学術振興会, 科学研究費助成事業, 名古屋大学, 基盤研究(C), 運動と認知の二重課題について,一方の課題の種類や難易度を変えた時の,両方のパフォーマンスへの影響と加齢による違い,さらに二重課題開始時の呼吸循環応答の動態を検討した.その結果,1)自転車運動の回転数を変えて二重課題を実施すると,運動の正確性が低下し,高齢者では低速時に速く漕ぐ傾向があること,2)認知課題を変えた時の二重課題では,運動パフォーマンスが作業記憶課題で低下し,認知パフォーマンスでは注意機能が影響を受けやすく,高齢者では向上する場合もあること,3)二重課題開始時の各種応答は単独運動より大きく,それは認知と運動の効果が単純加算されること,高齢者の応答は若年者より遅いことが明らかとなった., 17K01758

    檜垣 靖樹; 田中 宏暁; 須藤 みず紀; 道下 竜馬; 安藤 創一; 上原 吉就; 安野 哲彦
    日本学術振興会, 科学研究費助成事業, 福岡大学, 基盤研究(B), 本研究では、骨格筋糖代謝調節機構における重要な分子である、一酸化窒素を合成する酵素(nNOS)の遺伝子発現について、身体不活動、加齢および運動に対する応答にDNAメチル化が関与しているか、検討した。その結果、身体不活動により骨格筋のnNOSのDNAメチル化の増加とタンパク発現の減少を認め、エピジェネティックな遺伝子修飾が関与していることが明らかとなった。また、加齢によりnNOSタンパク発現の亢進を認め、豊かな環境はその亢進を減弱させたが、それらの調節機構にエピジェネティックな遺伝子修飾の関与を証明するには至らなかった。これらの研究成果の一部は、国内外の学術学会及び学術雑誌にて公開した。, 15H03082

  • 運動が認知機能を高める機序の解明:PETを用いたドーパミンの神経伝達からの検証
    安藤 創一; 田代 学; 藤本 敏彦; 檜垣 靖樹
    日本学術振興会, 科学研究費助成事業, 電気通信大学, 基盤研究(B), 本研究では,一過性の運動による認知パフォーマンスの向上に脳内でのドーパミンを介した神経伝達が関与するという仮説を検証することを目的とした.被験者は,仰臥位での自転車エルゴメーターによる運動時に認知課題を行い,内因性ドーパミンの遊離を評価した.その結果,運動により認知パフォーマンスの向上と内因性ドーパミンの遊離がみられた.これらの結果は,一過性の運動による認知パフォーマンスの向上に内因性ドーパミンの遊離が関与することを示唆するものである., 16H03230

  • 骨格筋細胞における核とミトコンドリアの共遊走機構の解明
    檜垣 靖樹; 須藤 みず紀; 兼岡 秀俊; 安藤 創一; 安野 哲彦
    日本学術振興会, 科学研究費助成事業, 福岡大学, 挑戦的萌芽研究, 肥満者の骨格筋細胞内には多量の脂肪が貯蔵されており、脂肪量とインスリン感受性は負の相関を示す。一方、インスリン感受性が亢進している持久鍛錬者の筋細胞内脂肪量は、肥満者よりもさらに多い。しかし、なぜ持久鍛錬者は多量の筋細胞内脂肪を有するのに、インスリン抵抗性を引き起こさないのか、不明である。 本研究では、iPS細胞由来の筋細胞を用いて、核の周辺にミトコンドリアと脂肪滴が局在することを観察した。我々は、これらの局在環境がインスリン抵抗性と関連していると考えている。, 15K12677

  • 低酸素環境下での運動中の認知機能:閾値の検討と神経活動の評価法の開発
    安藤 創一; 小見山 高明; 片山 敬章; 檜垣 靖樹; 須藤 みず紀
    日本学術振興会, 科学研究費助成事業, 電気通信大学, 挑戦的萌芽研究, 本研究の目的は,低酸素環境下での運動が認知機能に与える影響を明らかにすることであった.本研究により,低酸素環境下(吸入気酸素濃度:0.12-0.13)での運動中であっても認知機能が向上することが示された.しかしながら,低酸素環境下での運動中に動脈血酸素飽和度が低下した被験者ほど認知機能の向上がみられなかった.したがって,動脈血酸素飽和度の低下は,低酸素環境下での運動中の認知機能に影響を与える大きな要因であることが明らかとなった., 15K12664

  • 運動中の認知機能の低下を防ぐ方法と認知機能を改善・向上させるプログラムの開発
    安藤 創一
    日本学術振興会, 科学研究費助成事業, 若手研究(A), 本研究より得られた主な研究成果は以下の通りである,1) 酸素濃度が15%に低下した低酸素環境下においても,通常環境下と同様に運動により認知機能が向上する,2) 高温環境下での高強度運動中に頸部への冷却を行っても,認知機能には影響を与えない(Ando et al. 2015),3) 朝食を欠食すると認知機能は低下するが,朝食摂取の有無に関係なく運動中に認知機能は向上する(Komiyama et al. 2016).さらに,これまでの国内外の研究成果を精査し,脳血流の増加および組織酸素飽和度の変化が運動により認知機能を直接的に向上させている要因ではないことを示唆した(Ando 2016)., 25702039

  • 筋収縮刺激による培養筋細胞を用いたミトコンドリア遊走機構の解明
    檜垣 靖樹; 須藤 みず紀; 安藤 創一; 安野 哲彦; 兼岡 秀俊
    日本学術振興会, 科学研究費助成事業, 福岡大学, 挑戦的萌芽研究, 肥満者の骨格筋細胞内には多量の脂肪が貯蔵されており、脂肪量とインスリン感受性は負の相関を示す。一方、インスリン感受性が亢進している持久鍛錬者の筋細胞内脂肪量は、肥満者よりもさらに多い。しかし、なぜ持久鍛錬者は多量の筋細胞内脂肪を有するのに、インスリン抵抗性を引き起こさないのか、不明である。 本研究では、培養細胞実験系で、核の周辺にミトコンドリアと脂肪滴が局在すること、また、それらの解剖学的位置関係を有しながら脂肪滴を取り囲む現象を捉えた動画像を得た。インスリン抵抗性の背景に、ミトコンドリアと脂肪滴の解剖学的位置関係が影響する可能性が考えられた。, 25560345

  • 酸化ストレスは筋トレ-ニング及び筋不活動による骨格筋糖輸送適応を制御する
    檜垣 靖樹; 田中 宏暁; 清永 明; 飛奈 卓郎; 須藤 みず紀; 安藤 創一; 山田 陽介
    日本学術振興会, 科学研究費助成事業, 福岡大学, 基盤研究(C), 骨格筋線維特性により異なるが、筋細胞には一酸化窒素合成酵素(NOS)の局在を認めることから、酸化ストレスの一つであるNOが、骨格筋の糖輸送の制御を担っているとの仮説を立てた。そこで、我々はトレーニングモデル及び不活動モデルの作成に着手し、上記仮説を検証可能な実験系を立ち上げた。そして、糖輸送の制御にNOSがどのようなメカニズムを持って制御しているか、エピジェネティックな変化を想定して実験を進めた。その結果、NOSプロモータ領域のCpGアイランドのメチル化の定量が可能となり、条件間でメチル化の程度が異なる可能性が示唆された。, 22500618

  • 運動中に周辺視野の知覚能力は低下するか?(低酸素環境下での反応時間からの検証)
    安藤 創一
    日本学術振興会, 科学研究費助成事業, 若手研究(B), 本研究の目的は、一過性の運動が周辺視野での知覚能力に及ぼす影響について検討することであった。通常環境下と低酸素環境下で行われた実験1の結果から、脳の組織酸素飽和度が低下すればするほど周辺視野の知覚能力が低下することが明らかとなった。さらに、実験2から高強度の運動中には周辺視野に注意を向ける能力が低下する可能性が示唆された。これらの結果から、サッカーなどの球技において周りが見えなくなる生理学的要因の解明につながることが期待される。, 21700622

  • 運動による生理的・心理的変化が周辺視野で見る能力に及ぼす影響
    安藤 創一
    日本学術振興会, 科学研究費助成事業, 大阪体育大学, 特別研究員奨励費, 本年度は、安静時および運動中に中心視野と周辺視野に呈示される視覚刺激に対する反応時間を測定した。運動には自転車エルゴメーター(コンビ社製75XL II)を用いた。実験は三日間に分けて行い、実験の初日に最高酸素摂取量を測定し、最高酸素摂取量の65%に相当する運動負荷を決定した。実験二日目および三日目には、中心視野と周辺視野のそれぞれに呈示される視覚刺激に対する反応時間を、安静時、運動中の順で測定した。視覚刺激の作成及び呈示にはプログラム言語MATLAB(Mathwork社)を用いた。中心視野と周辺視野の反応時間は異なる日に測定し、半数の実験参加者は中心視野→周辺視野の順で、残りの半数の参加者は周辺視野→中心視野の順で行った。安静時および自転車運動中には、反応時間と併せて心拍数(HR)、主観的運動強度(RPE)を測定した。その結果、運動中の周辺視野反応時間は安静時と比較して有意に大きい値を示した。一方、運動中の中心視野反応時間は安静時と差がみられなかった。HR&RPEはそれぞれの測定日の間で差がみられなかった。以上の結果から、周辺視野に呈示される視覚刺激に対して反応する能力が、中心視野に呈示される視覚刺激に対して反応する能力と比較して一過性の運動の影響を受けやすいことが示唆された。以上の結果は国際バイオメカニクス学会にて発表を行った後、国際雑誌に受理された(Ando, et. al. in press)。, 05J06459
