Outline of Final Research Achievements

We investigated the effects of central and peripheral fatigues on motor control and cardiovascular responses during exercise in a hot environment using electroencephalographic event-related potentials, near-infrared spectroscopy, and middle cerebral artery blood velocity. In addition, to investigate the motor skill with muscle fatigue, we examined the interlocking of upper and lower limbs movements. The results of hyperthermia-induced central fatigue showed that the mode of exercise is capable of modulating the central motor command. Also, the peripheral fatigue affects the output of the central motor command, which is brain activity. Finally, "how to relax" due to muscle fatigue was numerically presented.

Academic Significance and Societal Importance of the Research Achievements

高いレベルで運動パフォーマンスを発揮するためには疲労のマネジメントが重要である。しかし、疲労時のモーターコントロールが何によってどのように影響を受けるのかは不明な点が多い。特に夏季オリンピックのように真夏に実施されるハイレベルの大会では末梢性の筋疲労だけでなく、体温上昇や長時間運動による中枢性疲労の影響も検討する必要がある。これらの数値化によって、疲労による事故回避の指標を構築できる可能性を示すことができた。
