| Outline of Final Research Achievements |
The purpose of this study investigated chronic effect of cognitive-motor control induced to aerobic exercise using Go/NoGo reaction time, event-related brain potential, and mood measurements. As a result of examining the acute effect of high-intensity interval, moderate-intensity, and self-paced intensity exercises, it was suggested that high-intensity interval exercise improves pleasant emotions and is effective for the brain's executive and inhibitory functions. In addition, the high-intensity interval group and the moderate-intensity interval group were subjected to exercise intervention three times a week for three months. As a result, it was suggested that high-intensity interval exercise was the most effective for chronic improvement of executive and inhibitory functions of the brain.

| Academic Significance and Societal Importance of the Research Achievements |
継続的な有酸素性運動は，高強度インターバル運動（90 s 高強度 + 60 s 低強度），中等強度運動（30 min ジョギング）のどちらにおいても脳の実行・抑制機能の向上に有効であることが示され，特に高強度インターバル運動の方がより強い効果が望めることが明らかとなった。このことは若年者の認知機能の維持増進に対して高強度インターバル運動が至適強度であることを示唆している。今後，高齢者においてその有効性が示せれば，認知症の予防などに高強度インターバル運動が役立つと考えられる。
