Outline of Final Research Achievements

Participants were asked to repeatedly perform short periods (10 mins) of light-to-moderate exercises including closed- and open-skill elements approximately every hour during the day, respectively. As a result, the influence of the exercise skill is not detected in a cognitive work performance such as the mental arithmetic work, but it was suggested that working memory, a sub-function of executive function, tended to be temporarily higher when participants performed the open-skill exercise compared with the closed-skill exercise. Although further investigation is required into the method and time of exercise, these results suggest that exercise skills may influence the effect of short, fragmented exercise during the day on executive function.

Academic Significance and Societal Importance of the Research Achievements

軽-中強度の短時間運動を行うことによってその後の実行機能が高まることが報告されているが、本研究では、そのような運動を日中に細切れに行った場合について、その間の実行機能が運動スキル（クローズドスキルおよびオープンスキル）の影響を受ける可能性があることを示唆した。今後さらに検討が必要ではあるが、本研究の結果より、実際に、職場や学校における休憩時間にどのような運動を行うかで実行機能への影響が異なる可能性があることが考えられる。
