青年期における運動習慣および日常的な身体活動が遂行機能とメンタルヘルスに与える効果

抄録

This study aimed at evaluating the effect of habitual exercise and the level of daily physical activity on executive function (i.e. inhibitory control) and mental health status in youth adults. Twenty-four undergraduate- and graduateuniversity students participated in this study. All of the subjects underwent evaluations of their mental health (The General Health Questionnaire 28; GHQ28), inhibitory control (Stroop Color and Word Test), past- and current- exercise habits, and daily physical activity levels (International Physical Activity Questionnaire Short Version). Current habitual exercise and the level of low intensity physical activity were inversely correlated with score for GHQ28. Past habitual exercise was inversely correlated with reaction time for incongruent trial of the Stroop Color and Word Test. The level of vigorous physical activity was inversely correlated to the accuracy for incongruent trial. This study demonstrates that the level of low intensity daily physical activity may improve inhibitory control and maintain the optimal status of mental health, while the level of vigorous intensity physical activity might lead to an impairment of inhibitory control in youth adults.
