A group of researchers including Associate Professor Takeshi Hashimoto of College of Sport and Health Science and Mr. Hayato Tsukamoto, graduate student at Graduate School of Sport and Health Science, has scientifically found that post-exercise executive function (EF) improvement could be prolonged by conducting high-volume exercise, especially high-intensity exercise, and presented its findings in the journal of the American College of Sports Medicine, Medicine & Science in Sports & Exercise.

Differences in exercise volume were known to affect the magnitude of the health effects of aerobic exercise. However, the relationship between exercise volume and EF improvement or its endurance had not been elucidated. This research group studied the acute impact of differences in exercise volume (varying exercise intensity and duration) on EF, which governs decision-making capability. As a result, the group scientifically found that post-exercise EF improvement could be prolonged by conducting high-volume exercise, especially high-intensity exercise.
