Outline of Final Research Achievements

Recently many studies have reported that high-intensity interval exercise (HIIE) improves the ability of the cardiovascular system and of oxygen utilization in the muscles of sport athletes as well as normal healthy individuals and people with lifestyle-related diseases. In the present study, we investigated the effects of short-term HIIE on the psychological state and brain function. As a result, it was suggested that the HIIE in this study induced a temporal decrease in arousal levels after the HIIE during the recovery phases of decreased vigor and increased fatigue. During the period of increased fatigue sensation after the HIIE, corticospinal tract excitability of lower limb muscles tended to be decreased, while that of the upper limb muscles tended to be increased. Based on these studies, we suggested that the HIIE should be performed taking into consideration a transient change of psychological state and related changes of brain function that occurred after the HIIE.
