Outline of Final Research Achievements

The present study investigated the effect of sleep quality on athletic performance, the mechanism underlying decrease in sleep quality, and the effect of replenishment of the deficient substance on sleep and athletic performance. We demonstrated that the sleep quality affected cognitive performance during a relatively intense aerobic exercise. We found using metabolomics that carnosine and ornithine were decreased by poor sleep quality. Furthermore, the present study suggested that intake of carnosine improved sleep and athletic performance.
