Outline of Final Research Achievements

The purpose of this study was to investigated that the relationship of a physical activity and the circadian rhythm of the cortisol in saliva in early childhood., and to prove that the physical activity contributes to develop the circadian rhythms of early childhood. As a result, a velocity of cortisol secretion after getting up was higher significantly caused by higher amount of physical activity that intensity is stronger than walking level. But, the velocity was not higher significantly in a group at lower amount of physical activity. Therefore, it was suggested that the physical activity that intensity is stronger than walking level is heightened the cortisol secretion velocity immediately after getting up, and to produce the development of circadian rhythms.
