Abstract：The primary goal of the present study was to investigate the mediating effect of self-control on the relationship between physical activity and sleep quality among college students. 156 college students completed the daily diary survey to measure their physical activity, self-control level, and sleep quality for seven consecutive days. The results of the multilevel model analysis showed that: (1) daily physical activity could not predict the daily self-control and next daily sleep quality on the night, but the daily self-control could positively predict the next daily sleep quality. (2) Overall physical activity was positively correlated with self-control and sleep quality, and self-control played a partial mediating role between physical activity and sleep quality.
