Effects of the timing of exercise on the night sleep

The effects of physical exercises taken at different times in the day upon subjective sleep feeling were examined in five healthy university students (aged 20–22 years); morning exercise, evening exercise, and late evening exercise. The late evening exercise with the strength of 50–60% VO2max of 1 h has the effect of getting better subjective sleep feeling in the morning and the effect of the decreased daytime sleepiness.
