title: Effect of night exercise on the following partially deprived sleep.
abstract: Six trained male athletes (aged 24.3+/-2.9 years) performed cycling exercise from 23.00 to 23.50 h. From 00.30 to 07.00 h, the subjects followed a schedule that consisted of 30 min trying to fall asleep in bed and 60 min of being awake outside the bedroom. The control experiment was conducted without exercise under the same time schedule. An increase in rectal temperature induced by exercise was 1.9+/-0.4. After exercise, prolongation of sleep onset latency was observed only in the sleep period fron 00.30 to 01.00 h compared with the control night. Time spent in slow wave sleep throughout the night was significantly longer after exercise.
