「Effect of night exercise on the following partially deprived sleep」

Six male athletes performed 50 minutes exercise before midnight. Thereafter, they followed a schedule that consisted of 30 min trying to sleep and 60 min of being awake. Prolonged sleep latency was observed only in the initial sleep period. Time spent in slow wave sleep throughout the night significantly increased after exercise.（夜間に運動させ、その後、30分睡眠／60分覚醒、という短時間の睡眠スケジュール時の睡眠構造を検討したところ、運動直後では寝つきの遅延、一晩の合計では徐波睡眠が増大した。）
