The effects of six graded and measured exercise activities on sleep patterns were investigated in two healthy young men. Electrophysiological recording were made continuously throughout the night to distinguish sleep states. This experiment was designed to test the hypothesis of a relation between physical activity and slow-wave sleep (SWS: stages 3 and 4 of non-REM sleep). A progressive increase in SWS over the whole-night sleep record was found with progressively increasing physical fatigue. A fall in rapid-eye-movement (REM) sleep and at higher exercise levels, of stage 2 sleep, was found. The results support the hypothesis that SWS is involved in the recovery process from fatigue.
在两名健康的年轻男性中研究了六种分级和测量的运动活动对睡眠模式的影响。整个晚上持续进行电生理记录以区分睡眠状态。本实验旨在检验体力活动与慢波睡眠（SWS：非快速眼动睡眠的3期和4期）之间关系的假设。发现在整个夜间睡眠记录中，随着身体疲劳程度的逐渐增加，慢波睡眠也逐渐增加。还发现快速眼动（REM）睡眠减少，在较高运动水平下，2期睡眠也减少。这些结果支持了慢波睡眠参与疲劳恢复过程的假设。
