This study investigates the effect of mild physical activity before bedtime on the sleep pattern and heart rate during the night. Nine healthy subjects underwent a habituation night, a reference night, and a physical induction night. The physical induction night did not alter the sleep pattern. Physical activity before bedtime resulted in higher heart rate variance during slow-wave sleep. The low-frequency/high-frequency component (LF/HF) ratio during slow-wave sleep in the physical induction night was significantly higher than during the reference night. Increased mean heart rate and higher LF/HF ratio are related to decreased parasympathetic dominance. Exercise up to 1 h before bedtime thus seems to modify the quality of sleep.
这项研究调查了睡前轻度体育活动对夜间睡眠模式和心率的影响。9 名健康受试者经历了适应期夜晚、参考夜晚和体育诱导夜晚。体育诱导夜晚并没有改变睡眠模式。睡前体育活动导致慢波睡眠期间心率变异性增加。在物理诱导夜间，慢波睡眠中的低频/高频分量（LF/HF）比值明显高于参考夜间。平均心率增加和 LF/HF 比值升高与副交感神经支配减少有关。因此，睡前 1 小时内进行运动似乎可以改善睡眠质量。
