16名高度健康的男性自行车运动员完成了两个60小时的实验室治疗，包括基线之夜，实验治疗之夜和恢复之夜。在平衡的顺序，受试者1）周期为3小时，在65-75%的心率储备结合强光照射（3000勒克斯）光，和2）暴露于3小时脉冲的强光（3000勒克斯）单独。ResultsOn the baseline and recovery nights，受试者保持他们通常的睡眠-觉醒时间表。在治疗之夜，运动+强光或单独强光集中在他们通常醒来时间之前6小时，然后是治疗后30分钟的就寝时间。在实验处理期间，照明为3000勒克斯，在睡眠期间为0勒克斯，在其他时间为50勒克斯。用Actillume（Ambulatory Monitoring，Inc.，Ardsley，NY）腕部监测器来定义睡眠开始潜伏期（SOL）、睡眠开始后的觉醒（WASO）和总睡眠时间。每天早晨还收集SOL、WASO和失眠的主观评估。客观或主观的睡眠变量之间没有显着差异treatments.ConclusionsThese数据是不一致的普遍意见，睡前不久的剧烈运动扰乱睡眠。
MethodsSixteen highly fit male cyclists completed each of two 60-h laboratory treatments involving a baseline night, an experimental treatment night, and a recovery night. In counterbalanced order, subjects 1) cycled for 3 h at 65-75% of heart rate reserve combined with bright light exposure (3000 lux) light, and 2) were exposed to a 3 h pulse of bright light (3000 lux) alone.ResultsOn the baseline and recovery nights, subjects maintained their usual sleep-wake schedules. On the treatment night, exercise+ bright light or bright light alone were centered at 6 h before their usual wake times, followed by bedtimes 30 min after the treatments. Illumination was 3000 lux during the experimental treatments, 0 lux during the sleep periods, and 50 lux at other times. Sleep was assessed with an Actillume (Ambulatory Monitoring, Inc., Ardsley, NY) wrist monitor to define sleep onset latency (SOL), wakefulness after sleep onset (WASO), and total sleep time. Subjective assessments of SOL, WASO, and insomnia were also gathered each morning. No significant differences in objective or subjective sleep variables were found between treatments.ConclusionsThese data are inconsistent with the general opinion that vigorous exercise shortly before bedtime disturbs sleep.
