Sleep is crucial for psychological functioning and daily performance. Both lay and scientific opinion hold that physical activity encourages restorative sleep. However, research on this in adolescence is limited. The aim of the present study was to compare sleep-EEG patterns of vigorous exercisers and controls. Twelve adolescent male football players (14 h of vigorous exercise per week) and 12 controls (1.5 h of vigorous exercise per week) matched for gender, age (about 16 years), and educational level, took part in the study. Sleep-EEG registration was performed following a day without exercise. Sleep-EEG analyses revealed that, compared to controls, the football players showed greater sleep efficiency, shortened sleep onset latency, less awakenings after sleep onset, more stage 4, and less REM sleep. Importantly, this pattern of results emerged following a day without exercise. Moreover, vigorous football players reported better daily performance and displayed less weeknight (Sunday to Thursday) to weekend night (Friday and Saturday nights) variation. Findings suggest that for the football players, vigorous exercise seemed to lead to longer-lasting electrophysiological change in brain activity irrespective of acute bouts of exercise.
睡眠对心理功能和日常表现至关重要。无论是普通大众还是科学界都认为，体育活动有助于恢复性睡眠。然而，目前针对青少年的研究有限。本研究旨在比较剧烈运动者和对照组的睡眠脑电图模式。12 名青少年男性足球运动员（每周进行 14 小时剧烈运动）和 12 名对照组（每周进行 1.5 小时剧烈运动）按性别、年龄（约 16 岁）和教育程度匹配，参与了这项研究。在没有运动的一天进行了睡眠脑电图记录。睡眠脑电图分析显示，与对照组相比，足球运动员的睡眠效率更高，入睡潜伏期更短，入睡后觉醒次数更少，第 4 阶段睡眠更多，快速眼动睡眠更少。重要的是，这种结果模式是在没有运动的一天出现的。此外，剧烈运动的足球运动员报告说日常表现更好，并且工作日（周日至周四）到周末（周五和周六晚上）的变化较小。研究结果表明，对于足球运动员来说，剧烈运动似乎导致大脑活动的电生理变化更持久，而与急性运动无关。
