目的：本研究的目的是比较急性早晨或晚上锻炼对具有两种主观失眠症状的个体夜间睡眠的影响：入睡困难 (DIS) 和早醒 (EMA)，分别针对前半夜和后半夜。方法：患有 DIS (N = 15) 或 EMA (N = 15) 的老年个体（55-65 岁）以及年龄和性别匹配的对照组 (N = 13) 参与在这项非随机交叉研究中。参与者按照基线条件被分配到两种运动条件（早上运动和晚上运动），条件之间有两周的时间间隔。在每种运动条件下进行一次有氧台阶运动。进行夜间多导睡眠图以评估客观睡眠质量。获得患者夜间睡眠变化量表评分的总体印象，以主观评估不同组。结果：剧烈体育锻炼并不能改善主观睡眠质量。晨练减少了整个晚上的换班次数。所有组的觉醒指数和阶段转换次数均有所下降，尤其是在后半夜。此外，早晨锻炼减少了 DIS 组后半夜清醒阶段的数量，但 EMA 组却没有。结论：剧烈的早晨锻炼可以改善难以入睡的个体的夜间睡眠质量，尤其是在后半夜。 (C) 2017 Elsevier B.V. 保留所有权利。
Objectives: The aims of this study were to compare the effects of acute morning or evening exercise on nocturnal sleep in individuals with two subjective insomnia symptoms: difficulty in initiating sleep (DIS), and early morning awakening (EMA), separately for the first vs the second halves of the night.Methods: Older individuals (55-65 years old) with DIS (N = 15) or EMA (N = 15) and age- and sex matched controls (N = 13) participated in this non-randomized crossover study. Participants were assigned to two exercise conditions (morning exercise and evening exercise) in counterbalanced order following the baseline condition with a two-week interval between conditions. A single session of aerobic step exercise was performed during each exercise condition. Nocturnal polysomnography was carried out to evaluate objective sleep quality. Patient global impression of change scale scores for nocturnal sleep were obtained to subjectively evaluate the different groups.Results: Acute physical exercise did not improve subjective sleep quality. Morning exercise decreased the number of stage shifts over the whole night. The arousal index and the number of stage shifts were decreased especially during the second half of the night in all groups. Furthermore, morning exercise decreased the number of wake stages during the second half of the night in the DIS group, but not in the EMA group.Conclusions: Acute morning exercise can improve nocturnal sleep quality in individuals with difficulty initiating sleep, especially during the later part of the night.
