Emerging research shows a high prevalence of fatigue and sleep problems among university students. The present study evaluates the effects of regular aerobic exercise on sleep quality and fatigue level among female students (ages 18-26) who reside in dormitories.
This quasi-experimental study involving 67 participants consisted of one experimental group (i.e., assigned aerobic exercise) and one control group (i.e., not assigned aerobic exercise). Participants in the experimental group received three one-hour sessions aerobic exercise weekly ranging from mild to moderate intensity for eight-week. Sleep quality and fatigue level were evaluated using the Pittsburgh Sleep Quality Index (PSQI) and standard Multidimensional Fatigue Inventory (MFI-20), respectively. These variables were assessed at baseline, week four, and week eight of the study.
After four and 8 weeks of the intervention, participants in the aerobic group showed improvement in the score of sleep quality ( < 0.001 and < 0.0001, respectively) and its components (except for sleep duration after 4 weeks intervention). Also, aerobic exercise resulted in a significant reduction of the total score of fatigue and its dimensions in weeks four and eight, compared to the control group ( < 0.001).
Four-week aerobic exercise with mild intensity had no significant effect on sleep duration. Conversely, intensified aerobic exercise for 8 weeks influenced all components of sleep quality.
The study was registered on 6/2/2015 in the Iranian Registry of Clinical Trials (IRCT) with number IRCT201412282324N15.
新出现的研究表明，大学生中疲劳和睡眠问题的发生率很高。本研究评估了规律有氧运动对居住在宿舍的18至26岁女学生睡眠质量和疲劳水平的影响。
这项涉及67名参与者的准实验研究包括一个实验组（即分配有氧运动）和一个对照组（即未分配有氧运动）。实验组的参与者每周接受三次一小时的有氧运动，强度从轻度到中度，为期八周。分别使用匹兹堡睡眠质量指数（PSQI）和标准多维疲劳量表（MFI-20）评估睡眠质量和疲劳水平。这些变量在研究的基线、第四周和第八周进行评估。
干预四周和八周后，有氧运动组参与者的睡眠质量得分（分别为<0.001和<0.0001）及其组成部分（除了四周干预后的睡眠时间）有所改善。此外，与对照组相比，有氧运动在第四周和第八周导致疲劳总分及其维度显著降低（<0.001）。
四周的轻度有氧运动对睡眠时间没有显著影响。相反，八周的强化有氧运动影响了睡眠质量的所有组成部分。
该研究于2015年6月2日在伊朗临床试验注册中心（IRCT）注册，注册号为IRCT201412282324N15。
