This study compares the effectiveness of a 12-week moderate exercise training program (METP), performed in the morning versus the evening, on sleep, physical activity, physical fitness, sleepiness, fatigue and health-related quality of life (HRQoL) in overweight and obese patients. Sedentary and inactive overweight/obese adults (n = 36) were included in METP and randomized into two groups: morning group (GM) and evening group (GE). Twenty-eight participants successfully completed METP (3 × 90 min exercise session per week for 12 weeks, completion rates >80%). Sleep, physical activity, and bedtime temperature were measured using accelerometry and infrared tympanic temperature during 3 separate weeks of the study (Week1, Week6, and Week12). Participants also took part in baseline and endpoint assessments including physical fitness as well as subjective physical activity, chronotype, sleep quality, sleepiness, fatigue and HRQoL. METP did not impact objective sleep quality differently between the two groups (morning vs evening). Bedtime and mid-sleep were advanced when METP was done in the morning whereas they were delayed when METP was practiced in the early evening ( = .003). Beside this finding, no valuable differences between the two groups were noted in all the remaining measures. METP resulted in improvements of body composition, cardiorespiratory and muscular endurance, as well as a favorable impact on subjective sleep quality, diurnal sleepiness, fatigue and HRQoL in both groups (all < .05). Evening METP could be an effective alternative for overweight/obese adults when morning METP is not possible.
本研究比较了为期 12 周的中等强度运动训练方案（METP）在早上和晚上进行对超重和肥胖患者睡眠、体力活动、身体适应性、嗜睡、疲劳和健康相关生活质量（HRQoL）的影响。纳入了久坐不动和不活跃的超重/肥胖成年人（n = 36），并将他们随机分为两组：早晨组（GM）和晚上组（GE）。28 名参与者成功完成了 METP（每周 3 次，每次 90 分钟的运动，共 12 周，完成率>80%）。在研究的 3 周内（第 1 周、第 6 周和第 12 周），使用加速度计和红外鼓膜温度测量睡眠、体力活动和就寝时间温度。参与者还参加了基线和终点评估，包括身体适应性以及主观体力活动、昼夜类型、睡眠质量、嗜睡、疲劳和 HRQoL。METP 对两组之间的客观睡眠质量没有不同的影响（早上与晚上）。当 METP 在早上进行时，就寝时间和半夜时间会提前，而当 METP 在傍晚进行时，就寝时间和半夜时间会推迟（ = 0.003）。除了这一发现，在所有其余测量中，两组之间没有明显的差异。METP 导致身体成分、心肺和肌肉耐力的改善，以及对主观睡眠质量、日间嗜睡、疲劳和 HRQoL 的有利影响，两组均有改善（均<0.05）。当早上进行 METP 不可行时，晚上进行 METP 可能是超重/肥胖成年人的有效替代方案。
