Sleep disturbance is a common symptom in institutionalized older adults that reduces their quality of life and may contribute to progression of cognitive impairment. While we found that a 7-week combination of resistance training, walking and social activity significantly improved sleep in institutionalized older adults compared with a usual care control group, no one to our knowledge has determined the acute effects of resistance training on same-day sleep in this population. Given the effort required to promote exercise adherence in institutionalized older adults and to obtain a positive training effect, understanding of the acute effects of resistance training on same-day sleep architecture should be elucidated, especially with respect to unintended consequences. This secondary data analysis assessed if resistance training altered the same-day sleep architecture in institutionalized older adults. Forty-three participants (age 81.5 ± 8.1 years, male = 17, female = 26) had two attended overnight polysomnography tests in their rooms for sleep architecture analysis; one polysomnography with same-day resistance training, one without any resistance training. Resistance training consisted of chest and leg press exercises (three sets, eight repetitions, 80% predicted one-repetition maximum). There were no significant changes in sleep architecture between either polysomnography nights; sleep efficiency (P = 0.71), time in non-rapid eye movement stages (P = 0.50), time in rapid eye movement stages (P = 0.14), time awake (P = 0.56), time until sleep onset (P = 0.47), total sleep stage shifts (P = 0.65) or rapid eye movement sleep stage latency (P = 0.57). Our results show no acute same-day effects of resistance training on sleep architecture in institutionalized older adults. Clinical Trial Registration ClinicalTrials.gov Identifier: NCT00888706.
睡眠障碍是机构化老年人群体中常见的症状，会降低他们的生活质量，并可能导致认知障碍的进展。虽然我们发现，与常规护理对照组相比，为期 7 周的阻力训练、散步和社交活动相结合可显著改善机构化老年人群体的睡眠，但据我们所知，目前还没有人确定阻力训练对该人群当天睡眠的急性影响。考虑到需要促进机构化老年人群体的运动依从性并获得积极的训练效果，应该阐明阻力训练对当天睡眠结构的急性影响，特别是要考虑到意外的后果。这项二次数据分析评估了阻力训练是否改变了机构化老年人群体当天的睡眠结构。43 名参与者（年龄 81.5 ± 8.1 岁，男性 17 名，女性 26 名）在房间内进行了两次过夜多导睡眠图测试以进行睡眠结构分析；一次多导睡眠图测试有当天的阻力训练，一次没有任何阻力训练。阻力训练包括胸部和腿部按压练习（三组，八次重复，80%预测一次重复最大）。两次多导睡眠图测试之间的睡眠结构没有明显变化；睡眠效率（P=0.71）、非快速眼动阶段的时间（P=0.50）、快速眼动阶段的时间（P=0.14）、清醒时间（P=0.56）、入睡时间（P=0.47）、总睡眠阶段转移（P=0.65）或快速眼动睡眠阶段潜伏期（P=0.57）。我们的结果表明，在机构化老年人群体中，阻力训练对当天睡眠结构没有急性影响。临床试验注册 临床试验.gov 标识符：NCT00888706。
