Poor sleep quality lessens general health quality and is related to physical and mental problems. Moreover, fatigue is one of the foremost common complaints in medical care and plays a role in the decreasing quality of life of the older population. For these reasons, the objective of this study was to examine the effect of high- and moderate-intensity interval training programs (HIIT vs. MIIT)-both consisting of twelve weeks of TRX training-on the sleep quality and fatigue levels of the elderly. A randomized controlled clinical trial (NCT03404830) was conducted. A total of 82 subjects were randomized to either a HIIT group (n = 28) that performed a main squat activity with a suspension system, comprising four four-minute intervals between 90-95% of the maximum heart rate (HR), an MIIT group (n = 27) with an intensity of 70% of the maximum HR, and a control group (CG) (n = 27) that continued their daily lifestyle. The two exercise groups trained twice a week for 12 weeks, with each session lasting 45 min. Sleep quality was measured using the Pittsburgh sleep quality index (PSQI), and fatigue was assessed using the fatigue severity scale (FSS). Outcomes were measured before the intervention and after the intervention period. Post-intervention sleep quality measurements revealed a statistically significant interaction regarding group × time ( < 0.005) and fatigue ( = 0.002). Specifically, fatigue decreased in the HIIT group between both measurement moments ( = 0.003). In addition, differences were obtained in the post-intervention measure between the HIIT and MIIT groups ( = 0.013) and HIIT and control ( = 0.029). Our analysis indicates that a population of the elderly showed improvements in sleep quality and fatigue after performing a high-intensity intervention using suspension training (TRX), with markedly better results in the HIIT group.
睡眠质量差会降低整体健康质量，并与身心问题有关。此外，疲劳是医疗保健中最常见的抱怨之一，也是导致老年人群生活质量下降的原因之一。基于这些原因，本研究旨在探讨高强度间歇训练（HIIT）与中等强度间歇训练（MIIT）方案（均由 12 周的 TRX 训练组成）对老年人睡眠质量和疲劳水平的影响。进行了一项随机对照临床试验（NCT03404830）。共有 82 名受试者被随机分为 HIIT 组（n=28）、MIIT 组（n=27）和对照组（CG）（n=27）。HIIT 组进行主要深蹲活动，使用悬挂系统，包括四个四分钟的间隔，强度为最大心率的 90-95%；MIIT 组的强度为最大心率的 70%；对照组继续保持日常的生活方式。两组每周训练两次，持续 12 周，每次 45 分钟。使用匹兹堡睡眠质量指数（PSQI）评估睡眠质量，使用疲劳严重程度量表（FSS）评估疲劳程度。在干预前和干预后测量结果。干预后睡眠质量测量结果显示，在组间×时间方面具有统计学意义的交互作用（<0.005）和疲劳（=0.002）。具体来说，在 HIIT 组中，两次测量之间的疲劳都有所减轻（=0.003）。此外，HIIT 组和 MIIT 组（=0.013）以及 HIIT 组和对照组（=0.029）之间在干预后测量值方面也存在差异。我们的分析表明，老年人在进行使用悬挂训练（TRX）的高强度干预后，睡眠质量和疲劳感都有所改善，而 HIIT 组的效果更为显著。
