Abstract

Introduction

Resistance training improves sleep quality; however, little is known about the effectiveness of flywheel resistance training (FRT) on sleep. This study evaluates the effect of resistance training (traditional vs. flywheel) on both objective and subjective indicators of sleep quality in older women.

Methods

This is a parallel-group randomized controlled trial involving older women without diagnosed psychiatric disorders or uncontrolled noncommunicable chronic diseases (n = 29). Participants were randomly assigned to a traditional resistance training group (TRT, n = 15), which used weight machines and free weights, or to the FRT group (n = 14), which used a multi-leg iso-inertial device. The study was conducted from May to December 2023 at the Federal University of Viçosa, Brazil. Interventions consisted of two non-consecutive weekly sessions over an eight-week period. Objective sleep quality was assessed using actigraphy, while subjective sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI). Blinding was performed by an external administrator.

Results

Objective sleep analysis revealed no significant changes. Both groups showed a reduction in global PSQI scores, with greater improvement observed in the FRT group. Regarding the PSQI components, significant improvement in subjective sleep quality was found in both groups, with superior results in the TRT group. The use of sleep medications decreased in both groups, and daytime dysfunction improved in the FRT group.

Conclusion

Eight weeks of intervention did not affect objective sleep measures but improved subjective sleep quality, particularly in the FRT group.

飞轮阻力训练对老年妇女睡眠质量的影响：一项随机对照试验

抗阻训练提高睡眠质量；然而，人们对飞轮阻力训练（FRT）对睡眠的影响知之甚少。本研究评估了阻力训练（传统与飞轮）对老年妇女睡眠质量的客观和主观指标的影响。方法：这是一项平行组随机对照试验，涉及无诊断精神疾病或未控制的非传染性慢性疾病的老年妇女（n = 29）。参与者被随机分配到传统阻力训练组（TRT, n = 15）和FRT组（n = 14），前者使用举重器械和自由重量，后者使用多腿等惯性装置。该研究于2023年5月至12月在巴西维萨罗萨联邦大学进行。干预措施包括两个非连续的每周会议，为期八周。客观睡眠质量采用活动描记法评估，主观睡眠质量采用匹兹堡睡眠质量指数（PSQI）测量。盲法由外部管理员执行。结果客观睡眠分析显示无明显变化。两组总体PSQI评分均有所下降，FRT组改善更大。在PSQI成分方面，两组主观睡眠质量均有显著改善，其中TRT组效果更佳。两组睡眠药物的使用都有所减少，FRT组白天功能障碍有所改善。结论8周的干预没有影响客观睡眠测量，但改善了主观睡眠质量，特别是在FRT组。
