Abstract

Background

The beneficial effects of physical activity on sleep quality in older adults are well-established. However, determining the optimal dose of physical activity remains unclear. This study aimed to investigate the dose-response relationship between physical activity and sleep quality in older adults.

Methods

A comprehensive search was conducted across six electronic databases from inception to May 2024. Included were randomized controlled trials assessing the impact of physical activity on sleep quality in older adults. Changes in sleep quality scores were analyzed using a normal-likelihood model with an identity link function.

Results

Fifty-one studies involving 5890 participants met the inclusion criteria. The dose-response relationship was best described by a “J" shaped curve. The minimum significant dose was 195 metabolic equivalents of tasks (METs)-min/week (Hedges'g = −0.39, SE: 0.27, 95%CrI: −0.82 to 0), with the optimum dose identified as 440 METs-min/week (Hedges'g = −0.85, SE: 0.26, 95%CrI: −1.24 to −0.37). The tolerated dose was also 820 METs-min/week (Hedges'g = −0.85, SE: 0.26, 95%CrI: −1.24 to −0.37). The optimal dose of 440 METs/min/week consistently improved sleep quality across various physical activities. Additionally, participant characteristics such as age, sex, and exercise intensity may moderate the effects of different physical activities.

Conclusion

This study identified the optimal weekly dose of physical activity to enhance sleep quality in older adults, highlighting the effectiveness of various physical activities. It also explored moderating factors affecting intervention outcomes. These findings provide valuable insights for tailoring personalized physical activity programs in clinical settings.

改善老年人睡眠质量的最佳体育锻炼方式和剂量：贝叶斯剂量反应荟萃分析

背景体育锻炼对老年人睡眠质量的有益影响已得到证实。然而，如何确定体育锻炼的最佳剂量仍不清楚。本研究旨在调查体育锻炼与老年人睡眠质量之间的剂量反应关系。方法从开始到 2024 年 5 月，在六个电子数据库中进行了全面检索。纳入的随机对照试验评估了体育锻炼对老年人睡眠质量的影响。结果有 51 项研究（涉及 5890 名参与者）符合纳入标准。剂量-反应关系最好用 "J "形曲线来描述。最小有效剂量为 195 个代谢当量（METs）-分钟/周（Hedges'g = -0.39，SE：0.27，95%CrI：-0.82 至 0），最佳剂量为 440 个代谢当量-分钟/周（Hedges'g = -0.85，SE：0.26，95%CrI：-1.24 至 -0.37）。耐受剂量也是 820 METs-分钟/周（Hedges'g = -0.85，SE：0.26，95%CrI：-1.24 至 -0.37）。440 兆焦耳/分钟/周的最佳剂量可持续改善各种体育活动的睡眠质量。此外，参与者的年龄、性别和运动强度等特征可能会对不同体育活动的效果产生调节作用。研究还探讨了影响干预结果的调节因素。这些发现为在临床环境中定制个性化的体育活动计划提供了宝贵的见解。

期刊介绍： Sleep Medicine aims to be a journal no one involved in clinical sleep medicine can do without. A journal primarily focussing on the human aspects of sleep, integrating the various disciplines that are involved in sleep medicine: neurology, clinical neurophysiology, internal medicine (particularly pulmonology and cardiology), psychology, psychiatry, sleep technology, pediatrics, neurosurgery, otorhinolaryngology, and dentistry. The journal publishes the following types of articles: Reviews (also intended as a way to bridge the gap between basic sleep research and clinical relevance); Original Research Articles; Full-length articles; Brief communications; Controversies; Case reports; Letters to the Editor; Journal search and commentaries; Book reviews; Meeting announcements; Listing of relevant organisations plus web sites.
