Physical exercise programmes to improve insomnia or poor sleep quality in non-hospitalised elderly people: a systematic review and meta-analysis
Abstract
Background: Insomnia, or poor quality of sleep, among older people increasingly affects both physical and psychological health. This study aimed to evaluate the efficacy of physical exercise programs for improving sleep quality in non-hospitalized older adults, via objective methods such as actigraphy and polysomnography.
Methods: A systematic review and meta-analysis was conducted between January 1, 2025 and March 31, 2025 according to the standards of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guide. It has been registered in Prospero with the number CRD420251009838. The following databases were consulted: PubMed, Web of Science, CINAHL Complete and Scopus. The studies included groups of participants with a mean age above 60 years, who presented with sleep problems, insomnia or an interest in improving sleep quality. To assess the quality of the studies, the Rob-2 tool for randomized studies and crossover studies and the critical appraisal of the Joanna Briggs Institute were used.
Results: Seven experimental or quasi-experimental studies with intervention groups and/or controls published in the last decade were analyzed. Interventions included aerobic exercise, resistance training, tai chi, and aquatic activities. The results demonstrated improvements in sleep latency, sleep efficiency, total sleep time, and wake time after sleep onset. Meta-analyses confirmed statistically significant benefits, particularly in terms of sleep latency…
