Effects on Sleep Quality of Physical Exercise Programs in Older Adults: A Systematic Review and Meta-Analysis

Abstract

Background: Given the beneficial effects of exercise in different populations and the close relationship between healthy ageing and sleep quality, our objective was to determine if physical exercise delivered through a structured program improves sleep quality in older adults. Methods: Embase, PubMed/MEDLINE, Web of Science, and Cochrane Register of Clinical Trials (CENTRAL) were searched to 15 January 2023. Studies that applied physical exercise programs in older adults were reviewed. Two independent reviewers analysed the studies, extracted the data, and assessed the quality of evidence. Results: Of the 2599 reports returned by the initial search, 13 articles reporting on 2612 patients were included in the data synthesis. The articles used interventions based on yoga (n = 5), multicomponent exercise (n = 3), walking (n = 2), cycling (n = 1), pilates (n = 1), elastic bands (n = 1), and healthy beat acupunch (n = 1). In the intervention group, we found significant improvement in Pittsburgh sleep quality index of −2.49 points (95% CI −3.84 to −1.14) in comparison to the control group (p = 0.0003) and sleep efficiency measured with objective instruments (MD 1.18%, 95% CI 0.86 to 1.50%, p < 0.0001). Conclusion: Our results found that physical exercise programs in older adults improve sleep quality and efficiency measured with objective instruments.

Latent Class Analysis of Sleep in Mild Cognitive Impairment Patients and its Influencing Factors

“…Compared to non-smokers, smokers have shorter sleep duration, longer sleep onset latency, and a higher likelihood of developing sleep apnea [ 41 ]. Previous research has demonstrated that physical activity can serve as an effective non-pharmacological intervention to improve sleep quality [ 42 ]. Findings from a randomized clinical trial indicated that tai chi or regular physical activity significantly enhanced objective sleep efficiency and decreased the duration and frequency of awakenings after sleep onset in patients with insomnia [ 43 ].…”

Study on the Profiles of Sleep Disorders, Associated Factors, and Pathways Among Gynecological Cancer Patients – A Latent Profile Analysis

“…Exercise has long been proven to effectively improve sleep quality. 46 Exercise increases the body’s oxygen consumption and affects the secretion of metabolic products such as inorganic phosphates, regulating individual’s sleep quality. 47 Exercise is beneficial for the structure and function of the brain, especially in the elderly, and the improvement of sleep quality through exercise is the foundation for improving cognitive function.…”

Effects of an educational intervention on frailty status, physical function, physical activity, sleep patterns, and nutritional status of older adults with frailty or pre-frailty: the FRAGSALUD study

“…Moreover, as individuals age, notable changes occur in sleep patterns, including alterations in sleep quality and quantity, such as slow-wave sleep, spindle density, and sleep continuity ( 49 ). However, the existing literature on interventions to enhance sleep in older adults remains limited, with exercise being the primary consideration for potential improvement in sleep quality for this population ( 50 ). Similarly, maintaining adequate nutrition has been shown to improve the sleep quality of older adults ( 51 ).…”
