Association between physical activity practice and sleep quality of older people in social isolation during the COVID-19 pandemic and Health Guidelines and future studies for the post-COVID period: a systematic review.

Purpose: Physical activity (PA) is considered an alternative to mitigate the negative impacts of the COVID-19 pandemic on the sleep of older adults. The objective was to verify the association between physical activity and the sleep quality of older people in social isolation during the COVID-19 pandemic, to analyze the Health Guidelines, and suggest future studies for the post-COVID period.

Methods: This systematic review followed PRISMA recommendations, and the protocol was registered in PROSPERO (CRD 42023406471). The search for articles occurred in April 2024 in the databases PubMed, Web of Science, SCOPUS, and gray literature. Data were extracted and checked in a Microsoft Excel spreadsheet. The quality assessment was performed using tools from the National Institutes of Health.

Results: In total, 1582 studies were found in the databases, of which nine were included in the analyses. Four studies reported a negative association of reduced levels of PA during the pandemic with sleep quality, while one study showed a positive association of PA with sleep quality. Four studies demonstrated no association.

Conclusions: PA was associated with the sleep quality of older adults during the COVID-19 pandemic and reduced levels of PA during this period demonstrated a negative association with sleep quality. Practice of PA is recommended for this post-COVID scenario, as a measure to reduce social isolation and its negative effects and improve the quality of sleep in older adults.
