What does this research mean for the field?

In older adults, exercise is associated with improved sleep quality and cognitive performance, suggesting that sleep may act as a mediating behavioral pathway for the cognitive benefits of exercise. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Synthesize evidence on the relationships between physical exercise, sleep, and cognitive performance in adults aged 60 and older, with an emphasis on sleep as a potential mediator or moderator.

Implication

Structured review reveals exercise improves sleep and cognitive performance in older adults, suggesting sleep quality may mediate exercise-induced brain health benefits.

Key Points

Synthesize evidence on the relationships between physical exercise, sleep, and cognitive performance in adults aged 60 and older, with an emphasis on sleep as a potential mediator or moderator.
Searched PubMed/MEDLINE, EMBASE, Cochrane Library, Scopus, Web of Science, and Google Scholar for studies published between 2015 and 2025.
Identified 12 eligible studies—including randomized controlled trials, non-randomized interventions, and observational studies—evaluating structured exercise or habitual physical activity with both sleep and cognitive endpoints in adults aged ≥60 years.
Moderate-intensity aerobic exercise, multicomponent training, and mind–body interventions were consistently linked to enhanced sleep quality and the preservation or improvement of cognitive function.
Multiple studies identified sleep quality and sleep efficiency as potential mediators or moderators of cognitive gains, though methodological heterogeneity across interventions and outcome tools prevented definitive causal conclusions.
