The Relationship Between Physical Activity and Cognitive Function in Older Adults: A Meta-Analysis of Longitudinal Studies
Abstract
Maintaining cognitive function is essential for healthy aging, and physical activity has been suggested as a modifiable lifestyle factor that may promote cognitive health in older adults. This meta-analysis of longitudinal studies examines the relationship between physical activity and cognitive function over time. Drawing from a comprehensive review of the literature, the meta-analysis synthesizes effect sizes from longitudinal studies that assess the association between various forms of physical activity (e.g., aerobic exercise, resistance training, leisure-time physical activity) and cognitive outcomes, including measures of memory, executive function, and processing speed. Additionally, it explores potential moderators of this relationship, such as age, sex, duration and intensity of physical activity, and baseline cognitive status, to better understand the complex interplay between physical activity and cognitive function in older adults.
