PerspectiveEffects of physical activity on cognition, well-being, and brain: Human interventions

This article provides a review of the human intervention literature that has examined the influence of fitness training on cognition, well-being, brain structure, and brain function. Meta-analyses of this literature, which are reviewed here, suggest robust effects of fitness training on cognition and well-being. Although there are currently few human intervention studies that have examined fitness effects on human brain function and structure, the studies that have been conducted report promising results.
