Cognitive Functions Improved by Exercise

Researchers combed the medical literature for the best trials comparing the effect of exercise vs no exercise on four “domains,” or types of cognitive ability: executive function (planning and prioritizing), memory, language ability, and visual-spatial ability.

They found that, across 11 high-quality studies, exercise improved cognitive function in each domain. The greatest effect was in language ability, followed in order by executive function, memory, and visuospatial ability.
