Study links physical activity to greater mental flexibility in older adults
University of Illinois at Urbana-Champaign
One day soon, doctors may determine how physically active you are simply by imaging your brain. Physically fit people tend to have larger brain volumes and more intact white matter than their less-fit peers. Now a new study reveals that older adults who regularly engage in moderate to vigorous physical activity have more variable brain activity at rest than those who don't. This variability is associated with better cognitive performance, researchers say.
