Aging -- Fit Body, Fit Mind

Workouts help preserve mental fitness through aging

An interesting article by Christopher Hertzog and team featured in Scientific American supports physical fitness as a hedge against age-related dementia. One study cited showed how the most physically active women had a 30% lower risk of cognitive decline. In this study walking distance was related to cognition, but walking speed was not. Jennifer Weuve’s research team at Harvard University found a significant relation between energy expended in physical activity and cognition. Other interesting research is cited related to the body’s impact on the brain, giving elders an effective way to stay mentally sharp.
