The Exercise Advantage
“People in their 70s that participated in more physical exercise, including walking several times a week, had less brain shrinkage and other signs of aging in the brain than those that were less physically active,” says study author Alan J. Gow, Ph.D.
Surprisingly, the study showed that participating in mentally and socially stimulating activities, such as visiting family and friends, reading or even learning a new language, did little to ward off the symptoms of an aging brain. Study participants will undergo a second MRI scan at age 76, and researchers plan to compare the two scans to see if the links between exercise and better brain health hold up.
