Young Adult Fitness Protects the Brain
Physical fitness in young adulthood might mean better brain function in later life, a study suggests. Among more than 2,700 people ages 18 to 30 who took treadmill tests in 1985–86, researchers found that having good fitness as a young adult was linked to better scores on tests of memory and coordination 25 years later. For example, every minute a young adult spent on the treadmill translated to 0.12 more words recalled from a list in middle age. The cause isn’t completely understood, but researchers say poor fitness may directly damage the brain or physical fitness might improve the brain’s blood flow.
