Recent science suggests that exercise may slow the fraying of telomeres, which are the end caps on your chromosomes that determine aging. Past studies have shown, for instance, that master athletes typically have longer telomeres than sedentary people of the same age, as do older women who often walk or engage in other fairly moderate exercise.
Interestingly, these associations were strongest among people 40 to 65, suggesting that middle age may be a key time to begin or maintain an exercise program if you wish to keep telomeres from shrinking, says Paul Loprinzi, an assistant professor of health and exercise science at the University of Mississippi. However, as Loprinzi pointed out, this study is purely associational, so it cannot show whether exercise actually causes changes in telomere length, only that people who exercise have longer telomeres.
