Have you ever used orthotic therapy to help a runner keep running? You may be giving them a longer life.
After a 20-year study involving close to 1,000 middle-aged adults, researchers found that the running participants were half as likely to have died during the study period, compared with the nonrunners. The runners experienced less disability, too.
In fact, the difference in mortality rates was phenomenal. During the study, about 34 percent of the nonrunners had died by age 70 or so, compared with just 15 percent of the runners -- even though the groups were of similar age, weight, and health status.
The authors concluded that participation in long-term running and other vigorous exercise among older adults is associated with less disability and lower mortality after over two decades of follow-up.
