DON'T WALK, RUN TO THE FOUNTAIN OF YOUTH

STANFORD, Calif. — Regular running slows the effects of aging, according to a new study from the Stanford University School of Medicine that has tracked 500 older runners for more than 20 years. Elderly runners have fewer disabilities, a longer span of active life and are half as likely as aging nonrunners to die early deaths, the research found.

“The study has a very pro-exercise message,” said James Fries, MD, an emeritus professor of medicine at the medical school and the study’s senior author. “If you had to pick one thing to make people healthier as they age, it would be aerobic exercise.” The new findings appear in the Aug. 11 issue of the Archives of Internal Medicine.

Fries was surprised the gap between runners and nonrunners continues to widen even as his subjects entered their ninth decade of life. The effect was probably due to runners’ greater lean body mass and healthier habits in general, he said. “We don’t think this effect can go on forever,” Fries added. “We know that deaths come one to a customer. Eventually we will have a 100 percent mortality rate in both groups.”

But so far, the effect of running on delaying death has also been more dramatic than the scientists expected. Not surprisingly, running has slowed cardiovascular deaths. However, it has also been associated with fewer early deaths from cancer, neurological disease, infections and other causes.
