How many seniors over 65 still jog slowly instead of walk for exercise?
New research reveals jogging has unexpected benefits for older adults. The study examined adults over 65, some who exercised by walking and some by running. According to the researchers, people who run at least 30 minutes three times a week are less likely to suffer from an age-related decline in walking efficiency than those who just walk.
The study examined self-reported older joggers over 65 — those who run for at least 30 minutes each day, three times a week — and self-reported walkers, who walk for 30 minutes each day, three times a week.
Older joggers walked 7-10 percent more efficiently than elderly adults who just walked for exercise.
As a result, they walked with similar metabolic rates to young adults. Researchers are not sure why joggers are more efficient than walkers, but they suspect it may have to do with mitochondria in their cells. Research indicates that vigorous exercise is associated with healthier mitochondria in the muscles.
