Vigorous Exercise with Age
Exercise with Age
People who sustain a highly active lifestyle gain less weight as they age.
A new study by Paul Williams of Berkeley Lab has found that maintaining a vigorously active lifestyle can help offset gaining weight with age. The data comes from the National Runners' Health Study which conducted 20 years of research on 120,000 runners. The runners maintained a weekly mileage over the course of 7 years. The men and women who ran over 30 miles per week gained half the weight of others that ran less than 15 miles.
Men who ran less than 15 miles per week annually gained 1.4 pounds, men who ran between 15 and 30 miles gained 0.8 pounds, and men who ran more than 30 miles gained 0.6 pounds. The trend was the same in women with 2 pounds for 15 miles, 1.4 pounds for 15-30 miles, and 0.8 pounds for more than 30 miles per week annually. Runners also gained fewer inches around their waistline and women had fewer inches added to their hips.
The relatively small differences in weight gain within the study are difficult to correlate to dramatic differences in health outcomes since there is no comparison to a non-running, non-exercise group. However, the study illustrates that regular exercise can reduce the risk of many chronic diseases by helping to prevent the onset of weight gain with age.
