Healthier Weight Means Stronger Legs for Aging Women

Maintaining a healthy weight in older age may no longer just be about cardiovascular and metabolic health. New research shows that one's weight may also affect leg strength.
Scientists at the University of New Hampshire conducted a study looking at the effects that a woman's weight may have on her legs. This is of particular interest to aging women because stronger legs usually mean greater independence and mobility.
In their experiment, the researchers enrolled 25 women between the ages of 65 and 80. After categorizing the subjects by body mass index (BMI), the scientists looked at leg strength, walking speed and power. Their results showed that women with a more optimal BMI had stronger legs, as reported in the Journal of Electromyography and Kinesiology.
"Being of a normal body weight lets you perform activities of daily living and live on your own longer," said lead author Dain LaRoche, professor of kinesiology.
Between losing weight or exercising to increase leg strength, it may be easier for concerned women to do the latter, according to the researchers, who added that eight to 15 repetitions of weight training exercises should help the muscles.
The study was supported in part by the National Institute on Aging, a division of the National Institutes of Health.
