ATHENS, Ohio Men over 60 may be able to increase their strength by as much as 80 percent by performing intense weight training exercises, according to physiologists involved in studies of the health benefits of weight lifting. The researchers also have found that older men gain strength at the same rate as men in their 20s.
In a study of 18 men ages 60 to 75, Ohio University physiologists found that subjects who participated in a 16-week, high-intensity resistence training program on average were 50 percent to 80 percent stronger by the end of the study. None of the participants had engaged in weight lifting prior to the study. Researchers also observed improvements in the seniors' muscle tone, aerobic capacity and cholesterol profile.
These are some of the latest findings from a decades-long examination of the impact of exercise on the health of men and women of all ages. When researchers compared the strength gains of the elderly participants in this study to findings from other studies they've done of college-age men, they found that changes in strength and muscle size were similar in both age groups. The findings were published in a recent issue of the Journal of Gerontology.
"There have been a number of research projects that have come out over the years that suggest there is no age limitation to getting stronger from resistance training," said Robert Staron, co-author of this study and an associate professor of anatomy in the university's College of Osteopathic Medicine. "It's become obvious that it's important to maintain a certain amount of muscle mass as we age."
This new study also suggests that elderly men can handle heavy workloads
over a long period of time. Participants who all were in good health and
closely monitored during testing and training performed leg presses, half
squats and leg extensions twice a week to exercise the lower body. When the
men began the study, they were able to leg press about 375 pounds on
