Weight training improves walking endurance in healthy elderly persons

Article Abstract:

Healthy elderly persons may improve their leg strength and exercise endurance by participating in a weight training program. Researchers compared walking endurance, leg strength, leg muscle mass, and body composition among 24 healthy elderly persons who participated either in a 12-week weight training program or continued with their normal activity levels (the control group). Among the weight training group, walking endurance time increased from 25 minutes to 34 minutes. The maximum weight lifted with the leg flexion machine increased by 65% and with the leg extension machine increased by 29% in the weight training group. Walking endurance time and leg strength measurements did not change in the control group. The weight training group tended to have lower blood pressure and heart rates than the control group. There were no significant changes in any of the body composition measurements or aerobic capacity in either group.
