Strength Training Extends Women's Lives

The study, led by Michael J. LaMonte, tracked 5,472 women and found that those with the strongest grip strength had a 33% lower risk of death compared to the weakest. Similarly, the women who could complete five unassisted chair stands in the shortest time had a 31% lower mortality risk than the slowest group. These findings remained significant even after researchers accounted for other factors like physical activity levels, sedentary time, walking speed, and inflammation. The benefits of muscle strength on longevity were evident even in women who were not meeting the recommended guidelines for aerobic exercise. For postmenopausal women, the decline in estrogen makes them more susceptible to bone loss, which can lead to osteoporosis. Strength training counteracts this by stimulating bone growth and increasing density, particularly in crucial areas like the hips and spine, thereby reducing the risk of fractures. Resistance training also plays a key role in managing weight and metabolic health after menopause. It helps to build and maintain lean muscle mass, which in turn boosts a declining metabolic rate, helping the body burn more calories even at rest. Beyond bone and muscle, strength training supports cardiovascular health by improving blood pressure and insulin sensitivity, and can reduce the risk of heart attack or stroke. It also strengthens the muscles around joints, which can alleviate pain, improve stability, and lower the risk of falls. The U.S. Centers for Disease Control and Prevention recommends that adults aged 65 and older engage in muscle-strengthening activities at least two days a week. These sessions should target all major muscle groups.
