Muscle Power Boosts Longevity for Seniors

A recent study highlights the critical role of muscle strength in promoting longevity for women aged 60 and older. Research conducted at the University at Buffalo followed over 5,000 women, aged 63 to 99, for an eight-year duration.

The study, published in JAMA Network Open, found a significant association between higher muscle strength and a reduced risk of mortality. Muscle function was objectively measured using grip strength and the speed of performing five unassisted chair sit-to-stands.

Lead author Michael LaMonte stated that muscular strength was linked to lower mortality rates, even when accounting for physical activity, sedentary time, gait speed, and inflammation markers. This research better isolated strength's impact on later-life death.

Interestingly, muscle strength proved important for longevity even for women not meeting the recommended 150 minutes of weekly aerobic activity. LaMonte suggested that resistance training, which can be done with minimal equipment, is a vital component of staying active.

While the study focused on older adults, LaMonte noted that future research could explore the long-term effects of building strength earlier in adulthood for potentially greater longevity benefits. He reiterated the importance of consistent movement, stating, "When we can no longer get out of the chair and move around, we are in trouble."
