Muscle Strength Matters for Senior Women Longevity.
University at Buffalo researcher report that among women aged 63 and older, higher muscle strength—as determined by grip strength and chair-stand performance—is linked to a lower risk of death in the following eight years after adjusting for aerobic activity, inflammation, and cardiovascular fitness. More specifically, each 7-kg (~15.42 lbs.) increase in grip strength was associated with a 12% lower death risk, while faster chair-stand times predicted a 4% reduction.
