Simple strength tests linked to longer life in older women
A study of more than 5,000 women aged 63–99 over about eight years found that higher grip strength and better chair-stand performance predicted lower mortality, independent of age, chronic disease, activity, or sedentary behavior. The results suggest muscular strength reflects overall health and longevity, and maintaining strength through resistance training and daily activities—along with good nutrition and sleep—may help preserve independence as people age.
