Grip Strength Predicts Women's Longevity
A major cohort study found that grip strength is linked to longer life expectancy in women over 60, regardless of their activity level or overall fitness. The research positions grip strength as a powerful marker of general muscle health and successful aging. Men's Health UK separately published a comprehensive guide on increasing absolute strength, emphasizing the integration of endurance, hypertrophy, and maximal strength training.
- The study, published in *JAMA Network Open*, followed participants for a mean of 8.3 years and found that for each one standard deviation increase in grip strength, there was a 12% reduction in all-cause mortality risk. - Grip strength is a key diagnostic marker for sarcopenia, the age-related progressive loss of muscle mass and function. The European Working Group on Sarcopenia in Older People suggests that a grip strength of less than 16 kg for women may indicate probable sarcopenia. - This measurement is considered a more powerful predictor of all-cause and cardiovascular mortality than systolic blood pressure. A landmark 2015 study in *The Lancet* found that for every 5 kg decrease in grip strength, there was a 16% increase in the risk of death from any cause. - Grip strength is typically measured in kilograms or pounds using a handheld dynamometer. For women in their 60s, an average grip strength is approximately 17-22 kg (37-48 lbs). - Beyond mortality, weaker grip strength in older adults is linked to a higher risk of falls, fractures, and developing chronic conditions like hypertension and diabetes. - Simple exercises can help maintain or improve grip strength, such as squeezing a tennis ball, performing wrist curls with light weights, and using rubber bands for finger extension exercises.
