Muscle Strength Tests Predict Longevity in Older Women, Study Finds
A major study led by researchers at the University at Buffalo reveals that muscle strength is a significant predictor of longevity in older women. Analyzing data from over 5,000 women aged 63 to 99 over an eight-year period, the research found that simple strength indicators, such as grip strength and the speed of standing up from a chair, are strongly linked to lower mortality risks. Specifically every 7 kilograms of additional grip strength correlated with a 12% reduction in death risk, while faster chair stand times also improved survival rates. These findings remained robust even after adjusting for physical activity levels, cardiovascular fitness, and inflammation markers. The study, published in JAMA Network Open, highlights that muscle strength offers protective benefits independent of aerobic exercise guidelines. Lead author Michael LaMonte emphasizes that maintaining muscular strength is crucial for healthy aging, enabling basic movements and reducing health risks. This research suggests public health recommendations should place greater emphasis on muscle-strengthening activities for older adults, particularly as the population of women over 80 continues to grow.
