How much time do you have left? Here are two simple tests that can predict life expec

Key Points:

• A University at Buffalo study found that greater muscle strength in older women significantly lowers mortality risk, independent of physical activity levels, cardiovascular fitness, and inflammation markers, based on data from 5,000 women aged 63 to 99 over eight years.
• Muscle strength was measured using grip strength and the chair stand test, with every additional 7 kilograms of grip strength linked to a 12% reduction in death risk, and faster chair stand times associated with a 4% decrease in mortality.
• The study highlights that muscle strength is crucial for enabling movement and functional independence in older adults and suggests that strength training should be emphasized alongside aerobic activity in public health guidelines.
• Even women who did not meet recommended physical activity levels benefited from higher muscle strength, underscoring the importance of muscle strengthening exercises for longevity, especially as the population aged 80 and older grows rapidly.
• Experts recommend combining aerobic activity with muscle-strengthening exercises, which can be done safely at home with simple tools like water bottles, and suggest self-monitoring functional ability through tests like the chair stand to maintain muscle health in older age.
