Grip strength can predict lifespan

How strong you can grip may be a better predictor of future health and longevity according to a recent study published in the British Medical Journal. After accounting for age and a wide variety of other factors, such as diet, amount of time being sedentary, and socioeconomic status, researchers found that muscle weakness—defined by a grip-strength measurement of less than 26 kilograms (57 pounds) for men and less than 16 kilograms (35 pounds) for women—was associated with a higher risk of premature death and a higher risk of heart and lung disease, and cancer.

Researchers in Norway found that those who have excellent grip strength in their 80s and 90s are more likely to live in good health into their 100s. The role of skeletal muscle is often underappreciated. It not only controls our body movement; skeletal muscle also stores protein and plays a major role in glucose and lipid metabolism.

Comments from Dr. Thomas: How thorough is your doctor when performing a physical examination? When someone comes to see me for the first time, we measure numerous vital signs, including blood pressure, resting heart rate, body temperature, body mass index, waist-to-height ratio, lung vital capacity, breath hold test, peripheral vascular elasticity, heart-rate variability (autonomic nerve balance), grip strength, and bone density. Grip strength isn’t just an issue that concerns frail adults. Building and maintaining overall strength is important at any age. The sooner you start, the better.
