Grip Strength Predicts Healthy Aging
New evidence suggests that grip strength is a key indicator of healthy aging, with stronger grip associated with lower risk of obesity complications and early death. The research highlights grip strength as a simple but powerful biomarker for overall health and longevity in older adults.
Grip strength is measured with a device called a hand dynamometer, which a person squeezes with their full force. This simple test is a reliable predictor of overall muscle strength, muscle mass, and bone mineral density. For decades, medical professionals have used this measurement to help identify sarcopenia, the age-related decline in muscle mass and strength. A weak grip strength is defined as less than 26 kg (57 pounds) for men and less than 16 kg (35 pounds) for women. Research has linked a decline in grip strength to a higher risk for a range of health issues, including heart disease, Type 2 diabetes, and certain cancers. It can also predict the likelihood of post-surgical complications and recovery time. Studies have found that grip strength is a stronger predictor of mortality and cardiovascular events than systolic blood pressure. For each 5kg decrease in grip strength, there is an associated 16% higher risk of all-cause mortality. This is because grip strength reflects vascular health and the body's overall ability to recover from illness. Grip strength typically peaks between the ages of 25 and 39 and then gradually declines. For men aged 25-29, an average grip strength is around 49.7 kg (109 lb), while for women in the same age range, it's about 29.7 kg (65 lb). Simple exercises can help maintain or improve grip strength. Activities like squeezing a tennis ball, wringing out a wet towel, or carrying weights can work the necessary muscle groups in the hands and forearms. Other beneficial exercises include knitting, playing with clay, and performing simple hand stretches.
