Grip strength—the force exerted when you grasp or squeeze—extends beyond mere hand function and powerlifting movements; it’s a significant indicator of overall health and longevity. Research has consistently linked grip strength to various health outcomes, making it a valuable metric in medical assessments.
Grip Strength and Mortality
A notable study published in The American Journal of Medicine found that decreased grip strength in middle-aged and elderly individuals correlates with higher all-cause mortality. This suggests that grip strength can serve as a predictor of life expectancy.
Cardiovascular Health
Grip strength has been associated with cardiovascular health. A study highlighted by Harvard Health revealed that each 11-pound decrease in grip strength is linked to a 16% higher risk of dying from any cause and a 17% higher risk of dying from heart disease.
Muscle Mass and Sarcopenia
Hand grip strength (HGS) serves as a fundamental metric in assessing muscle function and overall physical capability, particularly relevant to the aging population. HGS holds an important connection to sarcopenia, which encompasses the age-related decline in muscle mass, strength, and function.

Functional Decline and Disability
Weaker grip strength has been linked to increased risk of physical disabilities and decreased physical function in older adults. Studies have shown that low levels of muscle strength are correlated with poor physical performance and higher risk of physical disability.
Cognitive Health
Emerging research suggests a relationship between grip strength and cognitive function. A study in BMC Medicine found associations between grip strength, brain structure, and mental health, indicating that lower grip strength may be linked to psychiatric illness and neurodegeneration in older adults.
Measuring Grip Strength
Grip strength is typically measured using a hand dynamometer, which quantifies the maximum force exerted by the hand. This simple, non-invasive test provides valuable insights into an individual’s muscle function and overall health status.
Improving Grip Strength
Enhancing grip strength can be achieved through specific exercises, such as dead hangs, farmer’s carries, and hand grippers. Regular strength training not only improves grip but also contributes to overall muscle health, potentially mitigating some of the risks associated with low grip strength.
In conclusion, grip strength is a robust indicator of overall health, encompassing aspects of mortality risk, cardiovascular health, muscle mass, functional ability, and cognitive function. Incorporating grip strength assessments into routine health evaluations can provide valuable insights and aid in early detection of potential health issues.
