Grip strength

DEGriffkraft

Grip strength is the maximal force generated when squeezing a dynamometer and serves as a low-cost proxy for whole-body muscular function. In the 17-country PURE cohort (Leong et al., Lancet 2015; ~140,000 adults), each 5 kg decrement in grip strength predicted roughly a 16% increase in all-cause mortality, outperforming systolic blood pressure as a mortality predictor. It correlates with neuromuscular health, nutritional status, and recovery capacity, making it one of the most validated biomarkers of biological aging.
