Question

How does body size and proportions affect grip strength?

Answer 1

Grip strength in old age was significantly associated with larger size during growth (both height and weight) and also later height timing. This implies, as might be expected based on allometry, that larger overall size results in more muscle mass and greater strength.

E.g. After controlling body mass, hand length, palm width, forearm length and wrist circumference significantly correlated with handgrip strength in grip athletes. But thumb length, palm length, MF length, and forearm circumference did not show a significant correlation with handgrip strength.

Hand grip strength is a physiological variable that is affected by a number of factors including age, gender and body size among others. ... Right and left hand grip strength was positively correlated with weight, height and body surface area.
