Investigation of the Relationship of Hand Size and Lower Arm Girths to Hand Grip Strength as Measured by Selected Hand Dynamometers

This study explored the relationship of certain characteristics of the hand and forearm to hand grip strength as measured by adjustable and nonadjustable types of dynamometers. It was found that the measurements of the length of the hand and fingers and forearm girths were significantly related to hand grip strength. First order partial correlations, with weight held constant, changed the significance of only one of the relationships; the correlation between hand length and grip strength scores registered on the Naragansett hand spring dynamometer. A comparison of the means of the scores obtained on each of the three dynamometers, the Stoelting adjustable dynamometer, the cable tensionmeter, and Naragansett hand spring dynamometer, showed a significant difference only between the cable tensiometer and the Naragansett hand spring dynamometer.
