122 Does the foot grip strength relate to various motor skills with bipedal movements in adolescence?

Abstract

The aim of this study was to investigate the relationships between the foot grip strength and various physical performances in adolescence. Eighty-two boys (height: 1.69 ± 0.06 m; body mass: 59.2 ±10.1 kg; BMI: 20.6 ± 3.9; mean length of both feet: 0.252 ± 0.009 m) aged 14-16 years in junior high school were participated in this study. Foot grip strength significantly correlated to hand grip strength (r = 0.56), sit up (r = 0.25), side step (r = 0.52), 50 m sprint (r = -0.37), standing long jump (r = 0.46) and handball throw (r = 0.50). Furthermore, foot grip strength more strongly correlated to side step and handball throwing, comparing to hand grip strength. These results suggest that foot muscle strength is an important evaluating measurement for muscle function of physical fitness in adolescence.
