Abstract

The purpose of this study was to investigate the dominant and nondominant leg hamstring/quadriceps relationship at three different speeds of movement using professional soccer players who were beginning their pre-season training. Each subject was tested on bilateral concentric knee flexion/extension using a Cybex NORM isokinetic dynamometer at speeds of 60, 180, and 300 o/s. Data were analyzed using descriptive statistics and a repeated measures analysis of variance (p < .05). The results of the study indicated significant differences between dominant and non-dominant legs. The nondominant leg recorded greater H/Q values than the dominant leg which could indicate less quadriceps strength or greater hamstring strength in this leg.
