Abstract

The purpose of this study was to identify possible differences in strength ratios and neuromuscular performance between high school female and male basketball players, as tested by concentric isokinetic testing using the Blodex® isokinetic system . We recruited high school basketball players, females (N=26) and males (N=27). All participants underwent isokinetic concentric testing of bilateral hamstrings and quadriceps at five speeds (60, 180, 240, 300, 450 degrees per second). Female subjects demonstrated lower hamstrlng/quadriceps ratios than males at 60 and 240 degrees per second. Compared with male subjects, the female subjects took significantly longer to generate maximum hamstring muscle torque during isokinetic testing at all speeds except 450 degrees per second. The results of this study suggest that there are differences between hamstrlng/quadriceps ratios and time to peak torque of the hamstrings by gender. The variable of strength should continue to be investigated in relationship to injuries of the ACL in the female athlete.
