Abstract
Decreased hamstrings strength relative to quadriceps strength (H:Q) is a potential risk factor for anterior cruciate ligament (ACL) injuries. PURPOSE: To determine the H:Q at varying angular velocities in female collegiate lacrosse athletes. METHODS: Twenty-three female collegiate lacrosse athletes volunteered for this study. Concentric peak torques were utilized to determine H:Q for both legs by isokinetic dynamometry at 60°/s, 180°/s, and 300°/s. RESULTS: There was no significant interaction for H:Q between legs at different angular velocities. There was a significant main effect for angular velocity. CONCLUSION: Hamstrings peak torque relative to quadriceps increases significantly across all angular velocities in female collegiate lacrosse athletes. This may result in lower ACL injury risk as higher velocities more closely mimic sporting activities.
