There is a greater incidence of non-contact anterior cruciate ligament (ACL) injury in female athletes compared to males. The higher rate of ACL injury in female athletes is most likely multifactorial and is influenced by intrinsic and extrinsic risk factors. This study examines the effects of an extrinsic factor — static stretching of the hamstrings on knee biomechanics. Twelve female athletes performed drop vertical jump (DVJ) tasks before and after a hamstrings static stretching protocol. Knee kinematics and kinetics were recorded during the contact phase of the DVJ. The results of this study revealed stretching had no significant effect on knee kinetics or kinematics. Our initial hypothesis that static stretching of the knee flexors would increase the incident of biomechanical ACL injury risk factors was not supported.
