Female soccer players experience a higher rate of anterior cruciate ligament (ACL) injuries than their male counterparts do. Female knee flexion angles are seen to be smaller causing the quadriceps to produce a higher anterior force on the ACL. To combat this, an increase in strength and activation of the posterior chain is required. Therefore, the purpose of this study is to determine the correlations between an overhead deep squat (OHDS), which requires a synergist activation of both the quadriceps and the hamstrings, and a high velocity pivot task (HVPT). It is hypothesized that an athlete who performs an ideal OHDS will also have favorable kinematics during their HVPT performance. For this purpose, 30 female soccer players will perform three repetitions of a controlled OHDS movement and one repetition of an HVPT. Kinematic and kinetic data will be collected during both trials using motion capture technology and force plates. Currently, we are developing and validating a musculoskeletal model to analyze the data using an inverse dynamics workflow and to solve a static optimization problem for accurate joint kinematics, muscle forces, and ACL strain. Finding correlations between the OHDS and HVPT will allow athletes to strengthen their muscles in a controlled environment with the goal that it will translate to a dynamic noncontact movement. Quantifying these deficits could expose female soccer player’s susceptibility to ACL tears before the injury occurs providing medical professionals with a prevention technique.
