- Abstract
- Introduction: Neuromuscular control during high-risk sports tasks is viewed as a primary risk factor in ACL injury. Attention has also been given to the role of the hip as a possible explanation contributing to ACL injury rates. Typically neuromuscular predictors of ACL injury have arisen from lab-based assessments; however it is possible that this approach excludes important components of actual game-play that may contribute directly to injury risk. The current study therefore, examined muscle recruitment patterns (MRP) during game-play and lab-based conditions that included hip musculature, to consider strategies for lower limb control. Methods: Nine female subjects had EMG data recorded continuously during a netball game. At a subsequent session, in the lab, EMG data was also recorded for three landing conditions. Bilateral EMG was collected via telemetry for rectus femoris, biceps femoris, medial hamstring and gluteus medius. Muscle onset relative to initial contact and the subsequent pattern/s of onset for each land, for each subject, were examined. Results and discussion: Results indicate that the average number of MRP across subjects was 3.6 and 5.8 for the game-play and the lab-based conditions, respectively. When muscles crossing the knee joint were examined only, results revealed that the average number of MRP across subjects was 2.1 and 2.4 for the game-play and the lab-based conditions, respectively. Differences exist when comparing game-play and lab-based measures and the role of the hip musculature in affecting lower limb control warrants ongoing investigation in relation to ACL injury risk.
