The effect of sex and fatigue on lower limb kinematics, kinetics, and muscle activity during unanticipated side‐step cutting

Our results suggest that sex differences, especially larger IGRF in a fatigue state combined with less hip flexion angle, lead to women having a higher risk for anterior cruciate ligament (ACL) injury. These findings may contribute to understanding the underlying mechanism of injury and development of preventive exercises against ACL injury.
