Abstract

The purpose of this study was to identify the effects of posterior pulling perturbation applied to the upper or lower trunk on variables associated with anterior cruciate ligament (ACL) loading during landing. Thirty-eight participants performed double-leg vertical jumps with and without posterior pulling perturbation applied to the upper/lower trunk shortly after the peak jump height. Perturbation resulted in significantly greater impact forces, smaller knee flexion angles, and greater knee extension and adduction moments compared to no perturbation. Upper trunk perturbation resulted in smaller trunk flexion angles than the lower trunk perturbation location. Mid-flight posterior pulling perturbation applied to upper and lower trunks increased ACL loading variables during landing. Posterior pulling perturbation or anterior pushing perturbation might be involved in training to decrease ACL injury risk.
