| Research Abstract |
In the current study two different experiments were performed to examine the effects of trunk stabilization and postural correction on noncontact ACL injury risks. Eighteen and thirty females participated in experiment 1 and 2, respectively. In experiment 1, subjects' trunk postures were corrected during single-leg landing. In experiment 2, subjects participated in 8-week trunk stabilization programs and performed single-leg landing before and after training. Targeted biomechanical variables during single-leg landing were compared before and after each intervention. The results showed that in experiment 1 several targeted biomechanical variables were modified to reduce ACL injury risk, while no such significant changes occurred in the targeted variables in experiment 2. These results indicated that athletes should not only undergo trunk stabilization training but also correct their trunk posture during sharp decelerating tasks to reduce noncontact ACL injury risks.
