title: Military movement training program improves jump-landing mechanics associated with anterior cruciate ligament injury risk.
abstract: As part of the physical education program at the United States Military Academy, all cadets complete a movement training course designed to develop skills and improve performance in military-related physical tasks as well as obstacle navigation. The purpose of this study was to determine if completion of this course would also result in changes in jump-landing technique that reduce the risk of anterior cruciate ligament (ACL) injury. Analysis of landing mechanics on a two-footed jump landing from a height of 30 cm with a three-dimensional motion capture system synchronized with two force plates revealed both positive and negative changes. Video assessment using the Landing Error Scoring System (LESS) revealed an overall improved landing technique (p=.001) when compared to baseline assessments. The studied military movement course appears to elicit mixed but overall improved lower extremity jump-landing mechanics associated with risk for ACL injury.
