Biomechanics of athlete movement: kinematic analysis and injury prevention

Abstract

 Anterior cruciate ligament (ACL) injuries are prevalent and movement patterns linked to an increased risk of ACL damage can be seen in youngsters under the age of 10. Though the processes underlying these programs are mostly unclear, prevention systems have been demonstrated to lower rates of injury. Biomechanical alterations following injury prevention programs in children have not been extensively studied. In this study, we examine the manner in which modifications in bio-mechanical risk variables for an ACL injury in preadolescent female soccer players are affected by the F-MARC 11+ injury-preventing warm-up program. Our hypothesis was that training would enhance peak knee valgus moment (PKVM), the key risk factor for ACL injuries. Other kinematic and kinetic factors connected to ACL injury were also investigated. An intervention group and a control group were created from a total of 62 athletes who were recruited from soccer teams. F-MARC 11+ in-season sessions were attended by the intervention group fifteen times. Motion capture information from the pre and post-season was gathered while doing activities such as double-leg leap, single-leg jump, unanticipated cutting and preplanned cutting. A biomechanical modeling system called OpenSim was used to determine the angles and moments of the lower extremity joints. According to the results of the experiment, during the double-leg leap, athletes in the group that got intervention had a lower PKVM than those in the control group. This study suggests ways to improve injury prevention programs, especially for single-leg and cutting jobs, to reduce other ACL risk factors.
