Notes
- Abstract:
- ACL injuries are the most frequently and debilitating knee injuries in sport. There exists a large gender disparity with female athletes tearing their ACLs at an alarmingly much higher rate (4-6) times that of their male counterpart. Two jump-landing protocols the drop vertical jump and stop jump have been studied because they represent ACL injury inciting maneuvers. These tasks have been proscribed to represent movements commonly seen in basketball, volleyball, and soccer. However, previous research has only focused on the first landing (initial deceleration) of these jump-landing protocols. The purpose of this study was to compare the differences between the drop vertical jump and stop jump during the second landing of these tasks. Nineteen female collegiate athletes were recruited to participate in this study. Three separate MANOVAs were conducted on the kinematic, kinetic, and electromyography dependent variables for both the drop vertical jump and stop jump. Within each task nine dependent variables were analyzed at initial contact and peak knee flexion. These dependent variables included knee flexion angle at initial contact, hip flexion angle at initial contact, peak knee valgus angle, peak knee extension moment, peak knee valgus moment, peak vertical ground reaction forces, hamstrings to quadriceps activation ratio (Q:H) at initial contact and peak vertical reaction forces, and peak proximal tibial anterior shear force. No significant differences were found for the kinematic, kinetic, and electromyography variables between the two jump-landing tasks. Future studies involving more participants and potentially different variables are needed to see if there are differences between during the second landing of these two jump-landing protocols.
