Brief Summary

Anterior cruciate ligament (ACL) tears are disabling injuries that place a significant burden on the athlete. Roughly 80% of these injuries are linked to a noncontact mechanism, with more than 70% of them occurring while landing from a jump. Female athletes are at higher risk of sustaining a noncontact ACL injury due to the higher number of risk factors that they possess compared to their male counterparts. Due to this statistic, ACL prevention programs have been developed over the past 15 years in attempt to reduce this risk among the female athletic population. These programs have been shown to reduce the rate of noncontact ACL injuries in females by correcting the risk factors associated with them. However, it remains unclear as to whether these positive results are solely due to the program or a higher exercise workload in its participants. The purpose of this study is to evaluate the effectiveness that an ACL prevention program has on modifying at-risk landing mechanics (associated with noncontact ACL injury) compared to a resistance training program of equal workload.

Conditions

ACL; Anterior Cruciate Ligament Injury

Keywords

Effectivness; Neuromuscular Training; Resistance Training; Modification; Anterior Cruciate Ligament Risk Factors; Drop-Jump; Knee Separation; Resistance training program

Outcome Measures

Primary Outcomes (1)

• Change in Knee separation during the Drop Jump Test

  Participants will begin the test by standing on a box, dropping off, landing straight in front of the box, and immediately performing a maximum vertical jump. Following the completion of the three trials, the examiner chooses the trial in which the participant has the highest jump to best represent the participant's jumping ability for video analysis. The following images will be captured as still photographs: (1) pre-landing; (2) land; and (3) takeoff.

  1 week prior to training begins, and 1 week after training finishes.

Secondary Outcomes (1)

• Changes in Vertical Jump Test

  1 week prior to training begins, and 1 week after training finishes
