Background: Feedback as intervention strategy seems promising for altering potential risk factors for anterior cruciate ligament (ACL) injuries. However, little information is available regarding whether feedback may be effective in male athletes during a drop vertical jump (DVJ). Objective: To determine the effect of video feedback on (potential) biomechanical risk factors for ACL injury in male athletes. Design: Randomized controlled clinical trial. Participants: Eighteen male, recreational athletes. Intervention: Subjects were randomized to the intervention (IG) (n = 9) or the control group (CG) (n = 9). All subjects had to perform 15 DVJs per session. The IG received video feedback during two intervention sessions. Main outcome measures: 3D kinematic and kinetic data at peak knee valgus torque were collected. Learning effect expressed by percentage overlap of expert versus subject trial was collected as well. Results: The hip flexion angle and range were higher in the IG at post-test in comparison with the CG, controlled for the pre-test. From pre- to post-test the IG increased their hip flexion angle and range and decreased their knee flexion torque. The IG showed different (greater) slopes on the percentage overlap during the first and second session in comparison with the CG. The IG increased their percentage overlap more than the CG from the start of the first to the end of second session and from the start to the end of second session. Conclusions: Video feedback overlay seems to be effective to reduce potential biomechanical risk factors in male team-sport athletes. As a result of the video feedback overlay, the subject increased their percentage overlap with the expert.
