Jump-landing biomechanics following a 4-week real-time feedback intervention and retention.

摘要: Abstract Background Poor neuromuscular control can increase the risk of anterior cruciate ligament (ACL) injury. Landing with decreased knee and hip flexion may lower extremity Feedback interventions have demonstrated changes in jump–landing biomechanics. Traditional feedback (TF), provided after task completion, includes critical factors to focus on during jump–landing. Real-time (RTF), while completing task, be superior for improving This investigation evaluated effect RTF + TF compared TF a group changing biomechanics following 4-week intervention 1-week no retention. Methods Participants completed 12 sessions over 4 weeks. At each session, participants performed 6 sets jumps off 30 cm box. were or set jumps. tested at baseline, immediately The was two time points 4 weeks apart. Findings Acquisition analysis: groups greater change peak angles intervention. decrease vertical ground reaction force group. No significant differences observed between retention analysis. Interpretation study provides evidence acquisition biomechanical Future research should further investigate changes, optimal length transfer learned similar athletic tasks.
