| Abstract |
| Introduction: Volleyball players are at risk of anterior cruciate ligament (ACL) injuries due to frequent jumping and landing. Maintaining proper motor control and reducing landing errors play a crucial role in injury prevention and enhancing athletic performance. Therefore, the aim of this study was to investigate whether an eight-week injury prevention and performance enhancement protocol affects landing errors, dynamic balance, and motor performance in volleyball players at risk of ACL injury. Methods: This study employed a semi-experimental design with an applied approach. The study population consisted of volleyball players at risk of ACL injury. Among them, 30 participants were selected through convenience sampling and simple randomization based on inclusion and exclusion criteria and assigned to experimental (n=15) and control (n=15) groups. Landing errors were assessed using the LESS system, dynamic balance with the Y-Balance test, and motor performance with the Davis test. The experimental group performed the eight-week protocol, three 45-minute sessions per week under the supervision of the researcher, while the control group only participated in measurement sessions. Data were analyzed using ANCOVA at a significance level of 0.05 with SPSS version 22. Results: The results indicated that after the intervention, landing errors, dynamic balance, and motor performance significantly improved in the experimental group, with higher mean scores compared to the control group (P≤0.05). Conclusion: Targeted injury prevention and performance enhancement exercises can serve as an effective strategy to reduce ACL risk and improve motor abilities in athletes and can be applied by coaches and players. |
