Investigating the Effects of a Warm-Up Injury Prevention Protocol on Risk Factors for Anterior Cruciate Ligament Injury in Elite Basketball Players

Abstract

Introduction: Athletes involved in sports requiring frequent cutting and pivoting movements are at increased risk of anterior cruciate ligament (ACL) injuries. This study investigates the effectiveness of neuromuscular warm-up exercises, including strength, balance, plyometric, and core stability training, in reducing ACL injury risk.
Materials and Methods: A total of 30 adolescent male basketball players (age = 13-18 years) were randomly assigned to either the control group (n=15; age = 15.66±1.7 years, height = 172.7±9.6 cm, weight = 66.74±11.2 kg) or the neuromuscular training (NMT) group (n=15; age = 14.73±0.70 years, height = 174.0±6.7 cm, weight = 64.79±10.8 kg). The NMT group performed a structured injury prevention warm-up program three times a week for eight weeks before regular basketball training (20 min), while the control group followed their usual basketball practice. Measurements of knee proprioception (including specific motion directions), knee valgus and flexion torque, trunk endurance via the Biering-Sorenson test, and isometric strength of various muscle groups were taken pre- and post-intervention.
Results: Significant improvements in isometric strength were observed in all assessed muscle groups in the NMT group (P<0.05); however, no significant changes were found in knee valgus, flexion torque, trunk endurance, or knee proprioception (P>0.05).
Conclusion: While the NMT protocol significantly improves isometric muscle strength in adolescent male basketball players, it does not show a direct effect on other ACL injury risk factors. Therefore, incorporating NMT into training routines may support strength development but should be combined with other targeted interventions to reduce ACL injury risk more effectively.
