Background and Aims: Biomechanical and neuromuscular risk factors such as dynamic knee valgus, static and dynamic balance are contributing to anterior cruciate ligament (ACL) injuries in young soccer players. This study aimed to investigate the effect of the “Knee Control” injury prevention program on dynamic knee valgus, static and dynamic balance in young male soccer players with dynamic knee valgus deficiency.
Methods: The present study was quasi-experimental and practical. At first 156 players were assessed and finally, 48 soccer players with dynamic valgus were recruited to participate in this study. Then, the players were randomly assigned to the intervention group (n=24 players, age= 12.70±0.62 years, height= 1.52±0.07 m, weight= 48.87±6.67 kg, BMI= 21.10±2.18 kg/m2) or control group (n=24 players, age= 12.58±0.65 years, height= 1.52±0.08 m, weight= 50.45±6.79 kg, BMI= 21.88±2.92 kg/m2). Drop-jump test, Bass Stick test and Y Balance test were used to measure dynamic knee valgus angle, static and dynamic balance, respectively. The intervention group used the Knee Control program as a warm-up for 8 weeks while the control group performed its routine warm-up during this time. ANCOVA and paired-samples t-test were used to evaluate changes.
Results: The results obtained in the intervention group in post-test in comparison with pre-test showed that there was a significant reduction in knee valgus angle (P=0.001) and there were significant enhancements in static (P=0.001) and dynamic balance (P=0.001) but there were no significant differences in the control group in knee valgus angle, static and dynamic balance (P>0.05) after 8 weeks. Moreover, the results showed significant differences between groups in knee valgus angle (P=0.001), static (P=0.001) and dynamic balance (P=0.002).
Conclusion: This study demonstrated that the “Knee Control” injury prevention program was effective in reducing dynamic knee valgus angle and improving static and dynamic balance in young soccer players. Thus, it seems that this program can reduce the risk of ACL injuries in young male soccer players.
