Can eight weeks of stabilization exercise change theamount of knee flexion and anterior shear force?

Abstract

Aim This study aimed to evaluate the effect of eight-week stabilization training on knee flexion and anterior shear force during a single leg drop landing to prevent ACL injury. MethodsThirty basketball athletes were randomly assigned to a training group (n = 15) and a control group (n = 15). Training group performed the Core stability training for 8 weeks, but control group did not perform these exercises. Lower extremity kinetics and kinematics variables during single-leg drop landing were collected by motion analysis and force plate in pre and post-test. Data were analyzed by using mixed ANOVA repeated measure test with significance level of P≤0.05. Results The results showed that the amount of knee flexion significantly increased after conducting the 8 weeks of core stability training (P< 0.05), while there was no significant decrease in anterior shear forces (P> 0.05). Conclusion Based on the results, the core stability training by increasing the core stability can improve the core muscles recruitment during landing. Therefore, it can be concluded that core stability training can reduce the ACL injury risks during the dynamic movements.
