چکیده

The current study aimed to compare the Immediate effect of valgus control feedback and elastic resistance band on kinematic risk factors of anterior cruciate ligament (ACL) injury in female athletes. Thirty-four female athletes from three sports of basketball, volleyball and handball were selected for this study and were randomly divided into two groups: valgus control feedback (n = ۱۷) and valgus control feedback with elastic resistance band (n = ۱۷) groups. Groups followed the immediate intervention for fifteen minutes. Data were analysed by means of ۲ × ۲ repeated measures ANOVA followed by post hoc comparison (Bonferroni) at the significance level of p ≤ ۰.۰۵. A significant group × time interaction and the main effect of time was found for peak knee valgus and flexion angles for both groups and peak hip flexion angle only in valgus control feedback with elastic resistance band group. Valgus control feedback and valgus control feedback with elastic resistance band methods positively reduced the kinematic variables that are considered risk factors for ACL injury. However, the effect sizes (partial eta squared) for the changes in most of the variables were larger for the valgus control feedback with elastic resistance band group. Given the high effect size reported, valgus control feedback with elastic resistance band can be an effective immediate training method to reduce kinematic risk factors of ACL injury in female athletes. Therefore, coaches and athletes are recommended to utilize this exercise for the prevention of ACL injuries.
