Abstract

Purpose:
ACL injury is one of the most common non-contact injuries among women athletes. ACL injury prevention is especially important with the purpose of decreasing risk factors. The results indicate that during landing, there is a lot of pressure on lower limb joints. The purpose of the present study was to investigate the Effect of 8 weeks of theraband training on ACL injury Risk Factors in Single-Leg Drop and double leg landing.
Methods:
In this study, 26 female amateur athletes with a mean age (25.3±3.6) years, height (162.2±3.8) cm, weight (59.9± 5.9) kg were purposefully and accessibly selected and randomly divided into two experimental group (n=13) and control (n=13). The experimental group performed their exercises for 8 weeks, three sessions per week and 60 minutes per session, and the subjects in the control group continued did not exercise. Single-Leg Drop and double leg landing tests were taken from the two groups of subjects before and after 8 weeks of training. In order to measure the risk factors of ACl injury (knee valgus, range of knee flexion and hip) in Single-Leg Drop and double leg landing, analytical software kinovea (8.27) was used. In order to analyze the data, Mixed Repeated Measures ANOVA was used at a significance level of p≤0.05 using SPSS software, version 24.
Results:
The results of study showed that after eight weeks, a significant improvement in decreasing the amount of knee valgus and increasing the range of motion of the hip flexion Single-Leg Drop and double leg landing (p≤0.05) was observed in the experimental group. Also, in the experimental group, a significant improvement was observed in increasing the range of motion of hip flexion in double leg Drobe landing task (p≤0.05), but no significant difference was observed in the range of motion of hip flexion in single leg Drob landing task (P>0.05).
Conclusions:
The results of this study showed that Theraband exercise program during landing movements can improve some kinematic variables of the hip and knee joint and reduce the risk factors of ACL injury in women.
