Effect of Six Weeks of Plyometric Training with Feedback on Maximum Knee Flexion and Maximum Vertical GRF on Drop Landing Technique of Male Basketball Players With Chronic Ankle Instability
With respect to the prevalence of chronic ankle instability and adverse consequences, such as neuromuscular dysfunction of the proximal joints, the implementation of preventive proceeding in the proximal limb of the ankle is very necessary. Therefore, the present study was done to investigate the effect of six weeks of plyometric training with feedback on maximum knee flexion and maximum vertical GRF on the drop landing technique of male basketball players with chronic ankle instability.
The present study has a quasi-experimental research design. Twenty-four male basketball players with chronic ankle instability participated in this study. After identifying individuals using the Cumberland Ankle Instability Tool, athletes were divided into two experimental groups (n=12) and a control (n=12) group. Evaluation of maximum knee flexion and maximum vertical ground reaction force was conducted using ten cameras and two distinct forces, respectively. The participants in the experimental groups performed plyometric training with feedback for six weeks. After examining the normality of data by the Shapiro-Wilk test, a paired t-test was used to compare differences within groups and an independent t-test was used to compare differences between groups.
The results showed that six weeks of plyometric training with feedback on maximum knee flexion and maximum vertical GRF on drop landing technique of male basketball players with chronic ankle instability significantly increased maximum knee flexion and reduced the maximum vertical GRF (P≤0.05).
Adding plyometric training with feedback to the chronic ankle instability basketball program to prevent subsequent damage later in the proximal limb is recommended.
