Do the exercises performed with a theraband have an effect on knee muscle strength balances?

In the current literature, exercises performed using fitness equipment and body weight have been used in order to decrease the bilateral deficit (BLD) and increase the hamstring-quadriceps (H/Q) ratio. No studies have previously investigated the effect of therabands, which are both portable and practical to be used anywhere, in regard to the BLD and H/Q ratio.

The purpose of this study was to investigate the effect of several 10-week lower extremity exercises performed through therabands on the BLD and H/Q ratio.

Twenty-seven voluntary male soccer players participated in the study. The players were categorized into the control group (CG) (n= 14) and the theraband exercise group (TBG) (n= 13). Theraband exercises for the lower extremity were performed by the soccer players in the TBG for four days every week over a 10-week period. The dominant (D) and non-dominant (ND) leg concentric extension and flexion of the soccer players were determined through an isokinetic dynamometer at 30∘s-1 and 240∘s-1 angular velocities. The data were analyzed through SPSS 24. To determine the difference between the BLD, H/Q ratios, and pre- and post-test of peak torque (PT), the Wilcoxon test was employed.

As a result of the analysis, it was found that the BLD for the TBG decreased, which was statistically significant (p< 0.05), whereas there were no statistically significant differences for the H/Q ratio for both the CG and TBG; the D and ND leg H/Q rate of the TBG at 240∘s-1 angular velocity increased in the post-test.

It was found that the exercises performed with the theraband were extremely efficient at increasing the PT and decreasing the BLD.
