Abstract

Objective: This study aimed to evaluate the effect of an eight-week strength training program, focusing on the uninjured side, on improving hip and knee function, enhancing proprioception, and increasing muscle strength in professional basketball players who had undergone anterior cruciate ligament (ACL) reconstruction surgery.

Methodology: The study included 30 professional basketball players, all of whom had undergone ACL reconstruction surgery. Participants were randomly divided into two groups: Experimental Group: Underwent a strength training program targeting the uninjured side. Control Group: Did not undergo this training program. Hip and knee flexion angles, proprioception, and muscle strength were measured before and after the training period. Specialized analytical software and measuring devices were used to collect and analyze the data.

Results: The results showed significant improvements in hip and knee flexion angles, proprioception, and muscle strength in the experimental group compared to the control group. The study demonstrated that contralateral strength training contributes to improved hip and knee mobility by increasing strength, flexibility, stability, and neuromuscular control.

Conclusion: Contralateral strength training is an effective method for improving motor function in athletes recovering from ACL reconstruction surgery. This type of training contributes to improved rehabilitation outcomes, including increased flexibility, proprioceptive ability, and muscle performance.
