Abstract

Purpose: It has still not been made clear what effects the audio inputs from the environment may have on the muscle strength on people who spend long periods of their lives with hearing loss. The purpose is to evaluate shoulder muscle strength and endurance of deaf basketball (DB) athletes and to compare them with healty basketball (HB) athletes..
Methods: Study was carried out with a total of 26 athletes including 13 people in DB group and 13 people in HB group. Strength of shoulder internal rotator (IR) and external rotator (ER) muscles were measured using an isokinetic dynamometer.
Results: According to isokinetic test results, there was not a difference between two groups on either dominant or nondominant side in terms of ER and IR Nm/kg (p>0.05). ER/IR ratio was found to be different between two groups (p<0.05). Strength parameters of dominant extremities of athletes in both groups were found to be higher than nondominant extremity.
Conclusions: As a result, IR and ER muscle strengths were similar in two groups, both groups were at risk for musculoskeletal injuries in terms of ER/IR ratio. It was thought that eliminating muscular imbalance between IR and ER muscles by adding ER strengthening exercises to training programs of athletes could reduce risk of injury. The dominant extremity was found to be stronger in both groups. In our opinion, symmetrical movement patterns will positively affect performance on dominant extremity.
