The aim of this study was to investigate the effect of selected TRX exercises on functional stability,proprioception and strength of shoulder joint muscles in athletes with scapular dyskinesis.The present study is a semi-experimental study with pre-test and post-test design.For this purpose,30 male athletes of overhead athletes with scapular dyskinesis were randomly divided into training and control 15 person in each group.Athletes with scapular dyskinesis were identified using a lateral scapular slide test.In the pre-test, the strength of internal and external rotator cuff muscles,functional stability and accuracy of shoulder joint proprioception were evaluated by manual dynamometer tests,upper body functional balance test and imaging method, respectively.The subjects in the training group then performed the selected TRX exercises for 8 weeks and 3 sessions per week.At the end of 8 weeks,all measurements of the pre-test were performed again in the post-test stage.A Two-way analysis of variance was used to statistically analyze the research findings at a significance level of P≤0.05.The results of two-way analysis of variance showed that in the post-test stage, rotational muscle strength(P=0.001),functional stability(P=0.001) and accuracy of shoulder joint proprioception(P=0.001) of the experimental group significantly improved compared to the control group.According to the results of the study, it is According to the improvement in rotational muscle strength, functional stability and accuracy of shoulder joint proprioception in TRX group,it is suggested that the TRX exercises used in the present study can use to improve the disorders caused by scapular dyskinesia in overhead athletes and to prevent possible injuries to the shoulder joint.
