Abstract:   (107 Views)
Aims: Scapula Dyskinesis (SD) and reduction the strength of glenohumeral External rotator muscles (ER) are shoulder risk factors. While performing high-intensity repetitive throwing movements in overhead athletes can gradually affect the stabilizing mechanisms of the shoulder joint, which are mainly the glenohumeral rotator muscles. This can cause a decrease in the strength of the ER, imbalance of the rotator cuff muscles and SD. Therefore, the purpose of this study was to investigate the effect of an exercise program on SD and the strength of glenohumeral rotator cuff muscles in overhead athletes.
Methods:  The present quazi experimental study with control group and pre and post-test plan was conducted on 62 female handball players (club-level, 18–25 years old) with SD from 2021 to 2022 in Hamadan city. The Lateral scapular slide test and Hand dynamometers were used to measure SD and the strength of Glenohumeral rotator cuff muscles, respectively. The participants in the intervention group participated in eight weeks of three sessions of exercise program. Data
Were measured before and after the intervention and were analyzed using Mann-Whitney U test.
Findings:  According to this test, there is a significant difference between the strength of ER (p<0.001) in the intervention and control groups after exercises, So that the strength of ER and the strength of External rotator muscles to Internal rotator muscles ratio (ER:IR) (p< 0.001) has increased after exercises. Also, SD (p= 0.013) after exercises has decreased significantly.
Conclusion: Exercises program can increase the strength of ER and ER:IR ratio, and improves SD in overhead athletes.
