Given the scapula&rsquo;s key role in force transmission and shoulder stability, this study aimed to investigate the effect of a corrective exercise program on improving shoulder stability in CrossFit athletes.<br> <strong>Methods</strong>: This quasi-experimental study initially enrolled 26 male CrossFit athletes aged 25&ndash;30 years recruited via purposive sampling from local clubs and selected based on predefined eligibility criteria. An a priori power analysis (G*Power software, version 3.1; effect size=0.54, &alpha;=0.05, power=0.80) indicated a minimum of 24 participants; to accommodate approximately 10% attrition, 26 were enrolled and equally allocated to intervention and control groups (13/13). Scapular stability was assessed with the Davis Test pre- and post-intervention. Data normality was examined with the Shapiro&ndash;Wilk test; within-group changes were analyzed using paired t-tests, and between-group effects with analysis of covariance (ANCOVA) (adjusting for pretest values). Two control participants were lost to follow-up; analyses were completed on 24 athletes. All analyses were performed using SPSS software, version 26 (&alpha;=0.05).<br> <strong>Results</strong>: The intervention group showed significant improvements in scapular stability, with Davis test record increasing by 8.4% and power output increasing by 8.4% (P<0.01), while the control group showed no significant changes (P>0.05). Analysis of covariance (ANCOVA) confirmed significant between-group differences in both Davis Test record &nbsp;(adjusted Mean&plusmn;SD: 13.42&plusmn;1.20 vs 12.67&plusmn;1.65; partial &eta;&sup2;=0.205) and power output (adjusted Mean&plusmn;SD: 1138.23&plusmn;98.67 vs 1050.76&plusmn;134.55; partial &eta;&sup2;=0.241; P<0.05), demonstrating the effectiveness of the corrective exercise program.<br> <strong>Conclusion</strong>: The present study demonstrated that the selected corrective exercises can improve scapular function and enhance shoulder stability. This improvement contributes to increased shoulder strength and power, ultimately contributing to the improvment of movement dysfunctions.</div> CrossFit, Scapular movement dysfunction, Scapular stability, Corrective exercises 189 200 http://ptj.uswr.ac.ir/browse.php?a_code=A-10-716-1&slc_lang=en&sid=1 Fariborz Hovanloo f_hovanloo@sbu.ac.ir 0000-0002-8743-6442 Yes Department of Sports Health and Rehabilitation, Faculty of Sports and Health Sciences, Shahid Beheshti University, Tehran, Iran.
