| Abstract Introduction: The shoulder joint is a highly mobile joint that allows a wide range of motion, with this functionality facilitated by the coordinated contractions of the surrounding muscles, especially the rotator cuff muscles. Shoulder impingement syndrome (SIS) is prevalent issue in swimmers, impacting functional balance. This study compares of exercises in land and water in functional balance of swimmers with SIS. Methods: The study population consisted of female swimmers aged 20 to 40 years in Qazvin diagnosed with shoulder impingement syndrome. The sample was chosen through a combination of accessibility and purposive sampling. Using G*Power 3.1.9.2 (University of Dusseldorf, Germany), the required sample size was calculated based on a covariance analysis with 80% statistical power and a significance level of 0.05, resulting in 28 participants. To account for potential dropouts, 30 participants were enrolled.Thirty female swimmers with SIS were randomly assigned to land-based training (LBT, n=15) or water-based training (WBT, n=14) groups. Assessments included, functional balance (Upper Quarter Y-Balance Test) measured pre- and post-intervention. The 24-session programs involved progressive stretching and resistance exercises, with intensity adjusted biweekly using the Borg scale (RPE 9–11). Data were analyzed using ANCOVA followed by Bonferroni post hoc test. Results: The Shapiro–Wilk test confirmed normal data distribution. Pre-intervention one-way ANOVA showed no significant differences between groups (p < 0.05), indicating participant homogeneity.WBT led to greater improvements in pain (ŋ² = 0.94), Y-Balance (ŋ² = 0.89), and functional disability (DASH; ŋ² = 0.31) compared to LBT (p < 0.01). Conclusion: WBT is particularly effective for reducing pain, improving functional disability, and enhancing functional balance in individuals with SIS Conversely, land-based training more effectively improve shoulder . Combining water- and land-based interventions, with careful monitoring of pain, may provide an optimal rehabilitation strategy, accelerating functional recovery, restoring healthy movement patterns, and reducing the risk of reinjury. |
