Abstract
Aims: Shoulder impingement syndrome (SIS) is a prevalent issue in swimmers, impacting pain, stability, and motor control. This study compares the effects of various training environments on these outcomes in swimmers with SIS.
Method: 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 pain (VAS), stability (Upper Quarter Y-Balance Test), functional disability (DASH), and proprioception (JPS error), 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.
Findings: 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 (all p < 0.01). However, LBT showed superior proprioception with smaller joint position errors in internal rotation, external rotation, and abduction (all p < 0.05).
Conclusion: WBT effectively reduces pain and disability and enhances stability, while LBT improve proprioception, and combining both approaches may optimize overall rehabilitation and functional recovery in SIS.
