Abstract
INTRODUCTION: Beach tennis (BT) combines elements of tennis, volleyball, and badminton, attracting a diverse global following. Despite its popularity, research on its link to shoulder injuries remains limited. This study investigates shoulder characteristics among BT athletes, volleyball players, and tennis athletes to identify potential differences and inform injury prevention strategies. METHODS: A cross-sectional analysis was performed to assess shoulder range of motion (ROM) and rotator cuff strength in 65 athletes using an online questionnaire and biomechanical assessments. RESULTS: Volleyball players demonstrated superior shoulder ROM compared to tennis and BT athletes, while tennis players exhibited a greater difference in internal rotation between sides. Additionally, volleyball athletes displayed greater external rotation strength on the dominant side than tennis players, with BT athletes also exhibiting significant strength advantages. CONCLUSION: These findings emphasise the distinct demands of BT and highlight the need for tailored interventions to optimise performance and minimise injury risks. Customised training and injury prevention approaches are warranted.
