THE INFLUENCE OF TRAINING IN SCAPULAR DYSKINESIA OF VOLLEYBALL PLAYERS: A PROSPECTIVE STUDY

Introduction: In the throwing motion, the balance of scapulothoracic rhythm plays a key role in the efficiency of the Sporting gesture. Scapular diskinesis is commonly associated to specific injuries of the throwing shoulder. Among the causes of scapular dyskinesia, muscle fatigue is often reported due to overuse of the periescapular muscles. Objective: To evaluate the influence of training in the presence of scapular dyskinesis in volleyball athletes. Methods: This is a prospective cohort study in which twelve female athletes practicing volleyball, who had no previous surgeries on the shoulders and practicing at least 10 hours of weekly workouts were evaluated. Assessment pre and post workout was performed, which consisted of 30 min warm up and 120 min of specific training. Scapular dyskinesia was evaluated as 'yes or 'no' as for the presence or absence of abnormalities in the scapular-thoracic movement, respectively. Results: As a result of this study we identified a prevalence of scapular dyskinesis in nine athletes from twelve in the pre-training (75%) and after the training session only one athlete evolved with standard dyskinesia, resulting in the cumulative prevalence of 10 athletes (83%) in this population. Conclusion: This study concluded that a single training session was able to increase the prevalence of scapular dyskinesia in 8% (or one athlete) of volleyball players.
