Shoulder range of motion and strength in young competitive tennis players with and without history of shoulder problems
Objective: To assess the effect of a history of shoulder problems on the shoulder flexibility and strength in young competitive tennis players.
Design: Cross-sectional study.
Participants: Ninety-one competitive and asymptomatic tennis players aged between 8 and 15 years old were divided into two groups according to the presence or absence of a history of shoulder problems.
Outcome Measures: Glenohumeral joint ranges of motion and the strength of eight shoulder muscles were bilaterally assessed. Five agonist/antagonist muscle strength ratios were also reported. Ranges of motion, strengths and strength ratios were bilaterally compared between the two groups.
Results: Players with a history of shoulder problems presented a higher total arc of rotation for both glenohumeral joints (p=0.02) and a lower external/internal glenohumeral rotator muscle strength ratio (p=0.02) for both sides. They also presented stronger upper trapezius (p=0.03) and dominant serratus anterior (p=0.008) muscles than players without a history of shoulder problems.
Conclusion: Having a history of shoulder problems may alter the balance between mobility and stability within the shoulder complex suggesting that particular attention should be given to dominant and non-dominant shoulder functions by coaches and clinicians.
