- Abstract
Introduction. Racquet sports are characterized by repeated movements above the level of the head, implying that the dominant shoulder must develop strategies that allow it to acquire suffcient laxity to ensure the necessary articular ranges and stability to avoid possible articular dislocations, predisposing the area to possible shoulder postural alterations. Objective. To examine if there is asymmetry in the scapular position between the dominant and non-dominant shoulders in non-professional racquet players. Methods. Cross-sectional, descriptive, and analytical study in 83 tennis and/or paddle tennis players. Scapulothoracic angle, normalized lateral scapular displacement, scapular height index and distance from the acromion to a reference vertical were evaluated through photographs, later processed and analyzed with SAPo software. Descriptive statistics and repeated measures linear regression models were used for data analysis, adjusting the models for sex, age, BMI, and profession. The effect size was calculated using the partial eta-squared (h2), with values p>0.14 being considered large. Values of p<0.05 were established as statistical significance. Results. On the dominant side, the players presented smaller scapulothoracic angle [MD: -2.0; P=0.011]; smaller normalized lateral scapular displacement [MD: -0.08; P=0.007]; greater scapular height index [MD:0.48; P=0.000]; and greater distance from the acromion to a reference vertical [MD:1.29; P=0.007]. However, only the scapular height index and the distance of the acromion to a reference vertical were considered high (h2>0.30). When subjects were analyzed by sport subgroup, tennis players presented fewer asymmetries as compared to the paddle or mixed group. Conclusions. Non-professional racquetball players presented asymmetries in scapular position between the domi- nant and non-dominant shoulders, differing in frequency and magnitude according to the type of sport practiced.
