Objective: The aim of this study was to analyze muscle strength levels in wheelchair rugby athletes. Methods: The sample was 10 athletes (men) with spinal cord injury at cervical level (tetraplegia) with mean age of 31.1 ± 5.06 years. The athletes were recruited in the rugby team in wheelchair of the Motor Activity and Adapted Sport Project of the University of Campinas (ADEACAMP/UNICAMP). Results: In order to analyze the isometric muscular strength levels (flexion/extension of the shoulders and elbows), dynamometer was used, while muscle thickness was verified by ultrasound (flexors and extensors of the elbow, both sides), using 7.3 MHz of the linear-array probe. Point bi-serial correlation was applied to verify associations of game position and strength; while Spearman’s correlation verified associations of strength and dominant and nondominant sides, and the relationship of agonist versus antagonist muscles. Moreover, the Mann Whitney U test was used to compare first to second-string players regarding strength and muscle thickness. Conclusion: We concluded that the higher the functional classification, higher the values of maximum isometric voluntary strength; and that the isometric strength correlates with their rugby performances.
