ISOKINETIC ANALYSIS OF MEDIAL AND LATERAL ROTATORS RATIO OF GLENOHUMERAL JOINT IN MALE BRAZILIAN VOLLEYBALL TEAM
Keywords:shoulder, athletes, isokinetic
AbstractThe purpose of this study was to analyze the ratio of medial and lateral rotators of glenohumeral joint in the male Brazilian Volleyball Team under 19 and 21 years-old. Twenty athletes under-19 and fifteen athletes under- 21, participated in this study. The Dynamometer Isokinetic Biodex 3 System Pro® was used to assess antagonist/agonist (RL/RM) ratio at 60º/s and 360º/s. A significant difference was found in ratio (RL/RM) between the categories, on the dominant limb (F= 11,840; p=0,0016 at 60º/s and F= 7,00; p= 0,0124 at 360º/s) and on the non-dominant (F= 20,269; p= 0.0001 at 60º/s and F= 11,223; p= 0,0020 at 360º/s). The under-21 athletes of Brazilian Volleyball Team presented RL/RM ratios below the expected values described in the literature.
