Aim. The aim of this study was to analyze the muscle performance of lower limbs in young elite Brazilian Badminton athletes, and to make comparisons between genders in the variables: peak torque (PT), maximum power (MP), fatigue index (IF) and H/Q of the muscles involved in the knee joint.
Methods. Participants included 13 athletes (male n= 8) and (female n=5), aged between 14 and 20 years, belonging to the junior and senior categories, on the National Brazilian Badminton Team. The concentric isokinetic muscle performance of the flexor and extensor muscles of the knee, in both limbs, was measured using an isokinetic dynamometer at an angular velocity of 60°∙s-1, 180°∙s-1 e 240°∙s-1, to assess PT, MP and IF respectively.
Results. The comparison of PT values (60º∙s-1), MP (180º∙s-1) and IF (240º∙s-1) showed no statistically significant differences between the limbs nor between genders. The comparison of the ratio H/Q between the three tested velocities showed a significant difference (p<0.05) between the H/Q to 60º∙s-1 and 180º∙s-1 and 60º∙s-1 to 240º∙s-1 in both genders.
Conclusion. This study found no significant differences in muscle performance of Badminton athletes when comparing genders and females were not more prone to injuries as suggested by the literature.
