Introduction: The aim of this study was to compare isokinetic variables of the knee such as peak torque and relative balance of agonist/antagonist of knee flexors and extensors between athletes of kickboxing (KB) and taekwondo (TKD). Materials and Methods: Ten male athletes from martial arts were included in this study (18±3 years old, 1.75±9cm and 65±10kg): five TKD athletes and five KB athletes. The assessment of peak torque and relative muscle balance was performed using the Biodex Multi-joint System 3 dynamometer. Data analysis was performed by means of non-parametric statistics (Mann-Whitney test) with statistical significance at p<0.05. Results: This study showed no differences in peak torque and relative balance of agonist/antagonist of the sports examined. Furthermore, it was found in all assessed athletes a difference of less than 10% when compared the peak torque between the right and the left lowers limbs and a difference of less than 50 to 80% in the ipsilateral quadriceps, harmstrings ratio. Discussion: This information suggests that athletes of TKD and KB have similar conditions of strength and low risk of musculoskeletal injury associated with the knee joint. [PUBLICATION ABSTRACT]
