Karate is a sport widely practiced around the world, with its number of practitioners constantly growing. His techniques involve complex movements of upper and lower limbs and require the performer speed, agility, technique, precision and efficient decision making. Due to expansion in the number of practitioners and competitions with demanding technical level increasing, its practitioners as well as their trainers and technicians have expressed the need for scientific support accordingly. Therefore, the aim of this study is to determine what biomechanical indicators differentiate the performance of athletes of different competitive levels in Karate while performing the Gyaku Tsuki and Mae Geri strokes. To this end, the following specific objectives were established: (1) analyze dynamometric parameters during flexion and extension isometric and isokinetic of the shoulder, elbow, knee and hip joints of athletes from different competitive levels in karate; (2) analyze temporal parameters of the execution of Gyaku Tsuki and Mae Geri strokes in athletes of different competitive levels in karate; (3) analyze dynamic parameters in the execution of Gyaku Tsuki and Mae Geri strokes in athletes of different levels of experience in karate; (4) analyze coordinative parameters of the execution of Gyaku Tsuki and Mae Geri strokes and your variability in athletes of different levels of experience in karate; (5) analyze the relationship of electromyographic parameters of muscles involved in implementing of Gyaku Tsuki and Mae Geri strokes in athletes of different competitive levels in karate. For each proposed objective is presented a paper, in which were evaluated 14 male volunteers, aged 18 to 35, competitive practitioners of Karate, Black Belts, divided into two subgroups: Elite Group (GE), 07 individuals, competitors at national or international level; and Sub-elite Group (GSE), 07 individuals, competitors at regional or state level.
