Abstract :The relationship between inter-limb strength asymmetry and athletic performance is not clearly well-known. Different results in the literature makes it difficult to form a common consensus on this issue. The aim of this study was to investigate the relationship between inter-lower limb strength asymmetry insert ignore into journalissuearticles values(ILLSA); values and jump and sprint performances. Forty-eight individuals insert ignore into journalissuearticles values(21.5±2.8 years, 1.74±0.1 m, 67.3±9.7 kg); voluntarily participated in this study. All participants participated in squat insert ignore into journalissuearticles values(SJ);, countermovement jump insert ignore into journalissuearticles values(CMJ);, 40m sprint run tests and right and left isokinetic concentric knee flexion and extension strength insert ignore into journalissuearticles values(IS); test at low insert ignore into journalissuearticles values(60°.s -1 ); and high insert ignore into journalissuearticles values(300°.s -1 ); angular velocities. The symmetry angle formula was used in order to determine the isokinetic knee strength asymmetry values between inter-lower limb. According to the results it was revealed that there was no relation insert ignore into journalissuearticles values(p>0.05); between ILSSA at low and high angular velocities and squat jump insert ignore into journalissuearticles values(r = -0.106 ̶ 0.200);, countermovement jump insert ignore into journalissuearticles values(r = -0.11 ̶ 0.087); and 40m sprint insert ignore into journalissuearticles values(r = 0.012 ̶ 0.810); performance. In conclusion, there is no negative or positive relationship between inter limb isokinetic knee strength symmetry angle and jump and sprint performances in physically active individuals.
