This study is aimed at furnishing information which will be able to help improve lower limb`s strength and plan training as given measures of knee joint`s rotation per angular velocity in the existing way of strength training, making use of□□Cybex NORM□□ tested for isokinetic strength to 10 persons Taekwondo athletes and trainees respectively among high school students, furthermore it will be informative to estimate the cause of injury occurrence in the muscule skeletal system in terms of a strength imbalance. Therefore, both concentric contraction and eccentric contraction were carried out among isokinetic strength tests - 5 times at 60°/sec, 5 times at 180°/sec, and 5 times at 240°/sec in each angular velocity of left and right knee joint, and then the results of those were as follows. Peak torque displayed the significant difference between 60°/sec and 180°/sec of the right and left flexor during concentric contraction, however during eccentric contraction it did at angular velocity 60°/sec of left flexor. In conclusion, according to the results of isokinetic knee joint strength testing between a group of athletes and a group of trainees in Taekwondo, it is estimated the former has more powerful lower limb`s strength than the latter in several items, and also it has been shown that Taekwondo athletes are able to kick more times than the other due largely to the athletes` fast neuromuscular reaction led by lower knee joint angle of peak torque than other items in a group of athletes. With regard to peak torque of flexor and extensor ratio, those results reach the level about 60%, however, it is absolutely necessary not only to develop lower limbs strength in balance through weight training and specific training prescription, also to prevent injury occurrence and to last as a player for a long time.
