This study was done to propose an effective training method which improve the isokinetic muscular function around the knee and waist joint. 14 bodybuilders were classified into traditional method group(n=7) and HIT(High Intensity Training) method group(n=7) according to the movement repetition velocity during weight training. Hit method was slower than traditional method in the movement repetition velocity. Subjects of two groups were performed 12weeks training program. SPSS 15.0 for windows was used for data analysis. Paired t-test was conducted to compare the difference between pre and post training, and ANCOVA(analysis of covariance) was enforced to compare the effect of post training between traditional and HIT method group. In the result of 12weeks training, the maximal muscle strength and muscular endurance of knee joint were increased in both traditional method and HIT method. Maximal muscle strength of waist joint improved in both extensor and flexor in the HIT method, but only flexor in the traditional method, and muscular endurance of waist joint improved in the traditional method. In conclusion, HIT method was more effective training method to improve the muscle strength and muscular endurance of knee joint and muscle strength of waist joint.
