Abstract: The paper experimentally researches the influence of the two kinds of strength training (jumping and weight training) on muscle strength characteristics. 22 male sports students are divided into two groups and are respectively given two different kinds of strength training for their lower limb strength. Ergograph and isokinetic muscle testing system are used to collect the dynamic data of lower limbs and the joints muscle torque data before and after the experiment. The results show that the two kinds of strength training methods can improve muscle strength but differ in strength characteristics. Jumping training mainly works in improving muscle energy storage capacity and rapid muscle strength, while weight training mainly improves the concentric contraction ability and the absolute power of muscle
