Correlation between Elite Male Weightlifters' Trunk and Knee Isokinetic Muscle Strength and Special Performance

Objective: The purpose of this paper is to investigate the characteristics of elite male weightlifters' trunk and knee isokinetic muscle strength, and analyze their correlation with snatch and clean and jerk performance. Method; IsoMed 2000 is used to conduct isokinetic muscle strength test onl2 subjects"trunk and knee joint. Results; The indexes of the relative peak torque, untagonist muscle, the ratio of the active muscles and the ratio of side muscle with the same name are analyzed. The correlation between the relative peak torque of the trunk and knee and the subjects' snatch/weight, lean and jerk weight/weight are also analyzed Conclusion; (1) The subjects F/E ranges from 0.27 to 0.50, H/Q(0.41-0.73), with the difference of most subjects' side muscle of knee with the same name being within 20%, but in the quick test, 3 players need to strengthen the weaken side muscle group. 2)Snatch/weight demonstrates moderate positive correlation significantly with back extensor and knee medium - speed flexor, knee jo
