| Abstract: | This study adopts isomed2000 system to get the biomechanical characteristics of excellent TKD athletes＇ knee muscle group. The corresponding knee joint flex muscle group Isokinetic eccentric contraction angle angle range of the peak torque coming is between the 152.81- 159.33° ,The corresponding knee joint exertion muscle group concentric eccentric contraction angle angle range of the peak torque coming is between the 113.01-108.61° ;the relative force moment grade peak coming when the knee joint flex and extent muscle group is 240°/s, the relative force moment grade peak of the right knee flex muscle group is 29.62 Nm/s.kg, the relative force moment grade peak of the right knee extent muscle group is 51.42 N.m/s.kg. |
