摘　　要：通过运用MEGAWIN 12导肌电测试仪,对现阶段我国3名优秀女子铁饼运动员的整个投掷技术过程中左右对称的8块肌肉进行了生物电测试,结果发现,孙太凤下肢肌肉力量好,腰腹肌力量差;宋爱民整个肌肉力量小,特别是腰腹肌力量,但肌肉积分速率较快,肌肉之间的协同用力程度高;李艳凤肌肉力量大,放电速率慢,各块肌肉之间的协同用力程度差。By using MEGAWIN 12 myoelectricity tester,the authors did a bioelectricity test on 8 left-right symmetrical muscles in the entire technical process throwing by 3 excellent female discus throwers in China today,and re-vealed the following findings： SUN Tia-feng had good lower limb muscle strength,but poor lumbar and abdominal muscle strength;SONG Ai-min had weak overall muscle strength,especially lumbar and abdominal muscle strength,but a faster muscle integration rate,and a high degree of coordinated power exertion between muscles;LI Yan-feng had powerful muscle strength,but a low discharge rate,and a poor degree of coordinated power exertion between various muscles.
