College of Physical Education,Yibin University,Yibin 644,China) Abstract:In order to find the snatch features of the excellent athlete,using the three dimensional kinematic approach to par ticipate in 213 National Games weightlifting competition athletes 125kg snatch Long Qingquan technology research. The re sults showed that:at the beginning of the first exhibition of the hip extensor mastered the correct technique to mention the bell; reduce knee consuming stage. 8s,Knee flexion 3Deg back only to 18. 4Deg,reduce knee with traditional techniques are quite different;force stage hip and knee angle changes consistent and reaches its maximum at the same time,reflects the supe rior force coordination.
