In our country, weightlifting is the superior event. In the Olympic games in 2004,Chinese weightlifters have gained 5 gold medals from all the 15 gold medals. Snatch is the first event in weight lifting match, so its success or failure will affect all the weight lifting match. Scientific researchers have done many researches in snatch and have made many achievements. Most of their achievements result in finding weightlifters` movement characteristics from analyzing weightlifters` gravity movement,movement characteristics of weightlifters` every party,muscle strength characteristics and the barbell` track. Furthermore, they have researched different weightlifting movements` effects to weightlifters` achievement and the similarities and differences of interior and overseas` outstanding weightlifters` movement characteristics. But few of the researches focus on reserve weightlifters` movements. Especially they did not research how to correct their movements to be outstanding weightlifters.In this aspect, most of the coaches will solve it by their experiences, but the experts advise the coaches scientific analyze weightlifters` movements. In this paper, we analyzed weightlifters` snatch movements. We analyzed their movement characteristics by barbell and weightlifters` sports data. The main conclusion as follows: barbells` movement in left and right direction is excessive; in the snatch course, the time distribution of every party is not reasonable, and this destroy the snatch rhythm in some degree; weightlifters need to find the reasonable angles of main body parties in snatch; weightlifters` strength is not bad but they need to develop their strength in both sides in order to avoid bringing about weak side.
