运用三维运动学的研究方法，对我国9名举重国际健将比赛条件下抓举同等杠铃重量时成功与失败的18次试举技术进行对比研究，探讨优秀运动员特定负荷下成功试举与失败试举技术特点及差异。研究结果表明，从动作的时空特征来看成功试举与失败试举间不具有显著性差异，成功试举与失败试举伸膝提铃阶段合加速度矢量方向具有显著性差异，成功试举时提铃用力较均匀，而失败试举时运动员对杠铃不稳定作用力的方向是造成试举失败的主要原因。

Using the methods of 3D motion analysis,this paper made a comparative analysis of the 9 elite Chinese male weightlifters' 18 trials. Their successful and unsuccessful snatch lifts with the same load under competitive conditions were recorded so as to seek the characteristics and differences between the successful and unsuccessful lifts of the specific loads.The result shows that there is no significant difference between the successful and unsuccessful lifts based on the temporal and spatial characteristics of the snatch movements. However, significant difference was found in the vector of the resultant linear acceleration of the barbell in the first pull of the successful and unsuccessful lifts. It seems that a proper direction of force application to the barbell leads to successful lift and the direction of unstable force application to the barbell is the main reason for unsuccessful lift.
