摘　　要：针对2011年男子冰壶世界锦标赛参赛运动员的投壶技术进行投壶成功率(PCT)和投壶合理性(PTS)分析,划分投壶技术难度等级,采用逐步回归法确定各垒次PTS、PCT与运动成绩间的关系。结果表明,全队PCT和PTS应综合投壶效果的稳定性进行分析。在确定投壶技术3个难度等级的基础上,可使用各垒次PCT和PTS进行评价。回归方程提示,三垒PCT、四垒PCT和一垒PTS、四垒PTS对成绩的影响较为重要,可能为该项比赛的制胜因素。建议中国队应了解冰壶投壶技术评价的发展趋势,针对制胜因素进行训练,结合国内、外评分方法,建立更为完整的、国际先进的冰壶投壶技术评价体系。This paper introduced PCT and PTS score to analyzed male curlers in 2011 World Curling Championship, divided difficult level of shot, adopted stepwise regression to ascertain relationship among the PCT, PTS, and performance. The results show that the PCT and PTS of team should he analyzed with stability of shot. On the basis of three difficult levels, we can evaluate the shot with PCT and PTS of single curler. The regression shows that the PCT of third and skip, the PTS of leader and skip should be important effect on result, may be the winning factors in shot. It is proposed that Chinese team should understand the development trend of shot and train with winning factors. It recommended to combine the national method with international method, established a more complete, the international advanced curling shot assessment system.
