摘　　要：目的:寻找索契冬奥会单板U型场地滑雪男、女运动员决赛成绩与难度战术间的关联性及其发展趋势。方法:采用视频分析法、调查访谈法,文献资料调研法和对比分析法,对索契冬奥会单板U型场地滑雪决赛男、女运动员两轮比赛的技术动作进行对比分析,研究其比赛成绩与难度战术选择间的关联性,并与温哥华冬奥会男、女决赛难度战术进行比较。结果:成绩上升与下降的男、女运动员中均有加难及维持难度战术的选择,且女运动员成绩上升与下降者中均另有减难战术的选择。索契冬奥会女运动员中选择加难战术者较温哥华冬奥会明显减少(66.7%→33.3%),并有25%选择减难战术;而男运动员中的难度战术选择趋势与温哥华冬奥会相同。结论:索契冬奥会单板U型场地滑雪男、女运动员的决赛成绩与难度战术选择无关联性,与温哥华冬奥会相比,女子决赛难度战术选择有显著性变化趋势,男子难度战术则趋势相同。The purpose is to find out the association between the final results of male and female half-pipe athletes in Sochi Winter Olympic Games and the difficult tactics and the developing trends of the difficult tactics. Methods：With the methods of video analysis, expert interview, documental information and comparative analysis, this paper compared and analyzed two rou- tines of technical difficulty motions of male and female athletes in the half-pipe final in Sochi Winter Olympic Games, so as to find out the association between the final results and the diffi cult tactics, as well as comparing them with the ones in Vancouver Winter Olympic Games. Re sults： In male and female athletes with higher results and lower results, difficult tactics of im- provement and maintenance were selected. Besides, difficult tactics of reduction was also chosen by female athletes both with higher results and lower ones. Compared to the Vancouver Winter Olympic Games, the female athletes chosen the difficult tactic of improvement reduced signifi- cantly （66.7 %→33. 3%）, and 25 % athletes selected the difficult tactic of reduction, while the trend of difficult tactics chosen by male athletes was identical to the one in Vancouver Win ter Olympic Games. Conclusions ：There was no association between the final results of half- pipe athletes in Sochi Winter Olympics. The choice of difficult tactics in female final has signif- icant change trend, while the trend of difficult tactics in male was identical comparing to the Vancouver Winter Olympic Games.
