新兴冬奥项目之混双冰壶技战术的关键影响因素研究

Research on the key Influencing Factors of theTechnique and Tactics for Mixed Double Curling as An Emerging Winter Olympic Sport

为了提高我国混双冰壶运动的综合能力,找出与世界混双冰壶强队的技战术差距,同时更好地备战2022年北京冬奥会,运用数理统计、文献资料、专家访问等研究方法对2015-2019年世界混双冰壶比赛中国队共计42场比赛的胜负总分total win and lose、首局后手次数times of LSFE(Last Stone First End)、偷分局stolen ends、每局最后一壶效果last stone Eff、关键壶效果PP Eff(power play efficiency)、得失大分局win or lose a game by big score(points scored greater than or equal to 4)等关键影响因素,以及参赛队员投壶技战术的大量数据进行搜集、统计并加以分析。主要结论:本方总胜分The total scores of the team、首局后手次数、偷分局、每局最后一壶效果、关键壶效果等变量相互间存在不同程度的正相关;本方总负分The total negative scores of the team与对方首局后手次数the opponent’s times of LSFE、对方偷分局之间存在正相关,与每局最后一壶效果存在负相关;对方偷分局与每局最后一壶效果、关键壶效果存在不同程度的负相关;从投壶技术类型the stone delivered techniques types的数据可以看出,女队员选用投准技术stone delivered accurate techniques较多,主要以控制局面为主,同时为男队员进攻战术的实施打好基础。建议:要想提高中国队在比赛中的总胜分,必须合理调控偷分局数、首局后手次数、每局最后一壶效果、关键壶效果这4个可控因素之间的关系;在合理解决好本方的偷分局数与首局后手次数辩证关系的基础上,有效改善每局最后一壶效果,为指导中国队参加2022年北京冬奥会混双冰壶赛提供理论基础和科学依据。

In order to improve the comprehensive ability of mixed doubles curling in China,find out the technical and tactical gap between China and the world’s strong mixed doubles curling teams,and better prepare for the 2022 Beijing winter Olympics,the article use the mathematical statistics、literature materials、expert interviews and other research methods,the paper fits the data of China’s 42 matches in the world mixed doubles curling competition from 2015 to 2019 by analyzing the key influencing factors which including total win and lose,times of LSFE(Last Stone First End),stolen ends,last stone Eff.(power play efficiency),win or lose a game by big score(points scored greater than or equal to 4),as well as the large amount of data of the mixed doubles player’s stone delivered techniques and tactics.The main conclusions shown that:The total scores of the team,times of LSFE,stolen ends,last stone Eff.of each game,last stone Eff.and other variables are positively correlated with each other to varying degrees;The total negative scores of the team not only has a positive correlation both with the opponent’s times of LSFE and stolen ends,but also has a negative correlation with last stone Eff;The opponent’s stolen ends has a negative correlation with last stone Eff and PP Eff;what’s more,it can be seen from the data of the stone delivered techniques types that female players are more likely to use stone delivered accurate techniques,mainly to control the situation and lay a good foundation for the implementation of male players’offensive tactics.Suggestions:In order to improve the total winning scores of the Chinese team during the match,the relationship among the four controllable factors including the times of stolen ends,the times of LSFE,the last stone Eff,and the PP Eff must be reasonably adjusted.On the basis of reasonably solving the dialectical relationship between the times of stolen ends of our team and the times of LSFE,to effectively improve the last stone Eff,which provides the theoretical basis and scientific basis for guiding the Chinese team to participate in the mixed doubles curling competition in 2022 Beijing winter Olympics.
