Study On The Tactical Characteristics Of Chinese Men’s Curling Team Based On The Tactical System Of "Throw,End And Match"

Objective:Curling is the best team sport in China in the Winter Olympic Games.The Chinese men’ s curling team has made a series of breakthroughs from scratch in more than 20 years,but it is a pity that it has not been able to stand on the podium in the Winter Olympic Games.This study focuses on the bottleneck in the development of the Chinese men’s team--the tactical characteristics.Make full use of existing in the process of research achievements of theory and,the characteristics of China’s men’s curling tactics to conduct a comprehensive and systematic carding analysis,to study the curling tactical system,the innovation of China’s men’s curling tactics characteristics of quantitative research,and combined with the specific issues for further verification in China men’s curling of actual,eventually concise tactical characteristics of the Chinese men’s team,so as to enrich and perfect the theoretical system and curling for specific tactical training,selecting and implementing tactic to provide the reference.Methods:Through the observation,case analysis and other methods of literature,events curling tactical classification evaluation system for the research and—"throw,end,match" curling tactical system,and then on the basis of the research and curling tactical system,from the "throw,end,match" three both independent and mutually close contact level selected key indicators for quantitative research,on the basis of quantitative study qualitative conclusions.Study adopts the method of mathematical statistics,An analysis of the characteristics of stone tactics based on China’s men’s team in the implementation stage of 5-rocks free zone rules in 2012-2018 to 67 men’s curling championship game data for our country with the world of the high level team,the shooting percentages(PCT)and shooting percentages(PCT)with different points(DP)into the differences and correlation analysis;An analysis of the characteristics of end tactics based on China’s men’s team in the implementation stage of 5-rocks free zone rules of the 2012-2018 to participate in the 475 world games data with or without hammer.the efficiency evaluation of specific bureau for the cause of efficiency with hammer include:Hammer efficiency(HE),Steal defense(SD),Hammer factor(HF),the efficiency evaluation of specific bureau for the cause of efficiency without hammer include:Force Efficiency(FE),Steal Efficiency(SE;An analysis of the characteristics of match tactics based on China boasts four season 2014/2015-2017/2018 Olympics curling,qualifying for the World Cup men’s curling,winter Olympic Games men’s curling,curling continental cup,the world round-robin curling and grand slam and so on many of the world’s top curling tournament in 200 games of data based on with or without hammer,ends remain and different point,match the gap trend forecasting index-order of merit(Win Expectancy)statistical analysis,and with or without hammer and different point to order of merit(Win Expectancy)regression analysis,draw relevant formulas and weight factors.Finally,the classic matches of Chinese men’s curling team are selected for case study to verify the tactical characteristics of Chinese men’s curling team which are obtained from literature review and mathematical statistics.Results:The "throw,end,match" curling tactical system is based on the theories of military tactics and sports training.The "throw,end,match" curling tactical system created by this research basically covers the current domestic and foreign most advanced tactical classification and research indicators,the related content of the tactical system and the existing curling tactical theoretical research,competition practice and digital services have a high degree of integration,and is suitable for the specific situation of Chinese men’s team.Through the analysis of relevant indicators,it can be concluded that:The shooting percentages(PCT)is an important tactical index of basic curling tactics.Throw,although is curling technology,throw,shooting percentages(PCT)tend to reflect the position of the curling of expectations and the actual more tactical significance,therefore,throw,shooting percentages(PCT)can better evaluate team at a single or a stage event in the overall performance,China and the world of the high level curling in throw,the shooting percentages(PCT)has a slight difference,but the gap tends to reflect on and the top team in the process of competition,and this gap in the process of and most teams in are often not statistically significant,In addition,the correlation between the PCT difference of Chinese men’s team and the opponent’s team and the difference points is higher than that of world men’s team.In the case of the end without hammer,the Force Efficiency(FE)and the Steal Efficiency(SE)of the Chinese men’s team are close to the world top level,and the defense ability is strong without hammer.However,in the case with hammer,hammer efficiency(HE)is significantly insufficient,the Steal defense(SD)is close to the world top level,and the Hammer factor(HF)is not high.The Oder of merit(Win Expectancy)of Chinese men’s team in the World Match is the same as that of the world men’s team,but there are slight differences in individual competitions.The contribution rate(R2=0.728)of the Chinese men’s team to the Oder of merit(Win Expectancy)is nearly 75%(R2=0.728),which is very different from the world’s top level men’s team.The tactical characteristics of the Chinese men’s curling team are obtained from the throw,the end and the match.The results confirm and support each other.After the case verification of the relevant results in the key matches in the history of the Chinese men’s team,the relevant results are consistent with the reality of the Chinese men’s team competition.Conclusion:(1)Tactical ability is the key factor to improve the competitive ability of Chinese men’s team,The analysis of the tactical characteristics of Chinese men’s curling team is suitable for adopting the“throw,end,match”curling tactical system,and the quantitative analysis is the foundation of the study of curling tactics;(2)Based on the curling tactical of "throw",From the statistical analysis of the basic tactical index PCT,it can be seen that the tactical decision-making and implementation of Chinese men’s team are relatively stable with few changes,and the tactical characteristics remain relatively fixed for a long time.PCT can reach the average level of the world’s High-level Men’s team,but there is a significant gap with the top team PCT,so the tactical rationality needs to be further provided;(3)Based on the curling tactical of "end",According to the analysis of the game tactics based on the classification of attack and defense tactics,the main tactical characteristics of the Chinese men’s team in a single game are mainly defensive counter attack tactics.In the case of the first team,FE and SE are close to or even reach the level of the world’s top team,that is,they can effectively control the opponent in the case of the first team.On the contrary,in the case of backhand,he has significant deficiencies,and the offensive scoring(HE)ability is not strong,because it mainly adopts defensive tactics,making SD close to the world’s top level.The ability of backhand defense opponents to steal points is higher in the index evaluation,but the total backhand scoring rate HF is not high.In a single game,the team’s offensive ability is not strong,especially the offensive ability of backhand needs to be strengthened;(4)Based on the curling tactical of"match",In the different competition scenes of the whole game,the Chinese men’s team further showed the characteristics of defensive counter attack tactics and very resilient.The multi factor analysis of the winning expectation once again proved the Chinese men’s team’s safe and conservative playing style.(5)There are three tactical level results,the main tactical characteristics of the Chinese men’s team are:the team tactics remain stable for a long time,habitual use of conservative,defensive counter attack tactics,lack of offensive ability,strong defensive ability.(6)Based on the objective reasons,the following problems should be solved:the rationality of Chinese men’s curling throw(PTS),the tactical relationship between bases,It is gradually added in the further research.In addition,the introduction and application of world advanced curling tactics evaluation index should be long-term and necessary.
