The Evaluation Model And Empirical Analysis Of The Ability Of Attack And Defense Performance Of Women Volleyball Team’s Opposite

In recent years,the Chinese women’s volleyball team has achieved better results by building an offensive system with Ting ZHU as its core.According to statistics from the World Volleyball Association,the "extreme value" development of competitive volleyball is reducing the gap in competitive strength between the strong teams in various countries in the world.The second pass of European and American teams has become the core tactical system of the team’s offense,which has led to the Chinese women’s volleyball team.The advantages of the offensive system are gradually weakening.To maintain the advantages of the fast and changeable tactical system of the Chinese women’s volleyball team,it is necessary to enhance the competitive strength of the Chinese women’s volleyball team.Then,it is an effective way to improve China’s offensive and defensive capabilities in response to the second pass and combine the offensive and defensive capabilities of Zhu Ting with the two offensive defensive systems.This article takes the role and role of the second pass as the research orientation,conducts preliminary research and empirical evaluation of individual cases by constructing an offensive and defensive performance evaluation model,and discusses the positioning of the second pass,technical and tactical play.Based on this,the introduction and the first chapter mainly describe the research background and significance,research methods and paths,etc.Through the collation and extraction of the literature,define the concepts of coherent second pass,offensive and defensive capabilities,and sort out the roles and responsibilities of coherent second pass.At the same time,the framework and method of constructing the performance evaluation model of the second-pass offensive and defensive capabilities are discussed.In chapter two,guided by the system coordination theory,the performance evaluation of the second-pass offensive and defensive capabilities is transformed into a multi-level single-target system problem.Through Delphi method,video analysis method,etc.,construct the performance index system of the second-pass offensive and defensive ability,and design the statistical table and single-factor index scoring standard of the second-pass offensive and defensive ability performance;Chapter III,the evaluation index system based on the previous research,Using analytic hierarchy process,questionnaire survey and other methods to improve the performance of the second-pass offensive and defensive capability performance hierarchical model.Based on the fuzzy comprehensive evaluation method,a fuzzy comprehensive evaluation model of the offensive and defensive capabilities of the second pass is constructed,and a systematic and objective evaluation of the performance of the offensive and defensive capabilities of the second pass is carried out.In chapter four,the applicability of the evaluation model is verified through empirical analysis and the current situation is understood.The world women’s volleyball team responds to the trend of the ability distribution.Take the second pass of the World Cup Finals of the 219 Women’s Volleyball Team as an example.In Chapter 5,by summarizing the results of the above research,it puts forward some reference suggestions,summarizes the deficiencies of the research,and puts forward the outlook.Main findings:(1)Research and build an evaluation system for the performance index of the second set of offensive and defensive capabilities,including two aspects of the criterion layer,10 evaluation dimensions of the factor layer,and 44 items of the evaluation layer,which enriched the theoretical content of the second set of relay to a certain extent.Based on the evaluation index system of the offensive and defensive capabilities of the second pass and related technical and tactical statistical tables,a performance statistics table of the offensive and defensive capabilities of the second pass was designed.The sample data of the offensive and defensive capabilities of the second pass was obtained through video analysis.Evaluation criteria for factor indicators.(2)The fuzzy comprehensive evaluation model constructed and researched is used to systematically and objectively evaluate the performance of offensive and defensive capabilities of the second pass from the bottom to the top,forming a dynamic evaluation result and giving a certain value.(3)In the standard layer,the weight of offensive capability performance reaches 64.58%,which indicates that the evaluation of the performance of the offensive and defensive capabilities of the second pass is more focused on the performance of the offensive capability.;The weight of the three factors in the factor layer: the 2nd-point smash,the back-row smash,and the block are 32.49%,19.9%,and 17.84%,which are the most important indicators for evaluating the offensive and defensive performance in the second set.The weight of the three is more than 70.%,Indicating that the main duties of the second pass on the court are to smash the ball at the 2nd position,attack in the back row,and block.(4)Taking the 2019 Women ’s Volleyball World Cup Final Four as the example of an empirical analysis,it is of certain reference value to comprehensively analyze and determine the current positioning of the world women ’s volleyball team ’s second set of second volleyball skills,tactics,play,and offense and defense capabilities.Main research recommendations:(1)Based on the index weight of offensive and defensive ability performance system structure and the distribution of setter "offensive and defensive ability appraisal model of performance evaluation results,combining with the characteristics of Chinese women’s volleyball team basic conditions and advantages,to adapt to the actual situation in our country’s training plan and training objectives,to meet who became an important point of the offense of three-dimensional.(2)The strong teams in the competition gradually adjust by free pass,the coaches can conform to the development trend of world volleyball world,adjust the setter "tactics training focus,should be appropriate to reduce onto the defensive area,make its have more energy on the offensive,to strengthen the right side of attack and the core member of attack at spiking technique comprehensive department job setter" position,so as to improve the whole team offensive force.
