Research On The Evaluation Of Offensive And Defensive Ability Of China Men’s Volleyball Side Attackers Based On "Full Data Model" Technical Statistics

With the rapid development and continuous innovation of modern competitive volleyball intelligence information,whether we can fully grasp and use the data for analysis,to a large extent,determines the competitive level of a sports event.In this paper,the evaluation model of attack and defense ability of men’s volleyball attackers is established by using the methods of literature,questionnaire and so on.Based on the "full data model",this paper makes statistics and collation on the data of the matches of each team in the 2022 Men’s Volleyball World League,and then on this basis,discusses and evaluates the current situation of the attack and defense ability of the side attackers in different teams,grasps the attack and defense strength of the side attackers of each team as a whole,analyzes the gap and advantages between the Chinese men’s volleyball team and each team,and finds out the factors causing the gap.It not only provides valuable suggestions for Chinese men’s volleyball team to break the downturn and step into the list of strong teams in the world,but also provides a strong basis for Chinese men’s volleyball team to understand and fully understand the current competition in men’s volleyball arena,in addition,it also lays a certain theoretical foundation for our men’s volleyball team to accurately grasp the strength and advantages of each team.The research results of this paper include the following aspects:(1)the evaluation system of frontier attackers’ attack and defense is constructed by using full data theory and Critic weight method.The results are as follows: main attack ability score = serve Vote value * 11.89% + spike Vote value * 25.70% + drop Vote value * 19.56% + first attack Vote value * 21.75% + Anti-counterattack Vote value *21.10%.Score of main attack and defense ability = Vote value of receiving service *33.37% + voice value of anti-spike * 14.89% + blocking Vote value * 51.74%;comprehensive ability of main attack and defense = offensive ability score * 61.39% +defense ability score * 38.61%.Score of offensive ability of second pass = Vote value of serve * 12.01% + Vote value of spike * 23.74% + Vote value of drop * 20.06% +Vote value of first attack * 21.56% + anti-counterattack Vote value * 22.63%;score of defensive ability of second pass = Vote value of anti-spike * 36.21% + blocking Vote value * 63.79%;comprehensive ability of attack and defense of second pass = offensive ability score * 63.84% + defensive ability score * 36.16%.(2)in terms of offensive ability,the offensive ability of the main attacker of the Chinese men’s volleyball team is 234.18,France is 277.72,the United States is 277.58,Poland is 274.00,Italy is 264.62;the offensive ability of the Chinese team to take the second pass is 245.18,France is 277.72,the United States is 277.58,Poland is 274.00,Italy is 264.62.(3)in terms of defensive ability,the defensive ability scores of the main attackers of the Chinese men’s volleyball team are 157.62,192.96 for France,187.45 for the United States,197.25 for Poland and 184.05 for Italy;the defensive ability of the Chinese team for the second pass is 152.00,179.39 for France,197.29 for the United States,168.00 for Poland and 171.37 for Italy.(4)in terms of comprehensive offensive and defensive ability,the comprehensive offensive and defensive ability of the main attacker of the Chinese men’s volleyball team is 218.64,France is 245.52,the United States is 243.36,Poland is 247.98,Italy is237.28;the comprehensive offensive and defensive ability of the Chinese team to receive the second pass is 232.94,France is 260.12,the United States is 264.61,Poland is 257.92,Italy is 252.22.
