Research On The Technical And Tactical Structure Model Of The Collective Competitive Ability Of Chinese And Foreign Women's Volleyball Team

Background:Competitive ability is crucial in competitive sports,and it consists of different sub-competencies.The study of the technical and tactical structure of competitive ability in volleyball is conducted to construct a model of the technical and tactical structure of the collective competitive ability of Chinese and foreign women’s volleyball teams,through which the model reflects the common characteristics of the technical and tactical structure of Chinese and foreign women’s volleyball teams.Objective of the study:Compare the data on the effectiveness of the technical and tactical use of Chinese and foreign women’s volleyball,and analyse the differences in the effectiveness of the technical and tactical movement of Chinese and foreign women’s volleyball.By processing and analysing the match data,a model of the technical and tactical structure of the collective athletic ability of Chinese and foreign women’s volleyball teams is constructed.Research object and method:This paper takes the technical and tactical structure of the collective athletic ability of Chinese and foreign women’s volleyball as the research object.Using literature,expert interviews,questionnaires,video observation and mathematical statistics,the technical and tactical indicators of Chinese and foreign women’s volleyball teams were determined and analysed.A comparative analysis of the effectiveness of the use of Chinese and foreign women’s volleyball techniques and tactics was carried out,and finally a model of the technical and tactical structure of the collective competitive ability of Chinese and foreign women’s volleyball was constructed by processing and applying the data.Research results:（1）Independent sample t-test was conducted on the effect of all technical and tactical indicators,and excluding the effect of technical and tactical indicators without significant difference,we learned that the Chinese team was higher than the foreign team in the effect of receiving and serving errors,receiving and blocking errors,receiving and passing,and matting in place,and there was a significant difference with the foreign team.The Chinese team’s errors in receiving and blocking are much higher than those of foreign teams;（2）By determining the technical and tactical indicators,watching the video to count the technical and tactical indicators,and conducting independent sample t-tests on all the technical and tactical indicators counted,64 significant indicators were screened out.The significant indicators were used as the independent variables and the match win/loss as the dependent variables,and the significant indicators were screened again through binary logistic regression analysis,and the 6 most significant indicators were selected as single blocking errors,total number of double blocking under heart follow up,double blocking under heart follow up in place,fast attack success,strong attack errors and strong attack error rate.Finally,these six most significant indicators were used as discriminatory factors to establish a model for discriminating the technical and tactical structure of Chinese and foreign women’s volleyball team’s collective competitive ability;（3）the coefficients and constants of its discriminant function K were obtained through calculation,and the final Fisher discriminant function K formula was as follows:K_minus=1.213 single blocking errors+0.398 total number of double blocking down heart follow up+0.209 double blocking down heart follow up in place+0.937 fast attack success+0.069 strong attack errors+32.088 strong attack error rate-7.128K_win=0.812 single blocking errors+0.28 total number of double blocking down heart follow up+0.146 double blocking down heart follow up in place+1.214 fast attack successes+0.31 strong attack errors+21.527 strong attack error rate-5.893;（4）select the technical and tactical indicators between the two teams that won the first place,the United States,and the ninth place,China,for each set The final discriminant function K between the two countries showed that the US team had the highest win rate in the first set and the highest loss rate in the fourth set,which shows that the US team is a fast and hot team.China’s win rate was relatively high in the third and fourth games,which shows that the Chinese team is relatively slow.However,China’s overall loss rate was higher than that of the USA.The Chinese team should improve their ability to adapt to the game,try to shorten the adaptation time in the game,get into the game as soon as possible,and try to increase their chances of winning the first three games of the match.Conclusions:（1）Fisher’s discriminant model analysis method was used to construct a technical and tactical structure model of the collective competitive ability of Chinese and foreign women’s volleyball teams.（2）The technical and tactical structure model of the collective competitive ability of Chinese and foreign women’s volleyball teams was applied to the data.
