The Influence Of Technical Performance On The Outcome Of The 14th National Games Men's Shuttlecock Team Competition (youth Group

With the continuous development of shuttlecock sports,higher requirements have been put forward for athletes’ technical and tactical levels."Winning the game" has always been the unremitting goal pursued by athletes and coaches.The technical level of shuttlecock is the most important winning factor in shuttlecock matches,and its application and performance have a significant impact on the outcome of the game.This study uses research methods such as literature review,video observation,and mathematical statistics to collect and analyze all game videos of the top eight teams in the men’s shuttlecock team match(youth group)of the 14 th National Games,objectively analyzing the advantages and disadvantages of the top eight teams in terms of technical performance;When analyzing the data of shuttlecock matches,the logistic regression analysis method is used to construct a judgment model for technical winning factors,in order to better understand the winning factors in shuttlecock matches and grasp the winning laws of shuttlecock sports.I hope to bring some inspiration to the development of shuttlecock in China and provide theoretical basis for winning and training in shuttlecock competitions.At the same time,the logistic regression model was first used in the analysis of shuttlecock technology,which is also one of the innovations of this study.The conclusions of this study are as follows:(1)In terms of the influencing factors of technical victory,based on the differences in the effectiveness of technical performance among the top eight teams in winning and losing matches,the logistic regression analysis method is used to construct a judgment model for technical victory factors;The established model is Logit(P)=9.213+0.527 * serve break rate-0.331 * serve miss rate+0.296 * spike score rate+0.129 * defense hit rate-0.210 * block miss rate-0.076 * pass error rate;After testing,the model has a high degree of fit and can predict the technical winning factors in shuttlecock matches,with strong practicality and accuracy.Among the key factors that affect the victory or defeat of the top eight teams in a game,the service breaking rate,spike scoring rate,and defense in place rate have a positive impact on the victory or defeat of a single game;The rate of missed serve,missed block,and missed pass have a negative impact on the outcome of a single game.(2)Among the influencing factors of technical victory,for every 1% increase in the serve break rate,the probability of each team winning in each game will increase by1.693 times;For every 1% increase in the rate of missed serve,the probability of each team winning in each game is reduced by 0.718 times;For every 1% increase in spike scoring rate,the probability of each team winning in each game will increase by 1.345times;For every 1% increase in the rate of defense in place,the probability of each team winning in each game will increase by 1.138 times;For every 1% increase in the block miss rate,the probability of each team winning each game will decrease by0.811 times.If the pass error rate does not increase by 1%,the probability of each team winning each game will decrease by 0.927 times.(3)There are significant differences in the technical performance of the top eight teams who have entered the knockout stage of this National Games in terms of receiving and serving well,making mistakes in receiving and serving,making effective passes,making mistakes in passing,making average spikes,being blocked,making mistakes in spiking,and making mistakes in blocking.(4)In the service technique aspect,what affects the victory or defeat of each game is the breaking attack rate of the high back forward service,which has an impact on the victory or defeat of each game...
