In recent years,competitive Taekwondo has continued to develop,Meantime Taekwondo athlete’s level in the world has been continuously improved.No matter how the Taekwondo competition develops and changes,"winning" is always the goal pursued by athletes and coaches.The research will focus on the relationship between the two factors(technical and tactical application,score changes)and the outcome of the competition in Taekwondo competitions.Explore its inner law.This article takes the quarter-finals of the four women’s competitions of the 2019 World Taekwondo Grand Prix Series and thereafter as the analysis object,using literature materials,expert interviews,video observation methods,mathematical statistics and logical analysis.The thesis provides the conditions and theoretical support for writing,analyzes the differences in the use of technical and tactical indicators between winning and losing games,and uses binary logistic regression analysis to filter out the significant impact on the regular wins and losses of Taekwondo competitions.The core technical and tactical indicators for creating a Logistic regression predictive model about winning and losing results.At the same time,this article will also study the changes in the score at each stage of the game,and link it with the relationship between wins and losses,analyze its internal correlation to find out the specific characteristics and differences of the advantages and disadvantages of the score,so as to better guide future training and competition.The main conclusions are as follows:1.The comparison of the application effect of basic technology shows that there is no difference in the order of technology selection between the winner and the loser,but there is significant difference between the side kick and the down split in the application effect;There are significant differences in the scoring effect between the forward horizontal kick and the side kick and the straight punch.The success rate of forward transverse kick,side kick,hook kick and straight punch has significant difference.Medium and high and single combo technology use effect comparison,are given priority to the middle,high auxiliary,one-click,combo auxiliary,technical scores and success rate has significant differences.There is no difference between the two sides in tactical choice and tactical scoring order,and there is significant difference between the winning side and the losing side in tactical success rate and scoring.2.The regression model of correlation between technical indexes and match victory and loss is Z=0.473X1+0.432X2+0.853X3-1.07X8+0.256X9-1.314.The overall key technical factors affecting the victory and loss of high-level women’s Taekwondo match are the foul times,the score of side kick and the score of front cross kick.The regression model of the correlation between the tactical index and the match victory and loss is Z=0.448x1+ 0.588x2+0.982x3-1.330.The overall key tactical factor affecting the victory and loss of the high-level women’s taekwondo match is the oncoming tactics.3.The "win-win-win" or "win-win-lose" structure dominated the relationship between the results of all Taekwondo matches.There is a weak correlation between winning and losing points,and a strong correlation between winning and losing points.The winning side leads the losing side in the number and length of consecutive points,especially in the third game.Summarize the game win/loss correlation strength ranking:first two games>,second game>,third game>,first game.
