Research On The Application Of Techniques And Tactics And The Factors Influencing The Winning And Losing Of The Chinese Women's Volleyball Major Competition In 2015-2018

In recent years,the Chinese women's volleyball team has re-emerged under the leadership of Lang Ping's head coach.While complying with the development characteristics of women's volleyball "high and male",they continue to learn advanced foreign tactics and improve their technical and tactical systems.The traditional strong team has caused a huge impact.Although the Chinese women's volleyball team has achieved record in the international competition of 2015-2018,it can still be seen that it does not have absolute winning strength when facing the strong teams in Europe and America.There are also some weaknesses and loopholes in the technical and tactical play.This paper uses video statistics,mathematical statistics and other research methods to compare and analyze the use of technical and tactical indicators between winning and losing games in 32 major international competitions of Chinese women's volleyball teams between 2014 and 2018,and use Logistic regression.The analysis and selection of the core indicators that have a significant impact on the winning and negative results of the game,in order to establish a Logistic regression prediction model of the winning and negative results,the main conclusions are as follows:1.In the active scoring technique,in terms of smashing,the effect of winning the smashing technique is better than that of the negative game.Zhu Ting and the deputy smashing ball have a better effect;the "main attack" and the second pass smashing score are lower;the blocking aspect,the winning net The technical application effect is better than the negative game.The double block is the most frequently used in the game.The number of people is an important condition for determining the effectiveness of the block.The more participants,the better the block effect.On the serve,the winning serve is better than the negative game.The second pass service is better,but the second pass wins,the negative effective serve rate is different,the serve effect is unstable,the secondary attack and the second pass serve poorly.2.In the offensive protection technology,in terms of receiving the serve,the winning serve is better than the negative game.The overall number of serve is more than the negative.The main attack and the free agent receive more serve times.The main attack and serve is not ideal.On the defensive side,the defensive effect.Better than the negative game,the offensive defensive effect is poor,the main attack and the free man win,the negative defensive effect is greater.3.In the receiving and attacking system,the receiving frequency of the left and right waist regions of the receiving ball link is the highest,the heart area wins,and the negative ball receiving wave fluctuates greatly.The front corner,the left waist and the left and right sides of the back area are connected.The weak link area of the serve;the attack on the 4th position of the offensive line,the use frequency of the fast ball attack is higher,and the overall offensive effect of the back line attack is not good.4.In the defensive counterattack system,the block link,the 2nd and 4th positions are mainly blocked by two people,the single block and the double block in the 3rd place are more,the 4th double block,the 3rd single block effect is poor;the defensive link Left flank,heart,right waist defensive frequency is higher,heart and right waist win,negative defensive effect fluctuates greatly,left waist and left,middle and right rear areas are weak areas of defensive links;counterattack link 4 position strong attack use The most frequent times,compared to the overall offensive effect of the fast ball attack,but the difference between winning and negative attack is greater.5.The technical level regression model has a high degree of fit,and the overall prediction effect is very good.The smash score,the smash error,the serve score,the serve break,the general serve,the block score,the block error,and the serve error are 8 indicators.The important factors affecting the win and negative results of the single game,the smashing mistake,the serve score,and the serve break have the greatest impact on the game.6.The tactical level regression model has a general fit,and the overall prediction effect is ideal.The total number of serve in the left rear area,the effective number of the right waist,the total number of attacks on the 4th position,the effective number of the 2nd block,and the anti-reverse 4 position.The number of strong attack scores and anti-fastball attack scores are six important indicators.It is an important factor that affects the single-game winning and negative results of the game.The effective number of the right-wing and the number of anti-fast-ball attack scores have the greatest impact on the game.
