Research On The "fluctuation" Phenomenon Of The Top 6 Players In The Chinese Women's Volleyball Super League In The 2020-2021 Season

In the Chinese women's volleyball Super League in the 2020-2021 season,after fierce competition among 13 teams,Tianjin team,Jiangsu team,Shanghai team,Guangdong team,Shandong team and Liaoning team finally won the top 6 in turn.By using the methods of literature review,video observation and mathematical statistics,this paper makes statistics on the scores of the top six women's volleyball teams in the2020-2021 season of China Women's volleyball Super League and the application effect of techniques and tactics in each stage,studies the phenomenon of "fluctuation" in the competitive level of China Women's volleyball Super League and its causes,and analyzes the relationship between the exertion of individual,collective and opponent's technical and tactical abilities and the success or failure of the team Finally,it puts forward the strategies to deal with the "fluctuation" phenomenon,which can provide reference for the future training of Chinese women's volleyball team.The conclusions are as followsThe results show that: 1.Most of the top six women's volleyball teams in the Chinese Super League play similar in the competitive stage.The proportion of the winning Z segment in the whole competitive unit is high,and the proportion of the losing l segment in the whole competitive unit is high.The higher the ranking,the more obvious the characteristics of the team.The proportion of winning and losing in P segment is also higher.2.The frequency,length and strength of Z segment in the winning game are significantly higher than those in the losing game,while the frequency,length and strength of L segment in the losing game are higher than those in the winning game.The frequency,length and strength of P segment are similar in the winning and losing games.The top three teams in the winning Z segment frequency and the losing l segment frequency are significantly higher than the last three,and have this characteristic in length and strength.3.In the "fluctuation" stage,the frequency of ZLZ is the most in the winning game,and LZL is the most in the losing game.In the index characteristics of competitive length,the length of competitive unit and the proportion of the dominant period in the winning game are higher than those in the losing game.In the losing game,the length of L segment is longer and loses more points,which becomes the main structure of the losing game.4.The winning start and end are mainly Z,and the losing start and end are mainly L.but in the last three teams,the probability of Z segment appearing at the end of the losing start is also higher.4.The opening and ending of the winning game is mostly based on Z,and the opening and ending of the negative game is mainly based on L.However,among the lower three teams,the probability of Z phase appearing at the beginning and end of the negative game is also higher.
