Quantitative Analysis Of The Phenomenon Of "Fluctuation" In The Scores Of World High-level Women’s Volleyball Matches

The performance of the competitive performance system changes at any time.When the change exceeds a certain threshold at a certain time,the change is amplified,showing that one side of the competition is in the "up" phase and the other side of the competition is in the "down" phase.The factors change,and the internal factors of the competitive performance system of the two sides of the competition will seek a new stable state.At this time,the two sides of the competition will be in a flat phase.With the change of the stimulus factors,the two sides of the competition will always be in a balanced state to an unbalanced state.The state of balance evolves repeatedly,and it is finally reflected in the "fluctuation" of the score in the game.This article uses the literature method,technical statistics method,and mathematical statistics method to analyze the characteristics and causes of the phenomenon of "fluctuation" in world high-level women’s volleyball competitions,and draws the following main conclusions:Research on the characteristics of the "fluctuation" phenomenon of the World Cup women’s volleyball competitions shows that the phenomenon of "fluctuation" of the world’s high-level women’s volleyball competitions has a periodical characteristic,which has different performances in different innings and scores in different innings The temporal characteristics of the "fluctuation" phenomenon are: the occurrence rate of the "flicker" in the basic round is higher than that in other rounds;the absolute frequency of the "fluctuation" at the match point is higher than in other rounds;The average of the absolute length is the highest;the strength of the "fluctuation" of the score in the tiebreaker is higher than that of other innings;under the structure of 70%,the "fluctuation" of the scores of the women’s volleyball team in different innings of the World Cup is 6 The length of the competition unit is relatively concentrated and the absolute frequency appears up to 29 times.The spatial characteristics of the "ups and downs" phenomenon of the winners of each round of the world high-level women’s volleyball match are as follows: the starting structure of different rounds of the game is P-phase to Z-phase or Z-phase to P-phase structure,and the end of different rounds The spatial structure of is mostly expressed in the Z → P combination structure ending in P and the structure ending in Z.In the basic opening,the P → Z structure mainly exists in the middle and front sections of the game.The opening Z → P structure and the ending Z → P structure mainly exist in the middle and back sections of the game,and the ending Z mainly exists in the middle section of the game.At the match point,the opening P → Z structure exists in the front and back of the game,the ending Z → P structure mainly exists in the middle and back of the game,and the ending Z structure mainly exists in the front.At match point B,the opening P → Z structure mainly exists in the front section of the game,the ending Z → P structure mainly exists in the middle and front section of the game,and the ending Z structure all exists in the middle and back section of the game.In the final game,the P → Z structure mainly exists in the middle of the game,the opening Z → P structure mainly exists in the latter part of the game,and the ending Z structure all exists in the middle and front part of the game.When studying the cause of the "fluctuation" in the scores of high-level women’s volleyball competitions in the world,the key technical and tactical factors affecting the phenomenon of "fluctuation" in the scores of high-level women’s volleyball competitions in the world are taken as the starting point.For: average serve,serve break,serve score,receive serve in place,receive service not in place,no attack,serve error,storm attack,offensive score,offense blocked,offensive error,block error,block,block,defense In place,defense can attack and defensive mistakes.
