Study On The Stage Performance Of Chinese Men's Volleyball Competition In 2018 World Men's Volleyball League

A series of information will be generated in the process of competitive sports competition,which can reflect the inherent characteristics and winning rules contained in this sport to some extent.Due to different times in the process of sports game technique using both the athletes' physical,mental,and so on will change periodically,and the judgement of command of the coaches,referees and match various uncertain factors in the process of mutual influence,even if is the world's top athletes,their own and the team is difficult to do in the game has remained highly competitive level,will be hard to avoid can appear fluctuation of athletic performance,also known as periodic "fluctuation" phenomenon of athletic performance,in the volleyball match is in the form of gain and loss of stage.This study takes the competitive performance of Chinese men's volleyball team in2018 world men's volleyball league as the object of study,and USES literature method,video observation method,mathematical statistics method,logical analysis method and other research methods to reveal the general rules of staged competitive performance of Chinese men's volleyball team from a micro perspective.This study firstly makes a comparative analysis of the non-technical factors of Chinese and foreign men's volleyball teams,and then divides the competition of Chinese men's volleyball teams into stages of Z(rising tide),P(leveling tide)and L(falling tide),and then groups them into different win and loss games,different rounds and different achievement groups,and obtains:1.There is still a certain gap between Chinese men's volleyball team and European and American teams in terms of body shape.The Chinese men's volleyball team has the advantage in facing most opponents in the spike height and block height.In terms of age and competition experience,the Chinese men's volleyball team is a young team.2.in the winning and losing game,the competitive characteristics,the winning game in the whole game is easy to occur leveling tide,rising tide phenomenon,negative game is easy to appear leveling tide,falling tide phenomenon,the winning game in the leveling tide,rising tide stage after many competitive units,the proportion is high,for the negative game to reverse the difficulty is an important factor in losing the game;In terms of points gained or lost,serving is the short board of Chinese men's volleyball team,and spiking isthe main scoring method of Chinese men's volleyball team,which is also an important factor of points lost.Good blocking can accelerate the entry of rising tide stage and extend the time of rising tide stage after entering rising tide stage.The stability of the first pass is the key to reducing points lost.3.Different times,in terms of characteristics,the relative frequency of rising tide,leveling tide and falling tide in different game times is different.The relative frequency of tiebreaker in rising tide and leveling tide is higher than that in basic game and match point game.In terms of points,spike is the most powerful scoring weapon and block is the most effective defense.Good serve can drive the attack and defense of the whole team.In the aspect of losing points,the instability of passing has become the biggest reason for the Chinese men's volleyball team to enter the leveling tide and falling tide stage,and too many service errors have also become an important reason for the decline of the Chinese men's volleyball competitive performance.4.Different groups,in terms of characteristics,there were significant differences in the absolute frequency and intensity between the three groups in the rising tide stage,and no significant differences in other characteristic indexes.In terms of points gained or lost,when Chinese men's volleyball team faced a strong opponent,as the opponent was relatively strong in attack and defense,the blocking effect of Chinese men's volleyball team was not obvious.In the face of a relatively weak opponent,Chinese men's volleyball team had more attacks in spiking,but more mistakes in spiking followed.
