Research On The Fluctuations Of Scores In High-level Women's Volleyball World

For every web item-group,volleyball volleyball competition against phenomenon is against the two sides in various forms in the process of the obtained in the training of competitive ability,but individual athletes or team can keep ultra high competitive ability in the normal competition,competitive performance inevitably there will be a phased "fluctuation" phenomenon.Volleyball is limited to the number of points of the game,the performance of the performance of the stage of the "fluctuation" phenomenon can be reflected by the score.Based on the 4 th Olympic Games as the statistical object,studies the distribution characteristics of fluctuation and the score score fluctuation exists between the competition law,further to the world high level fluctuation phenomenon analysis research,through quantitative analysis,find out the fluctuation phenomenon,the advantages of technology and tactics for the score of the game when phase select the corresponding tactics and technique style changes,according to the score to a great extent fluctuation law to adjust the tactical methods,choosing suitable way of scoring,extend the tide stage,shorten the tide phenomenon,the final success.In this paper,the author makes a quantitative analysis of the rise and fall of women's volleyball matches in the world and the causes of technique and tactics by means of literature,statistics and mathematical statistics,and draws the following conclusions:1,high level team in the score fluctuation phenomenon,women's volleyball competition tide phenomenon of significant differences ratio,winning teams in the American Q,H period of stalemate,runoff rate have significant difference,winning consecutive scoring advantage;2.According to the score of each bureau,the combination of tide,tide and ebb tide is carried out,and the winning combination is obtained by combining the number and proportion of the winning combination.Tidal rise-tidal flat-tidal rise model,tidal rise-tidal flat-tidal-rise model,etc.3,the high level volleyball match score fluctuation competition process analysis,the 4 th Olympic Games tide phenomenon points race level structure in 3-4 level structure in the highest frequency,overall competition process is not balanced,through the statistical analysis,accord with normal distribution.4,high level in the world women's volleyball match points in the process of competition tactics link analysis,the tide stage mainly happens on the points before 8 tactics link of the process of competition,the service that the server,the first and second LanFang counter low false positives,there are differences,to link the three tactics as scoring advantage;The receiver has a scoring advantage in the attack and the third stop.5.In the analysis of the technical causes of the fluctuation of the world high-level women's volleyball match,the deduction is the main scoring method,blocking and serving as the secondary scoring means.Each technology is different in nature,effect and way.6,the high level volleyball technique play using phase fluctuation,storm tide stage utilization rate is highest,accounted for 50.73%,the fast break times,fast ball cover attack and stereo capture ratio is relatively small;In the statistics of the effect of the tactics of the surge stage,the highest scoring rate is the fastball cover and the scoring rate is higher.
