| The World Cup is the world's highest level of football matches,is the world's soccer power to express their level of football platform.The team in the world cup is the best team eliminated from the qualifying game,showing the most advanced football technology and tactical play.2014 Brazil world cups are the latest World Cup competition.This study of the world cup in offensive and defensive technical indicators of statistical analysis,has important significance and value.This study to Brazil for the 2014 World Cup 32 teams as the research object,using the method of literature and mathematical statistics,the 2014 Brazil World Cup game offensive and defensive technical indicators of the to carry on the factor analysis,establish attack technology of structural equation model,to explore the relationship between offensive and defensive technical indicators.The results of this study are as follows:1.2014 Brazil World Cup 32 teams nine offensive operation index of maximum 5 from the German champion team,three from runner up Argentina,were distributed in four games,the distribution is relatively dense;nine defensive technical indicators of the highest value 6 from missed the final eight teams,three from to secure fourth place Brazilian team were distributed in seven games,distribution is relatively fragmented.2.2014 World Cup in Brazil attack technical indicators and control ball time,attacking threat,number of passes,the shot number,number,running away from the ball,passing success rate,scored the front 30 m number etc.eight indexes are the existence of the relationship between,and goal number and shot number,number,running the ball distance between exist correlation.There are 9 pairs of indicators of the odious technical indicators are highly related.Only 8 of the defense technical indicators are linked to the indicators,and there are only 1 pairs of defense technical indicators which are highly related.3.2014 Brazil World Cup 32 teams attack technology factor include: control competition factor,making scoring opportunity factor,scoring an ability factor;defensive factor includes: running back job factor.Rescue factor tackles,foul factor,stop scoring factor.4.The 2014 World Cup in Brazil in 32 teams team offensive and defensive technology of structural equation model after correction,the model of x2 / DF values were greater than 1 and less than 3,RMSEA were less than 0.08,the fitting index RMSEA,GFI,AGFI value were greater than 0.90,said model has better fitting degree.5.2014 World Cup in Brazil attack equation model constructed latent variables: control of the game and create scoring opportunities,the ability to score between relations,in control of the game to create scoring opportunities,the control competition on the effect ability to score goals and create scoring opportunities to score values were 0.47,-0.30,0.71,defensive structure equation model constructed latent variables: running against rob,rescue tackles and fouls,fumble between relations,running back rob to rescue to tackle and rescue tackles to foul,rescue tackle on goal effect value were 0.73,0.61,-0.25.Depending on the results of the above research,we can draw the following conclusion: the link between the invasive technology of the world cup is larger,the team can get more chances of passing or shooting through the control game.Reduce blind,increase shooting times more conducive to achieving goals;smaller and between the defense technology,the team through actively running against robbery can increase in the number of clearances,tackling.The use of rescue,tackle technology can reduce the number of goals of the team,the team will also increase the number of fouls. |
