Research On The Structural Equation Model Of Technical And Tactical Of The Mobile Attack Of The Top Four Teams In Russia In 2018

With the rapid development of science and technology,the analysis of football skills and tactics is constantly developing,and the single-level research methods have gradually failed to meet the current research.The structural equation model is an important research method in the study of social science.This method is transplanted into the technical and tactical analysis of football,which can well study the relationship between different dimensions of the game and different indicators.This opens up a new perspective for the study of football matches.And this multidimensional,multi-level research method can reveal the characteristics of the football game more deeply and help the coaches understand the factors that affect the progress of the game.At the same time,the World Cup,as the world's highest standard and most competitive football event,is an important window to study and analyze the characteristics and development trends of world football.This research mainly uses the literature data method,mathematical statistics method,questionnaire survey method,logic analysis method,video observation statistical method,through the analysis and analysis of relevant literature materials,and through the expert survey questionnaire to determine the indicators,to construct the initial model,After observing statistics in 23 games of the top four teams of the World Cup in Russia in 2018,the relevant data was analyzed and analyzed.Then the database was substituted into the initial model test,and the invalid indicators were eliminated and corrected to obtain the final model.The main conclusions are as follows:1.The flow offensive structural equation model consists of three dimensions: the moment of defensive transition,the organization of the offense,and the moment of formation of the offensive opportunity.In the initial model,the important indicators of the defensive transition time are the number of defensive defensive players,the number of defending defenders,the opponent's offensive space,and the passable path.The important indicators of the attacking organization are the total number of passes and directions.Passing the ball,passing the ball,transferring the ball,passing the ball,passing the ball,passing the ball,breaking the ball,attacking the attack time;the important indicators of the moment of attack opportunity formation are the number of people who grab the point,the number of defenders forming the defensive,and the offense.Form a strong defensive number.2.The database of position battles and quick counterattacks of the Russia's World Cup top four teams shows that there is a certain difference in the technical and tactical indicators of the two.In the three processes,the number of defenders and defenders in position battles,the number of defenders and defenders,The average values of the player's offensive space,passable path,total number of passes,transfer passes,offensive time,and number of points grabbed are larger than those of quick counterattack.3.The statistics of the mobile offensive tactics and tactics of the top four teams in the World Cup in Russia are good,and Cronbach's alpha reliability is above 0.6,meeting the modeling requirements.4.In the research on the correlation of the mobile offensive skills and tactics indicators of the top four teams in the World Cup in Russia,the ball-breaking,long-passing,medium-passing,short-passing and other indicators are very small.5.The technical and tactical indicators of the two offensive types of the top four teams in the World Cup in Russia can be well verified in the constructed mobile offensive tactics model.In the final model,the defensive transition time is the most important factor in the attacking organization.The strong defensive number is the most effective indicator to measure the pros and cons of the defensive attack.The attack time is the most important indicator of the organization that determines the attack.At the moment of opportunity formation,the number of strong defenders in the positional battle is its most significant indicator,and the number of defenders in the fast counterattack is its most significant indicator.
