Research On The Data Analysis Of U14 National Team During The "Wuhan Cup"

The level of youth training can reflect the development of a country’s football career to a certain extent,and determine the future of a country’s football.The U14 national junior team of Chinese men’s football team is the youngest national brand team at present.Its training level and performance represent the highest level of Chinese football players of this age.It is an important way of feedback in sports training to record the physical changes and on-the-spot behaviors of athletes through data and to conduct comprehensive analysis after competitions.Data analysis is the objective collection and classification integration of the team’s daily training and competition information.It can provide scientific feedback for coaches and athletes,so that coaches and athletes can understand the team and players more objectively,so as to improve training and sports performance.This paper uses the methods of literature,expert interview,questionnaire,video analysis,on-the-spot investigation and mathematical statistics to study the data analysis of U14 national youth team of China during the "Wuhan Cup International Youth Football invitational tournament".Based on the data,this paper mainly draws the following conclusions:The current data analysis work of China youth team can collect the basic information of coaches and players,but there are some deficiencies in the information storage and management.With the flow of players and the replacement of data analysis workers,data analysis work has no continuity in the storage of information,and can not achieve the accumulation of all kinds of data and information of players,which is not conducive to the establishment of team database.The current data analysis work of the national team is mainly the communication between the team data analysis workers and coaches,ignoring the needs of the players themselves for the data,unable to communicate the data to each player in the first time after training or competition.After players get data,data analysts and coaches lack feedback from players.The current data analysis work of the national youth team can collect and analyze the data of athletes from two aspects of body shape and sports quality,but it lacks the detection of the physical function of players.The current data analysis work is effective in the analysis and application of high-intensity running distance.In terms of sprint times index,the current method can analyze the performance of single player,multiple players and the team as a whole from multiple angles,but the number of sprint times collected by existing equipment can’t mark each sprint.In terms of players’ heart rate load,the current method can provide coaches with players’ real-time heart rate,which can be used to evaluate the physical condition of players by reference to the average heart rate after the game.However,it is unable to start and stop the real-time recording of players’ heart rate according to the situation on the field.In the collection and analysis of the shooting index of the team,the current scheme can provide information for the team from shooting times,shooting positive times and scoring rate,which is effective in the application of shooting index.In terms of the team’s passing index,the current data analysis work can make statistics and brief analysis on each player’s forward,backward,horizontal passing,short passing,long passing and medium distance passing.However,the efficiency of data collection and analysis by a data analyst is low,and the analysis stays on the surface,which is difficult to be in-depth.Coaches do not put forward requirements to team data analysts for specific technical and tactical indicators,which leads to data analysts not having pertinence in team technical and tactical indicators collection and analysis.
