Application Of Data Volley4 In Technical And Tactical Statistics Of High-level Volleyball Teams Preparing For Large-scale Events

With the rapid development and continuous innovation of modern sports,any sports can not be separated from accurate sports intelligence information.Whether sports intelligence information can be accurately acquired,disseminated,mastered and utilized largely determines the competitive level of a sports event.Therefore,how to collect and use intelligence information quickly,efficiently and accurately has become the main form of competition for high-level teams outside the stadium.In this paper,literature review,mathematical statistics,video analysis,expert interviews and other scientific research methods are used to analyze the technical and tactical statistics of high-level volleyball in preparing for large-scale events.The practical application of Data Volley4 software is expounded,and its practicality and innovation are summarized,and its shortcomings are explored.In this paper,the Data Volley4 software is used to collect and sort out the video data of related competitions,and the technical and tactical analysis is carried out.The statistical system of volleyball techniques and tactics established by the software enriches the statistical analysis methods of volleyball techniques and tactics,and provides a brand-new method and idea for the video statistics and analysis of volleyball coaches at the game scene and after the game,provides data reference and theoretical support for coaches to improve training effect and innovate training methods,and contributes to the promotion of the use of Data Volley4 software in other sports.Finally came to the conclusion:(1)In volleyball competition,if you want to achieve good results,you must start with the preparation before the game.The result of the game is closely related to the adequacy of the preparation before the game.Before the competition,we should know the opponent’s lineup,commonly used offensive and defensive tactics,the characteristics of the main players and substitutes,the specific play styles of each round,etc.,and formulate corresponding strategies in a targeted manner,so as to know ourselves and know ourselves and defeat the enemy.(2)In the competition field,the technical statistics of both sides in the competition and timely communication with the coach seat can quickly obtain important information,formulate tactical deployment and help the team to take the initiative in the fierce competition.(3)After the competition,the data obtained by Data Volley4 software is used to summarize the whole competition,analyze the shortcomings and deficiencies of the team,and find out the gap between the top team and the top team by comparing the data with the top team in the same competition,and seek improvement methods to narrow the gap between the top team and the top team.(4)Data Volley4 software has great advantages in technical statistics,and can achieve excellent results when studying opponents or studying laws.Although Data Volley4 software has many advantages,it is relatively difficult to get started.It takes a long time to enter the game scene synchronously,and the associated video is difficult and the accuracy is not enough.It is difficult to enter the competition scene synchronously with the competition,and the accuracy of correlation between statistical data and video is not enough.
