Research On The Basic Unit Athletic Course Of Male Single Items Of Bat Holding And Net Separating Competitive Items Group

Bat holding and net separating competitive items are included in net separating competitive items group of technique leading. Compared with other net separating items, the characteristics of their technical actions, hitting types, competition forms, competition course, laws to overcome, etc. are closer. Besides, among bat holding and net separating competitive items, table tennis and badminton are our country's traditional advantageous items and tennis, which is lagged behind and is emergent to exploit, lies in the inferior position. It has high scientific value and objective feasibility to bring these three items into one category and explore the objective laws of their athletic course.Adopting the methods of looking up literature, interviewing experts and mathematical statistics, this paper statistically analyzes the video recording of all kinds of international competitions of male table tennis, tennis and badminton players of high level, explores the operating model of their basic unit athletic course and achieves the results as follows.The match of the sport items of bat holding and net separating competitive items group are composed of players' contest of both sides for every point. We call the competitive course for one point the basic unit athletic course. There is a basic unit athletic course with specific structure and stage characteristic during players' contest of both sides for each point. The basic unit athletic course is composed of players' service and receive tactics system of both sides of contest.Through the theoretical research on the basic unit competitive course of bat holding and net separating competitive item group, this paper systematically describes the organization structure, the stage characteristic and the multiple hits structure of the basic unit athletic course. On the basis of that, this paper puts forward the theory and method to analyze the characteristic of players' technical application and the theory and method to evaluate and diagnose players' ability of tactics during the basic unit athletic course and the analyzing method of the factors to win of the players of both sides in a match and then, provides a theory and method system to reveal the objective laws of the basic unit athletic course of bat holding and net separating competitive item group.The hits distribution characteristics of the basic unit athletic course of male single items of bat holding and net separating competitive items groups appear as that:The distribution of the basic unit athletic course of each sport item presents the positively skew distribution;The efficient distribution region of the basic unit athletic course is the first to the seventeenth hit for table tennis, the first to the twenty-first hit for tennis and the first to the twenty-sixth hit for badminton separately.The peak value of positively skew distribution is the fourth hit for table tennis, the second hit for tennis (the corrected value is four hits.) and the fifth hit for badminton separately.70% of the concentrated distribution region of the basic unit athletic course if the first to the seventh hit for table tennis, the first to the ninth hit for tennis, and the third to the eleventh hit for badminton separately.The average hit frequency of the basic unit athletic course: table tennis, tennis and badminton are different from each other.The laws of winning or losing points of the basic unit athletic course of male single items of bat holding and net separating competitive items group appear as that:Although table tennis, tennis and badminton similarly belong to the bat holding and net separating competitive items group and their basic unit athletic course are all part of the stage division theory, their laws of winning or losing points have different characteristics.Players' first four hits of both sides are the focus of offense and defense in table tennis matches.The key of victory or defeat lies in players' contest of both sides during the stage of stalemate in badminton matches.In tennis match...
