Method of quantitative assessment of technical and tactical actions in the competitive activity of athletes on table tennis

Abstract

Aim : theoretical substantiation and development of a technique for processing the statistical data of the table tennis match. Material and methods. The study was conducted at the Kharkiv Table Tennis Club Impulse. A video shoot of a match between two athletes was performed using a regular camera of the smartphone. The statistics of the game were analyzed using the technical techniques and positions of the tennis players at the gaming table, at what distance and in what direction the receptions were performed. Results. The automated processing of information on technical and tactical actions in the competitive activity of athletes from table tennis has been developed, substantiated and implemented in practice. Models of multiple linear regression between the degree of influence of the used technical elements for athlete 1 and the value of the number of points scored per match are made. The high significance of the technical elements of Knack (wins,%) and Scratches (wins,%) in the number of points scored per match is shown. The latest figures were significantly unimportant and with very small coefficients. The regression equation is obtained, which allows you to predict the number of points scored in the party, as well as to identify the most influential elements for the player. Conclusions . The automated calculation of the statistics of video shooting of the match is carried out, where the effectiveness and reliability of the main strikes, which determine the effectiveness of competitive activity in table tennis, is objectively reflected. Displays in the form of diagrams of quantitative assessments of technical and tactical actions in the competitive activity of athletes from table tennis. It is aimed at increasing the effectiveness of tennis players, by identifying their weak and strong points, eliminating them, or vice versa, more frequent use in competitions. The method of processing match statistics in the Excel program is developed, substantiated and implemented in practice. The practical value of the technique is in the availability for most players to apply the proposed method on their own.
