Abstract
Introduction. Determining the hierarchical structure of competitive activity in volleyball using the methods of multidimensional mathematical analysis makes it possible to rationally construct structural formations of the annual macrocycle of training qualified volleyball players and increase the efficiency of competitive activity. The purpose of the study is to analyze the structure of competitive activity in volleyball using the methods of factor analysis and determine the hierarchy of its individual components. Research methods: analysis and generalization of data from scientific and methodological literary sources and the Internet, pedagogical observations, content analysis of materials from complex scientific groups and official websites of professional volleyball clubs, the Volleyball Federation of Ukraine and the World Volleyball League, methods of mathematical statistics. The indicators of competitive activity of 45 athletes in 28 official matches were used. Results. Factor analysis methods were used to study the indicators of competitive activity of highly qualified and qualified volleyball players - participants in the official matches of the National Championship (10 games), the Cup of Ukraine in volleyball (8 games) and the World League in volleyball (10 games). The selection of players was carried out according to the procedure for determining the «TOP-15 Rating» of the best athletes in terms of leading technical and tactical actions. The affiliation of the constituent components of competitive activity to a specific group of factors, depending on the value of factor loads, was determined. Conclusions. The results of factor analysis indicate the presence of a certain hierarchy in the structure of competitive activity in volleyball and significant differences inherent in this structure in won and lost matches. The most hierarchically important for the general population of the structure of competitive activity and for won official matches are quantitative and qualitative indicators of receiving the ball from the serve, receiving the ball after attacking and deceiving blows; blocking; the number of points scored; attacking technical and tactical actions from the front and back lines and serving the ball. Regarding the hierarchical structure of competitive activity in official lost matches, the 1-3 groups of factors include indicators of attacking technical and tactical actions from the back line; receiving the ball from the serve, receiving the ball after attacking and deceiving blows; the number of points scored; blocking; errors and fouls. Quantitative and qualitative indicators of attacking technical and tactical actions from the front line and serving the ball, according to the results of factor analysis, are assigned to the last (4th) group of factors.
