Formation of doubles and mixed categories in badminton using multivariate analysis methods

Abstract

The purpose of the this study work is to experimentally substantiate the use of multivariate analysis methods for creating doubles and mixed categories in badminton by, taking into account the physical, technical, and psychophysiological capabilities of 14–15-year-old badminton players aged 14-15 years. Materials and methods. This e experimentstudy involved 14–15-years-old badminton players from of the WBC sports club (age 14-15): girls (n = 10), boys (n = 10). The experiment study was performed carried out induring the preparatory period in, September 2019. The Testing of athletes were tested in terms of physical readiness (100 meter m run, shuttle run 4 × x9 meterm shuttle run, bending of the arms in a lying position, jumping rope, pulling up on the bar, forward bending of the body from a sitting position, long jump from a place) and, technical readiness (stuffing shuttlecocks by open and the closed side of the racket in 1 minutemin, mistakes when filling shuttlecocks, hitting shuttlecocks from the wall in 1 minutemin, and mistakes when hitting shuttlecocks from the wall). To determine the psychophysiological state of athletes, psychophysiological indexes were experimented withevaluated using the "Psychodiagnostics" computer program, which measured (the speed of a simple and complex reaction in various testing modes). The results of our cluster analysis of testing showed that athletes are were divided into three groups, with similar outcomes for both boys and girls. Clusters were determined according to the degree of "similarity" of athletes in terms of complex testing. Mixed discharges were formed using expert assessment methods. As a result of one-way analysis of variance, a significant difference (p < < 0.05) between the groups in terms of the level of physical fitness of boys was revealed in terms of the level of physical fitness of boys. In girls, the groups significantly (p < <0.05) differed among themselves in terms of physical fitness and psychophysiological capabilities. Our analysis has revealed two ways of forming doubles discharges. The first method, "similarity", is based on the similarity of athletes in terms of the pace of play and, the level of development of physical and psychological qualities. This method is suitable for the formation of men and women doubles, where the athletes are equal and have the same tasks. The second method, "compensation", is where a partner with pronounced leading physical qualities will be suitable for a partner who can compensate for his shortcomings. It is recommended to use rational means and methods of physical and technical training of badminton players at the stage of special basic training for the optimal construction of the training process of athletes.
