MODELING OF THE BIODYNAMIC STRUCTURE OF A VOLLEYBALL PLAYER'S MOVEMENTS DURING A FOREARM PASS PERFORMANCE

Abstract

The article presents the results of studying the biomechanical characteristics of the supporting reactions of the volleyball players body during a forearm pass performance. Graphic models of the biodynamic structure of the volleyball players movements (players of various positions) were constructed. It has been proven, the higher volleyball pleyers athletic skills are the greater the value of the power indicators of support reactions is, also the shorter time required to perform the game technique. Goal. Identify the features of the biodynamic structure of volleyball players' movements (players of the 1st category and Candidates for Master of Sports) during a forearm pass performance.

Methodology. Theoretical and empirical methods such as: comparison, generalization, tensodynamometry, modeling, mathematical method, as well as statistical methods were used to achieve the research objectives.

Scientific novelty. The features of the biodynamic structure of volleyball players movements during a forearm pass performance, depending on the sport category, have been determined.

Conclusions. During a forearm pass performance by volleyball players, it was determined that the higher sports qualification is the more value of biodynamic indicators increases, but time indicators decrease. According to the correlation analysis, among the registered indicators of the volleyball players (1st category and Candidates for Master of Sports) the 143 and 205 significant.

As a result of correlation analysis, graphic models of the biodynamic structure of volleyball players movements for each sports category were constructed. The largest number of significant correlations of indicators in female volleyball players (specifically Candidates for Masters of Sports) is the maximum repulsion force relative to the vertical axis and the maximum value of the vertical components of support reactions. Meanwhile for the first category female volleyball players, it is TPS. The presence or absence of interconnections between individual indicators of the biodynamic structure affects the choice of training tools used to improve the training process and control methods. The absence of significant interconnections suggests the search for means of directed influence, while their presence allows the use of integrated exercises. As a result of the study, it was determined that the significance of individual indicators of the biodynamic structure in the effectiveness of performing specific techniques varies depending on the volleyball players category, which is accordingly related to the peculiarities of their motor skills formation.

As follows, it can be noted that the biodynamic structure of movements during a forearm pass performance by volleyball players of different qualifications has its own characteristics. The higher category of the player is the more likely strength indicators come to the fore. The constructed graphic models of the biodynamic structure of movements can be considered as a reference for Candidates for the Matters of Sports and first category volleyball players. The obtained data, based on the identified patterns of rational organization of the biodynamic structure of motor actions, allow us to analyze and improve the level of volleyball players performance. Prospects for further research on the outlined topic consist of further research the biodynamic structure of movements of female volleyball players depending on the performance of various techniques.
