The variation pulsometry correct indicators` modeling in volleyball players with mesomorphic somatotype depending on the anthropometric features of the organism

Abstract

Annotation. Appropriate cardiointervalographic parameters establishment, for highly skilled athletes of a particular sport, is relevant and can be used for diagnostic purposes and because of connection with the widespread prevalence of cardiovascular pathology. The purpose of the work was to construct regression models of the variations of the pulsometry in volleyball players of the mesomorphic somatotype, depending on the features of anthropometric indicators. The study involved 24 volleyball players with a high level of sportsmanship (from the first adult category to candidates for the master of sports), aged 17–21 years. We carried out anthropometric research by Bunak's method (1941), somatotypological - by the calculated modification of the Heath-Carter method (1990), determination of the component composition of the body weight by the method of Matejko (1992) and cardiointervalographic examination using a computer diagnostic complex “OPTW” following the recommendations of the European and North American Cardiac Association [1996]. The following indicators of variation heart rate were determined: moda, moda amplitude, average minimum and maximum R-R intervals, and variation range. The mathematical models were constructed in the “STATISTICA 5.5” package for Windows using direct stepwise regression analysis. The article presents the results of regression analysis for determining the dependence of variation heart rate indicators in volleyball players of mesomorphic somatotype on the total complex of constitutional characteristics. Mathematical models for determination of individual proper cardiointervalographic parameters based on features of the external structure of the body of youth volleyball players of high level of sportsmanship. The analysis of constitutional predictors that determine the variability of indicators of variation heart rate in a group of volleyball players of mesomorphic somatotype has been performed.
