Mathematical modeling of shin regional blood circulation parameters in mesomorf somatotype wrestlers

Abstract

Morpho-functional parameters of the cardiovascular system, particulary regional hemodynamics, are used to assess the adaptive capacity of the body and predict sports performance. The aim of the study was to determine the influence of external body structure indicators on regional blood circulation indicators in the shin in wrestlers of the mesomorphic somatotype and to build mathematical models to determine the appropriate values of rheovasographic indicators. 61 athletes from freestyle and Greco-Roman wrestling, lightweight and middleweight categories participated in the comprehensive examination. To determine rheovasographic parameters of the shin, tetrapolar rheography was utilozed using a computer diagnostic complex, and anthropometric dimensions were measured according to the recommendations of P. P. Shaparenko (2000). The scoring of the endomorphic, mesomorphic, and ectomorphic components of the somatotype was carried out using a calculated modification of the Heath-Carter method (1990). The results of the study revealed that 40 wrestlers had signs of a mesomorphic type of constitution. Mathematical modeling was carried out using the certified program “Statistica 5.5” using step by step multivariate regression analysis. The total influence of 53 anthropo-somatotypological parameters on 18 rheovasographic indicators of the shin in wrestlers of the mesomorphic somatotype was determined. Mathematical models with an accuracy of describing rheovasographic parameters (ranging from 62.33% to 97.24%) were constructed for 8 indicators. The models we have created can provide an opportunity to determine the appropriate values of these parameters of regional blood circulation in the shin in wrestlers of mesomorphic constitution type using their own anthropometric dimensions.
