Relationships of the amplitude indicators of the rheovasogram of the thigh with the parameters of the external body structure in trackathletes-sprinters with the ecto-mesomorphic type of constitution

Abstract

Abstract. Determining the state of peripheral hemodynamic indicators is one of the modern challenges, which can be a barrier for athletes of a particular type of sport of a certain somatotype in relation to individual constitutional features and prevent achieving sports results. The aim of the work was to study the relationship between the parameters of the rheovasogram of the hip with anthropometric dimensions and components of body weight and somatotype in track and field athletes with a high level of mastery of the ecto-mesomorphic somatotype. We conducted a study of high-level sprinters using the method of P.P. Shaparenka where 50 anthropometric body sizes were determined. The component composition of body weight was carried out using the Matejko method, and the Heath-Carter method was used for score assessment of the somatotype components. It was determined that 28 track and field athletes belonged to the ecto-mesomorphic constitutional type. Rheovasographic indicators of the thigh were measured on a computer diagnostic multifunctional complex by using tetrapolar rheography. Correlation analysis was performed using Spearman’s non-parametric statistical method in the STATISTICA 5.5 program. It was established that in sprinters who belong to the ecto-mesomorphic somatotype, there are numerically reliable correlations between the amplitude parameters of the hip rheovasogram with anthropometric dimensions and somatotypological indicators. The greatest strength and number of relationships was seen between between longitudinal, girth, transverse, body dimensions, the thickness of skin and fat folds, components of somatotype and body weight and basic impedance, amplitudes of the systolic wave and rapid blood filling, where the average strength of the connections prevail. The characteristics of the relationship between the amplitude indicators of the rheovasogram of the thigh and the indicators of the external structure of the body, which we determined, confirm the conditioning of the indicators of peripheral hemodynamics by constitutional features.
