Abstract
Greco-Roman wrestling places high demands on functional training, which determines the further success of tech-nical and tactical training of athletes. The aim is to determine the features of the functional state of the cardiorespiratory system of Greco-Roman wrestlers at the stage of preliminary basic training in the preparatory period. The study used theoretical research methods (theoretical analysis of scientific and methodological literature) and empirical: computer rheography (this device is intended to determine the functional state of the cardiovascular system), computer spirography (this device is intended to determine the functional state of the respiratory system), and mathematical methods statistics. The mean value of vital capacity in the group of wrestlers at the beginning of the study was 2.40 ± 0.04 l, which was 80.78 ± 1.85% of the appropriate values and showed reduced ability to external respiration and chest rigidity. The detailed distribution of Greco-Roman wrestling according to the forced vital lung capacity in relation to the normative values showed that this indicator in the norm was in 26% of subjects, in the conditional norm – in 41%, in 36% of subjects – in a slight decrease. Reduced ones compared to normal stroke volume (45.70 ± 1.41 ml) indicated a decrease in myocardial contractility, and proper values of minute volume of blood circulation were achieved due to increased heart rate, which is not a rational adaptive response in the state peace of mind. Functional training is an im-portant component of the preliminary basic training; the program of its improvement in Greco-Roman wrestling in the preparatory period is an urgent scientific and practical task of modern sport, and the indicators of physical fitness are a prerequisite for developing a program of improvement.
