INTRODUCTION
Typological peculiarities of blood circulation study in healthy population led the scientists to a new point of view concerning cardio-vascular system study [3, 7]. According to the results of works [4] authors define three types of blood circulation: hypokinetic type of blood circulation (HTB), eukinetic type of blood circulation (ETB), hyperkinetic type of blood drculation (HrTB). The base for such kind of division forms heart index (HI). This index is considered to be the main in the characteristics of blood circulation. HTB is characterized by a low HI. In case of HrTB the highest values of HI are determined. In case of the average values of HI the type of blood circulation was called eukinetic. It was stated that the types of blood circulation, defined in terms of relative rest, are able to influence the reaction of an organism in case of physical load [2]. Nevertheless, specialists express contradictory opinions concerning the dependence of reserve capacities, tolerance and efficiency of cardiovascular system activity on the type of blood circulation.
The aim of this research work was the athletes' cardiorespiratory system indices determination in terms of increasing power load, depending on typological peculiarities of blood circulation.
MATERIALS AND METHODS
The choice of methodological techniques and the volume of the research were conditioned by the aim and the objectives of the work. The research work was held in the laboratory of functional diagnostics of "Physical upbringing" department of Kazan State Agrarian University. 105 men at the age of 18-35 took part in the experiment.
According to HI volume athletes were divided into 3 groups according to the types
of blood circulation: hypokinetic type of blood circulation (HTB)- with a high HI value, eukinetic type of blood circulation (ETB) - with the average HI value, hyperkinetic type of blood circulation (HrTB)- with a low HI index. Heart index was calculated according to the following formula: HI= MBV / S, where
HI - heart index,
MBV - minute blood volume, l;
S - body surface area, m2.
Physiological estimation of cardiorespiratory system state was held on the basis of the following indices analysis:
HR - heart rate, beats/min;
CSV - cardiac stroke volume, ml;
MBV - minute blood volume, l/min;
RR - respiratory rate (resp./min);
RC - respiratory capacity (ml, BTPS);
MRV - minute respiration volume (l/min, BTPS).
For CSV revelation differentiated rheogram according to V. Kubechik (1974), in modification of Y.T. Pushkar with the authors (1980).
Minute blood volume was calculated as the product of CSV into HR.
For the indices of external respiration determination we used pneumotachograph.
Statistical results handling was held in accordance with generally adopted methods of variative statistics [1,2,6]. For validity of differences estimation standard values of Student criterion were used.
RESEARCH RESULTS AND THEIR DISCUSSION
In the groups of athletes we revealed three types of blood circulation: HTB, ETB,
HrTB. Most athletes belong to HTB type, 18 had HrTB type of blood circulation. In the opinion of the most authors, who study the types of blood circulation in terms of HrTB heart works in the less efficient regimen and the range of compensatory abilities of this type is restricted. HTB is the most efficient type and cardiovascular system in this case has greater dynamic range. The received results of heart pumping function (table 1) prove different contribution into the value of cardiac output of CSV and HR indices among the athletes with different typological peculiarities of blood circulation in case of increasing power load. At the same time, inotropic heart function was higher in the group of athletes with HTB. It can be considered as the most effective mechanism of urgent MBV adaptation to the load. Among the representatives of HrTB and ETB MBV increase was owing to heart rate frequency. Chronotropic mechanism of cardiac output increase in the group of athletes with HrTB was seen starting from 50 W load, in the group of athletes with ETB starting from 100 W. In case of HrTB adaptation to physical load happens owing to inotropic and chronotropic function of myocardium without Frank-Starling mechanism use. Speaking about HTB, during the physical load Frank-Starling mechanism starts to work, which shows more efficient character of adaptation. F.G. Uglov and other authors (1982) defined the threshold of an adequate hemodynamic reaction, during which CSV increase stops. This threshold in case of 150 W loads was achieved by the athletes with HTB, athletes with ETB in case 100 W load, athletes with HrTB in terms of 50 W load. MRV indices in groups of athletes with hypokinetic, eukinetic, hyperkinetic peculiarities of blood circulation in terms of increasing power load were the same at all levels of work at cycle ergometer, independent of the type of blood circulation (table 2). However the value of MRV in different groups of respondents was achieved using different combination of RR and RC indices. In the groups of athletes with ETB and HTB there was infrequent respiration,
which was compensated by high RC indices, which shows efficient activity of external respiration apparatus. In the group of athletes with HrTB at all stages of the load there was more intensive breathing with low RC indices.
All types of cardiorespiratory system adaptation are presented in the group of athletes with hypokinetic peculiarity of blood circulation, in the group of athletes with eukinetic peculiarity of blood circulation there is no respiratory type of cardiorespiratory system adaptation, in the group of athletes with hyperkinetic peculiarity of blood circulation there is no respiratory and inotropic-respiratory types of
cardiorespiratory system adaptation.
With the power of the fulfilled work increase at bicycle ergometer differences in HR indices between the groups of athletes with different typological peculiarities of blood circulation level up. However, such kind of differences in HR values stay between the groups of athletes, which present different types of cardiorespiratory system adaptation. Thus, the type of adaptation influences HR indices independent of power of the fulfilled load. It can be explained by the fact that typological peculiarities of blood circulation are defined at the state of rest and the types of cardiorespiratory system adaptation are defined in case of physical load. That is why such kind of changes take place in HR indices during the increasing power load fulfillment at bicycle ergometer.
Valid differences in CSV indices between the groups of athletes with hyper-, eu- and hypokinetic peculiarities of blood circulation were demonstrated in case of inotropic type of adaptation and in terms of 50, 100 and 200 W loads. The highest CSV indices were in case of inotropic type of cardiorespiratory system adaptation in comparison with other types of adaptation. The exception was the group of athletes with inotropic-respiratory type of adaptation, when in terms of 100, 150 and 200 W loads there were relatively high indices of CSV. It proves the expediency of dividing athletes into the types of cardiorespiratory system adaptation.
