Новый подход в изучении взаимосвязи функциональной подготовленности и электрогенеза у спортсменов с использованием эталонного кардиоцикла

Abstract

In modern sport, the result depends on many aspects, including technical, tactical, physical, physiological and psychological factors, as well as heredity and fitness athletes. Diagnostics functional status and identification of mechanisms of formation of the adaptive response of the organism to the load allows to analyzing these factors for individual components. Well known, the myocardium is sensitive the indicator´s ability to consume oxygen, which can be a limiting factor in aerobic functional capacities and reserves not only of the heart muscle, but also the entire body. With this increasing needs of the myocardium in oxygen, including under increasing load, lead to ischemic disorders, in the event which suffer all the processes of membrane electrogenesis: excitability of myocardial cells, bioelectric automaticity processes in the myocardium, including the processes of de - and repolarization. It is found that the original features of the reference cardiocycle (EC) single-channel ECG that can be computed in hardware-software complex FAZAGRAF® with finger electrodes have an additional diagnostic value in quantifying the level of the functional state of the myocardium EC, which is formed in the time domain to the coordinates of the averaged phase trajectory and main traditional ECG signs doesn’t depend on the lead systems may reflect the characteristics of electrogenesis. The high degree of single-channel correlation indices EC ECG with quantitative values ​​of functional training athletes (power, economy and effectiveness) allows to use EC in the diagnosis of functional disorders of cardiac hemodynamic to identify units in need of rehabilitation, correction and optimization.
