Current data on stress cardiovascular function in functional and metabolic ready state of young sportsmen increasing endurance

We should make special mention of publications over the past decades which have been chosen from many published works on the designated problem [4]: athlete's heart, stress cardiomyopathy and fundamental research of Z.B. Belotserkovky and B.G. Lyubina “Cardiac Function and Functional Preparation of a Sportsman (normal and atypical states)” [1]. Within the past decades we have examined the polyfunctional cardiovascular system and detected its regulatory mechanisms. The research objective was not only the clarification of the obtained literature data, own study materials, but also the interpretation of cardiovascular regulatory mechanisms depending on age and qualification-related characteristics of sportsmen who live in the Ural megacity. People increasing endurance in such sports where they can't reach the international level as swimming, running, cross country skiing, orienteering have been examined.
