Abstract

Echocardiographic examination of 28 untrained and 11 trained young men aged 18-20 was performed. It has been shown that long-term systematic muscular work of significant volume and power contributes to the formation of a specific transformation of structures and functions of the heart with a high degree of lability aimed at ensuring the optimal form of adaptation to muscular work. The significant influence of a combination of systematic physical and psycho-emotional loads on the nature of these changes is proved. There is a clear functional dependence between the level of functional fitness of the body and indicators of structural and functional organization of the heart, namely: the deterioration of these indicators is accompanied by a marked decrease in functional fitness (level of physical performance and maximum oxygen consumption).

Keywords: functional state; adaptation; structural and functional organization of the heart; systematic physical load.
