Reshetnyaк O. Reaction of the cardiovascular system of sportsmen on the physical load depends on the level of content of micro- and macroelements nutrients in an organism

Dissertation is devoted to the research of a the role of cadmium, calcium and potassium in determination of the functional state of the cardiovascular system and features of its reaction on the physical load in sportsmen and physically untrained boys on the urbanaized territory. The research of the element balance of students revealed that study of chemical elements in the organism of sportsmen was more satisfactory, than for the physically untrained students which showed the deficit of essential elements. The research of features of reaction of the cardiovascular system on the physical loading showed that physiological role of toxic cadmium for the state of the cardiovascular system, was more expressed for sportsmen, than for the physically untrained students, though its content in an organism was within the limits of the existing norm. In the conditions of the deficiency of essential calcium and potassium in the organism of the physically untrained students dependence of the functional state of the cardiovascular system and its reaction on the physical load with the level of these elements has the expressed character both from the side of performance of heart indicators and haemodynamic parameters.
