RESUMO
The purpose of the paper is to study and analyse the annual dynamics of blood lipid parameters in highly qualified physical training. An experiment is a leading method for studying this problem that allows considering the problem comprehensively and in practice, as well as a comparison method, which makes it possible to analyse common features and differences as well as consider the dynamics of blood lipid parameters. Athletes who developed endurance or strength to a greater extent had no significant differences in many blood parameters. However, the groups of athletes who developed only strength had a more pronounced anisocytosis. In addition, it was possible to identify a correlation between the parameters of red blood cells and trained sports results. It was concluded that the highest indicators of the number of red blood cells, haemoglobin and average haemoglobin concentration in red blood cells were observed in strength training, and the lowest-in athletes training speed indicators. The article is of practical value for future research in the field of medicine and regenerative physiotherapy.
