The purpose of the research is to study the relationship between erythrocyte parameters and their acid resistance in young male athletes and physically untrained individuals.

Materials and methods of research. 30 track and field athletes and 30 young men not involved in sports (control group) were examined. Red blood and hemoglobin profile parameters (red blood cells (RBC) and hemoglobin (Hb) content, mean cell volume (MCV), hematocrit (Ht), mean corpuscular hemoglobin concentration (MCHC), content of oxy- (HbO2), deoxy- (HHb), carboxy- (COHb) and methemoglobin (MetHb)) and parameters of acid hemolysis kinetics (time of hemolysis start (ts) and end (te), hemolysis duration (td), hemolysis peak (tp)) were determined in the subjects. Factor analysis was used to evaluate the interrelationships of the recorded parameters. 

Research results. It was found that hemolysis of erythrocytes begins and ends slightly earlier compared to similar indicators in young men who do not engage in sports (p < 0.05). In the control group, factor 1 included high levels of RBC, Hb and Ht; factors 2 and 3 – Hg, MCHC, ts, tp, MetHb and COHb. Taking into account the signs of the correlations, we can conclude that ts increases with higher Hb concentration and low MetHb content (factor 2), and tp decreases with an increase in the content of COHb in erythrocytes (factor 3). The factor structure of student-athletes indicated that a decrease in RBC, MCV and their MCHC, as well as the accumulation of a deoxygenated form of haemoglobin in the blood, is accompanied by stimulation of erythropoiesis and the release of young, more haemolytically resistant forms of erythrocytes.

Conclusion. Thus, athletes develop stable compensatory reactions in their bodies aimed at maintaining oxygen homeostasis. A decrease in the quantitative parameters of red blood is accompanied by activation of hematopoietic function and the release of young red blood cells into the bloodstream.
