Object: To conduct a comparative analysis of changes in the biochemical parameters of blood in athletes of various specialties of athletics, for the correct planning of the training process and the selection of funds. Findings The experiment showed that regardless of the specialization, all athletes had changes in the average values of the studied peripheral blood parameters, especially an increase in the level of lactate, which reached the maximum values with the interval method of the training process in short and medium distance runners, and the pace load in athletes specializing in sports walking. In shot putters and all-rounders, the changes in blood parameters from the initial ones were lower. Conclusions: The optimal level of lactate concentration for the development of strength endurance is above 6 mmol/l. For high-speed endurance training (short and medium distance running), the lactate level should be at least 8 mmol/l. With prolonged maintenance of lactate levels above 11 mmol/L, acidosis of muscle cells and intercellular space occurs, as evidenced by a more noticeable decrease in blood pH.
