The article presents the results of the study concerning the adaptation of a speedskater`s body to intense physical exertion during certain intervals of a one-year macrocycle. The study involved athletes belonging to the "youth" age category (14-15 years old), training at all distances of all-round events (500 m, 1000 m, 1500 m, 3000 m), as well as male sprinters and male all-rounders of 20-26 years old specializing in running short (500 m, 1000 m) and long distances (1500 m, 3000 m and 5000 m) respectively. The article shows that the analysis of certain biochemical blood parameters, in particular hormones and metabolites, in the presence of hyperkinetic stress during the training activity of sprinters and all-rounders at the general preparatory stage, allows minimizing negative consequences in the form of fatigue. The article indicates that the competent management of maladaptive processes in speed skating at the beginning of a one-year macrocycle determines a qualitative increase in sports results in the future.
