Annotation:
Physical exertion in sports triggers a systemic reorganization of the body’s regulatory mechanisms, which occurs through neuroendocrine and immune interactions and leads to the development of long-term functional adaptation. During adolescence, when growth and maturation are not yet complete, homeostatic stability is relatively fragile, increasing the risk of overexertion and the development of adaptive stress. This is particularly relevant for team sports, specifically futsal, which is characterized by high-intensity interval training, frequent changes in pace, and significant psycho-emotional stress. The aim of the study was to assess the level of adaptive stress in 15- to 16-year-old female futsal players based on immunohaematological parameters of peripheral blood. A group of athletes who train regularly and a control group of otherwise healthy peers without regular athletic training were examined. We determined the total white blood cell count and the white blood cell differential using the Romanovsky-Giemsa method, and calculated the integral adaptation index. Statistical significance was assessed using Student’s t-test. No statistically significant differences were found in total white blood cell count or red blood cell parameters between the groups. Female athletes showed an increase in the proportion of band neutrophils without the devel opment of leukocytosis, indicating mobilization of the bone marrow reserve and training-induced activation of the immune system. The values of the adaptation index corresponded to control indicators, with a state of calm activa tion - characteristic of physiological adaptation - predominating. Regular futsal training during adolescence contributes to the formation of an adequate adaptive response in the body without signs of chronic adaptive stress, confirming the safety of rationally dosed physical activity.
