The microcirculatory system plays a key role in supporting the trophic function of the circulatory system. During adolescence, a period marked by ongoing morphofunctional maturation, the adaptation of microcirculatory param eters to physical exercise is of particular importance for the development of physical performance and is considered one of the critical factors in athletic success. Purpose is to determine the specific effects of dosed physical exercise (DPE) on blood microcirculation parameters in young males depending on age and level of physical fitness. The study involved 106 young males aged 18–21 years, including both trained athletes and untrained students. Laser Doppler flowmetry was used to assess the dynamics of vascular perfusion indicators: microcirculation parameter (MP), stan dard deviation (SD), coefficient of variation (Kv), microcirculatory efficiency index (MEI), active (ARM) and passive (PRM) regulatory mechanisms of blood flow. In untrained individuals with low baseline MP values, DPE resulted in increased perfusion activity and blood flow variability, indicating the activation of compensatory mechanisms. In contrast, in those with high initial MP values, signs of vascular maladaptation were observed in some cases. Trained participants demonstrated more stable and structured microcirculatory responses, with features of functional econ omization and more balanced and effective involvement of both active and passive regulatory mechanisms of he modynamics. The microcirculatory response to physical exercise in young males is significantly influenced by age-related and functional characteristics of the organism, supporting the need for an individualized approach to training.
