Modern youth sport, particularly futsal, is characterized by high intensity of physical and psycho- emotional loads, which significantly affect the functional state of the immune system in young athletes. During adolescence, the immune system is labile and highly sensitive to external influences, while genetically determined characteristics, including the ABO blood group system, may define the specificity of adaptive responses of the organism. Insufficient investigation of this issue in young athletes determines the relevance of the present study. Aim of the Study. To determine the characteristics of cellular, nonspecific, and immunological resistance of the organism in young futsal players aged 13–16 years depending on the AB0 blood group. Object and Research Methods. The study involved 57 young athletes who systematically practice futsal. AB0 blood groups were determined using standard methods. Cellular, nonspecific, and immunological resistance was assessed based on peripheral blood analysis with the calculation of integral hematological and leukocyte indices reflecting the functional state and adaptive capacity of the organism. Statistical processing of the results was performed using methods of variation statistics. Research Results and Their Discussion. Significant differences in the indicators of cellular, nonspecific, and immunological resistance depending on blood group were identified. The highest values of the cellular resistance index and immunological reactivity were observed in athletes with blood group B (III), indicating more pronounced adaptive capabilities to training loads. The maximum reactive response of neutrophil granulocytes was found in futsal players with blood group A (II). Nonspecific reactivity of the organism was highest in athletes with blood group O (I). Allergy-related indices remained low across all blood groups. Conclusions. The obtained results confirm the feasibility of considering the AB0 blood group as an additional factor in the individualization of sports training for young futsal players.
