STRESS REACTIVITY, RESERVE CAPACITIES, SCALES AND INDIVIDUAL FEATURES OF THE FUNCTIONAL SYSTEM IN ADOLESCENT ATHLETES

Abstract

Aim. The paper aims to justify the features of the elements of the functional system in adolescent athletes in the conditions of differentiated successful sports performance and health maintenance. Materials and methods. Judo athletes ages 16–19 (1^st sports category, Candidates for Master of Sport, Master of Sport) participated in the study. The following equipment was used: AMP non-invasive analyzer, AT 104-PC Schiller Cardiovit, Omega-MS digital analyzer, MBN force plate. Medium-weight molecular peptides were calculated by using the Lowry protein assay; relative content of molecular products of lipid peroxidation was assessed by the method of I. Volchegorsky; creatine kinase activity was measured by a unified method; erythrocyte glucose consumption was assessed by the Luteus method. Results. A model for controlling and regulating the movement and special functional systems in athletes of various age, weight and skills was proposed. Conclusion. The special functional system model reflects the relationships between its subsystems, as well as the growth rate for the results obtained due to health recovery and mass sports activities. The criteria for the integral ranking indicator were established.
