Objective: to evaluate the functional state of cardio, neuro-endocrine and central nervous systems of highly skilled sportsmen of endurance sports under specific load. Materials and methods: 20 highly skilled short-trackers took part in the research. Evaluation of the functional state of cardiorespiratory system was carried out using a load test on the ergospirometry system SCHILLER; hormone levels, blood biochemical parameters were measured by solid phase of the enzyme immunoassay analysis on the photometer of vertical scanning «StatFax 303 Plus» (Germany); energy metabolism in the central nervous system was appreciated by the method of neyroenergocharting.
Results: the parameters of the functional state of the cardiorespiratory system of highly skilled short-trackers were comparable to that in the short-trackers with degrees. Specific physical activity caused the increasing of energy processes in the central and frontal areas of the cortex, the increasing of ТТG, Т4, АКТG, cortisol, β-endorphin (p ≤ 0,05).
Conclusions: sport achievements in cyclic sports connect with the use of the integrated approach in the assessment of the functional state. Functional state of the cardio, neuro-endocrine and central nervous systems can be used as one of the parameters it the medical-biological control, besides the biochemical analysis of blood before and after the load can be conducted.
