Modern training and competitive load of qualified athletes make significant demands on the energy supply system and functions regulation. The functional state of the autonomic nervous system plays a key role in sport activity. Depending on the nature of the regulation mechanisms, the level of physiological reserves and the physiological adaptation price of the main adaptive systems, we determined the stability of the athlete's body to the training and competitive load. The purpose of the study was to determine the effectiveness of using means of correction of the functional state of the autonomic nervous system of qualified basketball players. Material and methods. We examined 18 qualified basketball players, the average age was 18.28±1.76. The study was conducted in compliance with World Medical Association Declaration of Helsinki – Ethical Principles for Medical Research Involving Human Subjects and approved by the Ethics Committee of the Ministry of Education of Baghdad. We obtained a written consent from all the participants before investigation. The program of remedial measures included the means of yoga therapy, autogenic training, regulated breathing exercises, taking into account violations of vegetative regulation, differentiated sports massage. Results and discussion. After the application of the course of correctional measures in the COs, there was a significant decrease in the stress index by 121.53 cu (p <0.01), as well as the index of vegetative regulation – by 125.14 cu (p <0.001); in the GP the decrease of the above-mentioned indicators occurred only by 33.40 (p> 0.05) and 33.76 cu (p> 0,05), respectively, indicating a decrease in the degree of centralization of rhythm management and activity of the sympathetic department of the autonomic nervous system. We noted that differentiated application of yoga therapy, respiratory exercises, autogenous training contributed to the intensification of parasympathetic and baroreflex effects on the cardiovascular system, reducing the tension of vegetative regulation, activation of compensatory mechanisms of long-term adaptation in athletes. At the end of the forming experiment we observed significant differences between the groups in almost all parameters of heart rate variability (p<0.05-0.01), except for the vegetative index and the index of activity ratio of the sympathetic and parasympathetic units. Conclusions: The study showed that the developed program of remedial measures for qualified basketball players helped to increase the tolerance of the autonomic nervous system to various stress factors, as well as to enhance the compensatory and adaptive mechanisms of long-term adaptation.
