Abstract
Recovery of athletes after strenuous muscular activity is one of the most up-to-date trends in current sports medicine. Therefore, neurobiofeedback technology, a complex of ideas for methods, based on biological feedback, is sufficiently promising. Available studies of neurobiofeedback by beta rhythm use in clinical medicine indicate a powerful therapeutic and rehabilitative potential of the method with pronounced correction of higher mental functions activity, volitional control and voluntary regulation of activity.
Objective: To examine the impact of one procedure of neurobiofeedback by beta rhythm of the brain on the cardiovascular system functional state in the athletes with different character of motor activity.
Material and methods: The study included 1020 male athletes aged 18-21 years. Depending on the motor activity, patients were divided into 5 groups: 1st group - cyclic sports athletes (38%); 2nd group - speed-power sports athletes (25%); 3rd group - combat sport athletes (3%); 4th group - team sports athletes (17%) and 5th group - athletes of complex coordination sports (17%). The procedure of neurobiofeedback by beta rhythm of the brain was done in the conditions of active waking at open eyes. Registration of bioelectric activity of the brain and training on beta rhythm were done in the Fz-Cz lead by the international system «10-20» with the arrangement of indifferent electrode on the earlobe of the subjects (PAC «BOSLAB», Institute of Molecular Biology and Biophysics, Novosibirsk, Russia).
Results: Heterochronic pattern of changes in the indicators of systemic pressure, cardiac and vascular activity of the athletes' body during a single procedure of neurobiofeedback by beta rhythm of the brain in the preparation period of the training process, depending on the character of athletic activities, was found. In response to the impact, the following indicators have changed significantly: heart rate and index of functional changes in combat sport athletes (3rd group); stroke and cardiac output in all groups. Cardiovascular regulation index and specific peripheral vascular resistance significantly increased in the groups 2-5. Cardiac index significantly decreased in the groups 1, 2, 4 and 5. Qualitative changes in types of blood circulation occurred in all groups: in groups 1, 3 and 5 - from hyperkinetic to eukinetic, in group 2 - from hyperkinetic to hypokinetic, in group 4 - from eukinetic to hypokinetic, contributing to the economization of cardiovascular activity function.
Conclusion: The use of neurobiofeedback by the beta rhythm of the brain in the practice of sports medicine requires additional detailed research of the features and development of individual methods depending on the type of athletic activity, features of cardiac activity regulation, etc.
期刊介绍：
The journal deals with the study of the mechanism of a physiological and therapeutic effect of physical and health resort factors, methods and results of their employment, as well as with theoretical and practical problems involved in the use of exercise therapy in combined treatment of different diseases. The results of research and experience of using physical and health resort methods in medical practice and organization of physiotherapeutic and sanatorial and health resort service, book reviews on physiotherapy, health resort science and exercise therapy are published. Scientific life of allied specialities, proceedings of congresses, conferences, symposia (including foreign), the activity of republican and local societies, etc., are covered.
