BACKGROUND: Physical overload results in the development of pathological changes in the organs and systems and thereby causes their dysfunction. This leads to disadaptation, vegetative imbalance, and disturbances in the cardiovascular, nervous, endocrine and other systems. Taken together, these changes give rise to a syndrome of overtraining. In this context, the pathogenetically sound method of therapy appears to be the most suitable for the management of this condition based on the physiotherapeutic non-invasive interventions for the correction of physiological characteristics and the psycho-emotional status of the patients. One such method is bioresonance therapy (BRT). AIM: The objective of the present study was to evaluate the influence of bioresonance therapy (BRT) on the health status of the athletes presenting with the overtraining syndrome. MATERIAL AND METHODS: The study included 60 athletes presenting with the overtraining syndrome. They were divided into two groups each comprised of 30 subjects of comparable age, sex, sport, and sports qualification. Group I was composed of 30 athletes who were treated by means of bioresonance therapy. Group II (control) contained the athletes who received placebo procedures (i.e. the procedures with the use of a non-functioning device). All the athletes were examined before and after the treatment with the application of the clinical and instrumental methods. RESULTS: The study has demonstrated that the use of bioresonance therapy significantly increases the parasympathetic influence on the rhythm of the heart, reduces the stress on the central contour of its regulation, contributes to the 'economization' of the cardiac activity; has an antihypertensive effect (more pronounced with respect to systolic blood pressure (SBP)), has a normalizing effect on the variability of blood pressure (BP) in the patients with initial BP instability, and significantly decreases the time index in connection with monitoring blood pressure; moreover, BRT has a normalizing effect on the circadian rhythm of BP and corrects the rate of the morning rise in diastolic blood pressure (DBP). CONCLUSION: Bioresonance therapy can be considered as a method for the correction of the syndrome of overtraining in the athletes with the enhanced activity of the sympathetic nervous system.

Specialized sports nutrition is one of the most important factors in the extension of the functional potential of athletes, providing adaptive resistance to physical stress, which determines the high physical performance and prolongs athletic longevity of the athletes. The study involved 30 skiers-racers (the average age of 19.5±1.8 years). 12 skiers of the main group within 21 days consumed a specialized food product, obtained on the basis of fermented milk whey containing amino acids, several vitamins, minerals and trace elements, live culture of lactic acid bacteria: L. lactis, L. thermophilus, L. bulgaricus (1.2 × 10s CFU/cm3). The control group consisted of 18 skiers, those taking the placebo (food starch of the same consistency). After a course of product intake, blood level of hemoglobin increased by 6%, of leukocytes - by 10% due to an increase in the number of granulocytes by 32%, and segmented neutrophils by 16% (p<0.05), there was a tendency to increase the number of red blood cells by 7% with a significant decrease in lymphocyte count by 19%. Erythrocyte sedimentation rate in blood of the skiers from the comparison group increased by 41% (p<0.05), while in the athletes of the main group it decreased by 16% (p>0.05). After product intake it has been established by the method of laser Dopplerflowmetry that there was a tendency to increase blood perfusion by 15%, a statistically reliable increase in the flux by 53%, which is based on the improvement of the internal mechanisms of microcirculation regulation. According to the mathematical analysis of cardiac rhythm, centralization of regulation decreased while the activity of an autonomous mechanism for controlling the work of the heart increased. The revealed functional changes ensured an increase of absolute (by 31%, p<0.05) and relative (by 33%, p<0.05) physical performance and aerobic endurance of skiers, contributed to the improvement of short-Term memory. The conclusion is made about the expediency of the intake of the specialized food product to enhance the adaptive capacity of athletes under the influence of systematic physical loads.
