[Effects of the beta-stimulating training in recovery of adaptive reserves in athletes of different sports]. / Effekty beta-stimuliruyushchego treninga v vosstanovlenii adaptatsionnykh rezervov u sportsmenov s raznoi napravlennost'yu trenirovochnogo protsessa.

Application of the beta rhythm neurofeedback is mainly dealt with when considering issues related to improving attention for clinical or preventive purposes. Cognitive and autonomic interactions formed with the help of biofeedback training, changing the function of autonomic and visceral systems, qualitatively improve the efficiency of any activity, including athletic activity, the nature of which is predetermined by the type of sports. OBJECTIVE: To identify effects of the beta-stimulating training in recovery of adaptive reserves in athletes of different sports. MATERIAL AND METHODS: The study included young male athletes aged 18-22 years (n=1020), distributed according to the type of sports: group 1 - cyclic sports (n=387); group 2 - speed-strength sports (n=255); group 3 - single combat (n=31); group 4 - team sports (n=173); group 5 - complex-coordination sports (n=174). The main objective of the beta-stimulating training was to select a strategy to raise the beta rhythm level while muscles were relaxed. For each group, we identified training efficiency periods according to the lowest value of the attention index (θ/ß, c.u.), then we examined distribution of brain rhythms (α, %; ß, %; θ, %) according to EEG. The level of adaptive reserves was identified according to the heart rate variability (HRV) spectral analysis («VNS-Spektr¼, Neurosoft, Ivanovo). RESULTS: We identified following periods of the beta-stimulating training efficiency according to the attention index (θ/ß, c.u.): group 1 - 10th session (game variant); group 2 - 5th session (graphic and game variants); group 3 - 1st and 10th sessions (game variant), 5th session (graphic variant); group 4 (game variant) - 1st, 5th and 10th sessions; group 5 (game variant) - 5th and 10th sessions. The efficiency periods in the observed groups were accompanied by the following distribution of rhythms in the EEG structure: ß-rhythm - 45-60%; θ-rhythm - 20-35%, α-rhythm - 19-25%. During these periods, wave structure of the heart rhythm also changed: the activity of VLF waves increased (%); the proportion of HF waves decreased in the range of 23.3-31.59% in the groups 1, 2 and 3; the share of HF waves increased in the range of 32.3-39.8% in the group 4 at the 1st session and in the group 5 at the 10th session. The values of total power (TP, ms2) reduce at the 10th session in the groups 1, 3 and 4 and at the 5th session in the group 5. The vagosympathetic balance coefficient (LF/HF, c.u.) in the studied groups corresponds to the range of normal values; the values increased in the group 2 at the 5th session, in the groups 3 and 4 - at the 5th and 10th sessions, in the 5th group - at the 5th session. The index decreased in the groups 3 and 4 at the 1st session. The index was stable in the groups 1 and 5 at the 10th session of the training. CONCLUSION: Periods of the beta-stimulating training efficiency associated with the improvement of attention according to the lowest values of θ/ß (c.u.) are accompanied by changes in the modulation of the structure of brain rhythms and the wave structure of heart rate variability, optimizing the psychophysiological state of athletes depending on the type of sport, the number of sessions completed and the session variants chosen.

[Natural healing factors of Nalchik resort in medical rehabilitation of the patients with post-traumatic stress disorder. (Randomized controlled trial)]. / Prirodnye lechebnye faktory kurorta «Nal'chik¼ v meditsinskoi reabilitatsii patsientov s posttravmaticheskim stressovym rasstroistvom. (Randomizirovannoe kontroliruemoe issledovanie).

INTRODUCTION: In order to optimize rehabilitation measures for post-traumatic stress disorder (PTSD) it is advisable to use natural therapeutic factors in the medical rehabilitation programmes of this category of patients, which is due to the pronounced psycho-corrective effects of climatic landscape therapy and nitrogen-thermal waters. AIM: To study psycho-corrective effects of a new rehabilitation technique for the patients suffering from PTSD using natural therapeutic factors of Nalchik resort. MATERIAL AND METHODS: Thera has been carried out a randomized controlled trial that included 74 patients with PTSD. Two groups were formed by simple randomization: in the control group (CG/n=38) the patients had standardized pharmacotherapy, physical training and individual psychocorrection in accordance with federal clinical recommendations; in the main group (MG/n=36) terrencourt in the natural park of Nalchik resort and nitrogen-thermal baths were additionally prescribed. The effectiveness of rehabilitation measures was monitored using a questionnaire to assess the therapeutic dynamics of PTSD, the Beck Hopelessness scale, as well as the Neurotech Kolibri wireless BFB complex (Russia). RESULTS: A comparative analysis of monitoring of psycho-emotional status indicators proved the feasibility of the developed medical rehabilitation programme for PTSD patients. A significant improvement in psychoemotional status was observed according to the questionnaire for assessing the therapeutic dynamics of PTSD (on average by 2 times, p<0.01), according to the Beck hopelessness scale, according to which the clinically assessed suicidal risk and hopelessness level were reduced by 1.7 (p<0.01) times with the patients in the MG. According to the analysis of brain biopotentials during the primary training, the patients had insufficient control over the course of mental activity (63%), and at the end of the course the indicator improved to 97% (p<0.01). In the CG positive dynamics on both scales of psychological testing and analysis of brain biopotentials was significantly lower (by 12-15%, p<0.05-p<0.01). CONCLUSION: After including in the standardized rehabilitation programme controlled walking in the mid-mountain Natural Park and nitrogen-thermal baths of Nalchik resort, there was a significant improvement in the psycho-emotional status of the patients suffering from PTSD, which indicates their psychocorrective effects and provides great opportunities to improve the effectiveness of medical rehabilitation.

[Natural therapeutic factors in medical rehabilitation of patients with post-COVID syndrome]. / Prirodnye lechebnye faktory v meditsinskoi reabilitatsii patsientov s postkovidnym sindromom.

The feasibility of using therapeutic physical factors in post-COVID syndrome is due to their sanogenetic effects that ensure the restoration of impaired bodily functions, which serves as the basis for their use at various stages of medical rehabilitation of this category of patients. OBJECTIVE: To develop a new medical technology for the 3rd outpatient stage of medical rehabilitation of the patients with post-COVID syndrome using natural therapeutic factors of Nalchik resort. MATERIAL AND METHODS: There has been carried out a controlled study in compliance with the principles of randomization to develop an outpatient medical rehabilitation program including 168 patients with post-COVID syndrome. All the patients were divided into four groups: the control group (n=40) was prescribed pharmacotherapy and physical therapy in the hall in accordance with federal clinical recommendations; comparison group 1 (n=43) had drinking mineral water in addition; comparison group 2 (n=43) received physical therapy on the route of Nalchik resort terrainkur in addition to the treatment in comparison group 1; the main group (n=42) included a group psychotherapy on the Terrainkur route in addition to the treatment in comparison group 2. RESULTS: The results of the comparative analysis showed the feasibility of the developed outpatient medical rehabilitation program for the patients suffering from post-COVID syndrome: the overall effectiveness of rehabilitation measures increased compared to other follow-up groups by 10-15% due to the improvement of external breathing function (p<0.05), cognitive status (p<0.01), increased exercise tolerance (p<0.01), physical recovery (p<0.01) and mental health (p<0.01). CONCLUSION: The summation and integration of sanogenetic effects of physical factors, psychocorrective techniques, and pharmacotherapy provide a significant improvement in the physical and mental status of the patients with post-COVID syndrome.

[NATURAL THERAPEUTIC FACTORS IN MEDICAL REHABILITATION OF PATIENTS WITH POST-COVID-19 AT OUTPATIENT TREATMENT STAGE].

The purpose of the research is to study therapeutic efficiency of medical rehabilitation of patients with Post-COVID-19 syndrome at outpatient treatment stage including natural therapeutic factors and phyto products in rehabilitation programme. In Nalchik resort 64 patients suffering from corona virus disease COVID-19 have been examined. They were distributed into 2 groups. 30 patients of the group of comparison were prescribed mineral water «Nalchik¼, exercise therapy, foam cocktails and rectal suppositories with thick licorice root extract. 34 patients of the main group additionally had natural aeroionophyto therapy along the route of mid-mountain natural park of Nalchik resort in combination with exercise therapy and group psychotherapy in park curative grounds and nitrogen thermal baths. The effectiveness was assessed with the help of the scale «Medical Research Council¼ (mMRC), the level of glycyrrhic acid in blood serum, functional tests, cardiointervalography in dynamics. The conducted comparative analysis proved the ability of natural therapeutic factors to influence the main life-supporting body systems positively. Therefore, the patients of the main group had a reduction of apnea by 29,4% (p<0,01) in comparison with the primary data, increase in adaptation capacity, on average, by 42,4% (p<0,01), improvement of physical activity, on average, by 36,2% (p<0,01), normalization of hemodynamic parameters. It was significantly better (by 20-25%, p<0,05) compared to the treatment in the group of comparison. There has been developed a new method of medical rehabilitation of patients with Post-COVID-19 syndrome at outpatient treatment stage including phytotherapy with licorice root extract and natural aeroionophyto therapy, exercise therapy, psychotherapy along the route of mid-mountain natural park in Nalchik resort, which significantly promotes (p<0,05) optimization of rehabilitation activities.
