Aim. To determine the effectiveness of hardware and software complexes in assessing the psychophysiological state of persons in extreme conditions professions. Material and methods. The post-hoc comparative analysis of sensitivity, specificity, and overall accuracy of five hardware and software complexes was performed involving 459 patients of different medical and preventive care institutions that received the rehabilitation medical care. The simulation of altered reactivity in 6 athletes of cyclic kinds of sport was carried out within a daily experiment (5 men, mean age 21.1±0.7 years and one woman, 22 years; sport rank not lower than 1 senior degree). Psychophysiological testing was conducted at five time points using the following methods: hardware and software complex “Diamed-MBS”, ASD (Radix), Lusher colorchoice test (Radix), reaction to a moving object (Multipsychometer), static and dynamic tremorometry (Multipsychometer). Results and discussion. The diagnostic effectiveness of these psychophysiological examination data automated processing complexes were determined by their informative value, the ability to recognize signs of the disease with a so-called reference or benchmark diagnosis. The highest indicators of sensitivity (82.5%), specificity (79.3%) and overall accuracy (80.6%) were found in the Diamed-MBS hardware and software complex. A tendency to decrease in the main indicators, such as heart rate, stress index, activity, well-being, working capacity with a minimum at 3:00-5:00 hours, was revealed. During the day, the possibility of the athletes’ psycho-emotionalstate dynamic assessment during the day (somatic and psychological components) was evaluated according to the parameters of heart rate variability, electrosomatography and bioelectrography. The dynamics of psychological and psychophysiological diagnostics indicators was of the multidirectional nature, which does not allow us to assert unequivocally about the negative impact of daily rhythms on the condition of athletes. All athletes showed negative results in one way or another at different intermediate diagnostic points, but by the end of the study they managed to compensate and reach the results of the primary diagnosis. Conclusion. The diagnostic efficiency of complex screening diagnostics when using hardware and software complex “Diamed-MBS” is 80.6%, which is 25-35% higher than the same parameter for similar devices. No negative psychological and psychophysiological effects of stress stimulation on daily rhythms of athletes were defined.

An urgent task today is the formation of scientific approaches to the creation of a system to assess the effectiveness of medical technologies in sports medicine, taking into account the increased requirements not only in assessing their safety, but also with the mandatory analysis of their impact on the parameters of functional readiness of the athlete. We conducted the study using a comprehensive methodological approach developed in terms of the possibility of its application in case of mono-factorial exposure (means of pharmacological support). Aim. To determine the effectiveness of pharmacological agent’s complexes indicated for use in the prevention of fatigue by their effect on physical performance and psycho-emotional state of persons professionally engaged in sports. Material and methods. We performed a retrospective analysis of 30 athletes involved in skiing sports (biathlon, cross-country skiing and cross-country skiing) and evaluated the efficacy of two combinations of pharmacological agents not included in the WADA banned list, indicated for the prevention of fatigue, compared with placebo. Functional state of the athletes was estimated on the 7th and 15th days according to the parameters of endurance testing on the “Norwegian” protocol “until failure”, 5 loading steps, psychoemotional state (hardware-software complex “Diamed-MBS”, psychological status (Lusher test, WAM, Mini-Mult) on the 7th and 15th days. We analyzed the dynamics of general and biochemical blood tests, general urinalysis. Results and discussion. Load time before failure, the main indicator characterizing the success of the athlete’s professional activity, did not differ in all three groups when testing the background values, on the 7th and 15th days of the study, but consistently increased from the beginning to the end of the experiment. On the 15th day, 15 the time of specific load “to failure” in all three groups differed from the corresponding background values (p <0.05) due to the training effect. Application of the evaluated drugs had no effect on the level of IPC index in all three groups, but it tended to increase by the end of the experiment due to the trained athletes. The use of the drugs had no effect on the psycho-emotional and psychological state in all groups under study and at all testing points. Conclusion. Evaluation of the sports medicine technologies effectiveness should be carried out taking into account the requirements for their impact on the functional readiness of athletes, determining the success of professional activity. The studies have revealed no influence of the course application of the schemes of pharmacological agents of GCS and GCM against the background of the standard training program and periodic submaximal physical activity on the functional capabilities of the athletes’ organisms. The possibility of using the developed methodological approach to evaluate the effectiveness of sports medicine technologies based on monofactorial effects is shown, using the example of approved pharmacological agents indicated for reducing fatigue.
BACKGROUND: In the context of the COVID-19 pandemic, the relevance of rehabilitation measures for patients with COVID-associated pneumonia has increased. AIM: The study aimed to review the effect of bioacoustic stimulation of the respiratory system (BSRS) with high-intensity low-frequency sounds on the dynamics of functional indicators of the respiratory system and the cardiovascular system, as well as indicators of psychoemotional and somatic states, the severity of post-traumatic stress disorders (PTSD) and cognitive capabilities in patients who have had COVID-associated pneumonia in the process of their medical rehabilitation at a health resort immediately after treatment of the disease in a hospital. MATERIALS AND METHODS: The randomized controlled open parallel prospective clinical study involved 28 patients undergoing medical rehabilitation after suffering moderate to severe COVID-19 complicated by community-acquired bilateral polysegmental pneumonia (COVID-associated pneumonia) of moderate to severe severity. Spirometry, pulse oximetry, compression oscillometry, bioelectrography, Mississippi Scale (civil version), and cognitive speed test were used to assess the functional parameters of the respiratory and cardiovascular systems, as well as indicators of psychoemotional and somatic states, the intensity of PTSD and cognitive abilities of patients before and after the course of rehabilitation measures. RESULTS: According to significant differences in changes in the indexes of external respiration, cardiac activity, psychological status, and the intensity of PTSD in patients of the main and control groups before and after a course of rehabilitation measures, it has been reliably established that the use of BSRS as a part of a complex of rehabilitation measures significantly increases the effectiveness of medical rehabilitation at a health resort for patients after COVID-associated pneumonia. CONCLUSION: The possibility and feasibility of using medical technology of BSRS with high-intensity low-frequency sound in complex medical rehabilitation of patients after COVID-associated pneumonia at the health resort stage have been scientifically substantiated.
