The article presents the results of assessment and dynamic control over the functional state of military men in the midlands conditions. Depending on the initial type of autonomic regulation, groups with vagotonic (24%), sympatotonic (26%) and normotonic (50%) directions of regulatory processes were identified. It has been established that the state of optimal working voltage with more economical functioning of regulatory mechanisms is characteristic of carriages; for sympathotonics - an overstrain of regulatory mechanisms, and for normotonics - a moderate tension of regulatory systems with the mobilization of the functional reserves of the body. Key words: heart rate variability, functional state, types of autonomic regulation, midlands, military men.

In the last decade the health of young people inUkraineas well as in many other countries of the world significantly deteriorated according to the results of screening tests. Because of this the main task of prophylactic medicine is development and introduction of new methods of early diagnostics of diseases. The aim of the work to assess the peculiarities of adaptation of students with different types of vegetative regulation.Material and methods: 415 second year students ofLuganskStateMedicalUniversitywere tested. The mechanisms of physiological functions of the body regulation were assessed by registration of cardiac rhythm variability (CRV). Analysis of CRV was performed by three methods: statistical, geometrical, and spectral analysis. The express method proposed by Shlyk, N.I. (2009) was later used to determine the prevailing type of vegetative regulation. To assess adaptability the method of R.M. Baevskij (1979) was used.Results: In the result of investigation 4 types of functional states of regulatory systems were determined: I type – 295 (71 %) of tested, II – in 14 (3 %), III – in 96 (23 %) and IV – only in 10 (2%). I type of functional state of regulatory systems in the wakeful state at rest was characterized by moderate prevalence of central regulation of heart rhythm (MPCR), decreased activity of autonomic regulation. It was noticed that some of the parameters of CRV (like R-R, SDNN, RMSSD and pNN50) which characterize autonomic regulation, were statistically lowere (р≤0.01) compared to type III, and some (like AMo and SI) higher, in both female and male students. Summarized spectrum capacity and components of its wave structure (HF, LF, VLF) which characterize central regulation were statistically significantly lower (р≤0.01) for the I type of regulation compared to the III one which is characterized by moderate prevalence of autonomic regulation of the heart rhythm. In female students with type I autonomic regulation compared to male students such CRV parameters as R-R and AМo were statistically significantly lower (р≤0.05), while the parameters of total potency (TP) and high frequency waves (HF) were higher (р≤0.05), which could point to more centralized heart rhythm regulation in male compared to female. The evaluation of regulatory systems overstress allowed to determine the state of adaptation and risk of overstress or breakdown in students with different types of autonomic regulation.Conclusions: Thus, evaluation of adaptation state in students with different types of autonomic regulation allows to characterize the current functional state and uncover the risk of disease development.

The research was carried out on two independent experimental groups of boys and girls. The first was observed in traffic conditions, the second during the period of auto-simulator training. The HRV indices were determined: HR - heart rate, IN - index of tension of regulatory systems, AMo - amplitude of the mode, LF/HF - index of vagosympathetic interaction. A pronounced sympathetic reaction of more prepared cadets to the training load with the subsequent restoration of the studied characteristics was revealed. Key words: heart rate variability, autonomic regulation, vagosympathetic interaction, driver training, level of preparedness.

Abstract: Introduction. Increasing information loads can lead to the development of professional stress and work-related illnesses in knowledge workers. The development and implementation of modern methods of control and correction of the functional state of employees in the conditions of activity is relevant. The study aims – to explore the dynamics of the functional state of knowledge workers in the conditions of modeling the cognitive load on the computer and during the training on neurofeedback (NFB) based on the parameters of the electroencephalogram (EEG). Materials and methods. 17 researchers (4 men and 13 women aged 22-63 years (34.8±3.4), with an average work experience of 12.1±3.3 years) participated in the study on the basis of voluntary informed consent. Results. A significant increase in the index of the alpha rhythm was shown by 29.4% of the subjects. It was found that the total power of the spectrum of heart rate variability (HRV) is higher, the adaptive risk is lower in the group that successfully passed alpha training (p<0.05). According to the results of continuous personalized heart rate telemetry, the dynamics of the functional state (FS) during the examination was determined for each subject. Conclusion. A significant influence of the state of neurohumoral regulation systems and adaptive reserves of the body on the success of the biofeedback training was established, which is the basis for the development of methodological approaches to the correction of FS, taking into account individual optimal management strategies.

Sports of the highest achievements requires the fullest possible use of the psychophysical capabilities of an athlete, which requires a fundamentally different approach, compared to mass sports, in the preparation of athletes using modern scientific methods for diagnosing the functional state of the body (FSB). Conducting scientific research with the required quality needs the use of multivariate analysis of the obtained primary data characterizing the FSB. Analysis by individual factors or analysis of only the final result does not allow to identify weaknesses and assess the reserves of the athlete’s body. The indicated requirements for multivariate analysis are satisfied by the Algebraic Model of Constructive Logic Algorithm (AMCLA), which is used in healthcare. AMCLA as an analytical tool allows performing complex analytical calculations and building expert systems on its basis. The AMCLA is based on the logic of predicates, which fundamentally distinguishes this mathematical apparatus from neural networks. The use of AMCLA cannot be considered as an alternative to the use of others methods of multivariate analysis. The best is the result of the analysis, confirmed by fundamentally different methods. Comparative analytical calculations with neural network algorithms have shown coincidence in the fundamental components of the result. Nevertheless, AMCLA can also identify the most characteristic differences, evaluate restrictions in the choice of treatment and the correct choice of factors, which is important in analytical studies in biomedical research. To participate in the study, 182 qualified male athletes aged 19–22 years (20.5±1.5) were selected, with different levels of functional reserves. They were engaged in sports with a high dynamic and static component (football, basketball, volleyball, boxing, swimming, athletics), according to the classification by Mitchell JH and co-authors, who are at the stage of improving their sportsmanship. The dysfunctional orientation of regulatory mechanisms in qualified athletes in groups with rhythm disturbances and impaired repolarization processes against the background of a decrease in physical performance and stress of adaptation mechanisms was reliably classified by phasographic speed indicators of the heart electrical activity, which was determined using AMCLA. Innovation indicators averaged phase of the cardiac cycle suggests a lack of verified earlier values that characterize the different states. In this case, AMCLA made it possible to identify the most significant indicators of the phase averaged cardiac cycle to characterize various states and differentiate the ranges of their values. Multivariate analysis of the functional state indicators of the athlete’s body with the use of AMCLA can be a methodology for solving the problems of reserve measurement in the highest achievements sports.

The purpose of this research was to analyse the functional state of the central and autonomic nervous systems in young emergency physicians working in the northern region. Materials and methods. We examined 33 emergency physicians of a multidisciplinary hospital in Khanty-Mansi Autonomous Okrug – Yugra aged 25 to 43 years (19 men and 14 women). The functional state of the central nervous system (CNS) was assessed using the method of simple visual-motor reaction (SVMR) and criteria developed by T.D. Loskutova – system’s functional level (SFL), reaction stability (RS) and level of functional abilities (LFA) – as well as attention stability, working memory and Whipple’s accuracy index. The state of autonomic regulation was evaluated according to the dynamics of heart rate variability (HRV) at rest and during active orthostatic test (AOT). Results. We found that male emergency physicians have higher rates of psychomotor reactions, SFL, RS, and LFA than their female colleagues. SVMR showed pathological reactions of the CNS in subjects of both sexes. The body’s adaptive capabilities due to autonomic regulation were preserved in most emergency physicians. However, a pathological response to AOT was found in both men and women. The pathological basis for impaired autonomic regulation and the development of maladaptive reactions in the subjects was a deterioration of the current functional state of the body, excessive activation of the sympathoadrenal system and a decrease in parasympathetic regulation. Responses to AOT in male emergency physicians were accompanied by a decrease in the total power (TP) of the HRV spectrum by 24.7 %, and an increase in low frequency (LF) to high frequency (HF) ratio by a factor of 2.6; while in female doctors, by a decrease in TP by 11.5 % and an increase in LF/HF ratio by a factor of 1.7. The median of 30/15 coefficient was 1.48 for men and 1.45 for women. Thus, in the course of professional selection of doctors to provide emergency care under unfavourable climatic conditions of the North, it is advisable to conduct a comprehensive examination of the functional state of the central nervous system and autonomic regulation to identify a risk group with impaired adaptation mechanisms.

Relevance . Maintaining the health of migrants while adapting to the new climatic and geographical conditions of residence is an urgent task. The impact of non-specific factors on the body of migrants in new climatogeographic conditions leads to the strain of regulatory and adaptive mechanisms, and in extreme cases to their failure. Objective - to determine the features of heart rate variability in young Tajiks, depending on the type of temperament living in Krasnoyarsk for more than a year. Materials and Methods: A study of heart rate variability in 63 Tajiks aged 18-40 years with different types of temperament, living in Krasnoyarsk for more than a year, was conducted. The types of temperament were determined by indices in accordance with the method of identifying VP-types of temperament according to E.Yu. Petrosyan, Yu. I. Savchenkov. The following indicators of heart rate variability (HRV) were evaluated: heart rate, the power of the high-frequency, low-frequency and very low-frequency spectrum (BV, MV-2, MV-1) of the HRV component, the voltage index of regulatory systems (IN), the centralization index (CI) and the activity index of regulatory systems. To assess the statistical significance of the differences between the samples, the Students criteria were used. Results and Discussion. It was revealed that migrants with an intense type of temperament after moving to a new place of residence increased the indicators of heart rate, BV and IN. At the same time, in the studied groups with a calm and adequate type of temperament, the power of BV was significantly reduced, with an increase in heart rate and CI. The conclusion is made about the influence of typological features of temperament on HRV indicators, when adapting to new climatogeographic living conditions. Individuals with an adequate type of temperament demonstrate the normal functioning of the adaptive capabilities of the body. In individuals with the calm type, an increase in the tension of the regulatory mechanisms was revealed. Conclusion . Significant changes in HRV are demonstrated by migrants with an intense type of temperament, in particular, they are characterized by a high voltage of regulatory mechanisms.

According to the authors, the assessment of the functional state of the cardiorespiratory system of the body during physical training and sports is of paramount importance because of the huge role of this system in the adaptation to physical activity of different nature, the optimal functioning of the organism in the most varied in terms of training activity. The analysis of the scientific literature shows that the deterioration of the indicators of the functional state of the cardiorespiratory system of the human body caused by the weakening of socio-economic conditions in the country, the influence of radioactive radiation, the deterioration of the quality of nutrition, the decrease of motor activity, etc. There is also a general increase in the number of cardiovascular diseases, deterioration of the body's functional reserves, systemic impaired posture, the presence of various disorders of the musculoskeletal system, a decrease in the level of physical fitness, etc. All this happens against the background of the weakening of the functions of the cardio-respiratory and nervous systems of the body during training and during the exams, which negatively affects the formation of health of future specialists. Therefore, since there is a tendency to deteriorate the health of students, in particular, the condition of their cardio-respiratory system, the question of improving it through the use of physical education is very relevant.

THE LEVEL OF ORGANISM FUNCTIONING AS AN INDICATOR OF PREMORBID CONDITIONS (REVIEW)Marakushin D., Melnychenko O., Chernobay L., Vasylieva O., Isaieva I., Karmazina I., Hloba N., Dunaeva O., Goncharova A. The state of the organism is the consequences of interaction with the environment, that is, the result of adaptation or maladaptation of the organism to the environment. The transition from health to illness can be seen as a process of gradually reducing the ability of a person to adapt to changes in social, educational, and production environments and surrounding conditions. Achievement of any level of functioning of an organism or its separate systems is provided through the activity of regulatory mechanisms. The mobilization of reserves occurs as a result of changes in the level of activity of regulatory systems. First of all, this is due to an increase in the tone of the sympathetic department of the autonomic nervous system. In those cases where the body constantly has a deficit of functional reserves to support homeostasis, there is a state of functional stress, which is characterized by the displacement of the autonomic balance in favor of the adrenergic mechanisms and the corresponding changes in the hormonal state. In the state of functional stress, all of the basic functions of the body are within physiological norm, but the organism spends functional reserves to maintain the normal level of functioning. The process of adaptation precedes the development of a disease that results from the lack of adaptation mechanisms, their reduction and disruption. The development of maladaptation is preceded by the state of adaptability, and after the maladaptation the state of the disease develops, i.e. all the conditions that precede the disease, that is, the failure of adaptation, are united in the premorbid state. The process of identifying the states that border between the norm and the pathology, when it does not yet have signs of the disease, that is, the premorbid states, is called premorbid diagnostics. Diagnostics of the premorbid states takes into account the use of methods and equipment that are designed for processing information in the range of relative functional stability of the organism with the definition of the vector of adaptation processes and that is an integral part of preventive medicine.

Стан організму є наслідком взаємодії з навколишнім середовищем, тобто результатом адаптації або дезадаптації організму до навколишнього середовища. Перехід від здоров'я до хвороби може розглядатися як процес поступового зменшення здатності людини адаптуватися до змін у соціальному, освітньому та виробничому середовищі та навколишніх умовах. Досягнення будь-якого рівня функціонування організму або його окремих систем забезпечується через діяльність регуляторних механізмів. Мобілізація резервів відбувається внаслідок зміни рівня активності регуляторних систем. Перш за все це пов'язано зі збільшенням тонусу симпатичного відділу вегетативної нервової системи. У тих випадках, коли організм постійно має дефіцит функціональних резервів для підтримки гомеостазу, виникає стан функціонального стресу, який характеризується зміщенням вегетативного балансу на користь адренергічних механізмів і відповідних змін гормонального стану. У стані функціонального стресу всі основні функції організму перебувають у фізіологічній нормі, але організм витрачає функціональні резерви для підтримки нормального рівня функціонування. Процес адаптації передує розвитку хвороби, що виникає внаслідок порушення процесів адаптації. Розвиненню дезадаптації передує стан адаптивності, а після дезадаптації розвивається стан захворювання, тобто всі умови, що передують захворюванню, об'єднуються в преморбідному стані. Процес ідентифікації станів, що межують між нормою і патологією, коли він ще не має ознак захворювання, тобто преморбідних станів, називається преморбідною діагностикою. Діагностика преморбідних станів враховує використання методів і обладнання, призначених для обробки інформації в діапазоні відносної функціональної стійкості організму з визначенням вектора адаптаційних процесів, що є складовою частиною профілактичної медицини.

Состояние организма - это последствия взаимодействия с окружающей средой, то есть результат адаптации или дезадаптации организма к окружающей среде. Переход от здоровья к болезни можно рассматривать как процесс постепенного снижения способности человека адаптироваться к изменениям в социальной, образовательной и производственной среде, а также в окружающих условиях. Достижение любого уровня функционирования организма или его отдельных систем обеспечивается за счет действия регуляторных механизмов. Мобилизация резервов происходит в результате изменения уровня активности регуляторных систем. Прежде всего, это связано с повышением тонуса симпатического отдела вегетативной нервной системы. В тех случаях, когда организм постоянно испытывает дефицит функциональных резервов для поддержания гомеостаза, возникает состояние функционального стресса, которое характеризуется смещением вегетативного баланса в пользу адренергических механизмов и соответствующими изменениями гормонального состояния. В состоянии функционального стресса все основные функции организма находятся в пределах физиологической нормы, но организм тратит функциональные резервы для поддержания нормального уровня функционирования. Процесс адаптации предшествует развитию заболевания, которое возникает в результате отсутствия механизмов адаптации, их уменьшения и нарушения. Развитию дезадаптации предшествует состояние приспособляемости, и после дезадаптации развивается состояние заболевания, то есть все состояния, предшествующие заболеванию, объединяются в преморбидные состояния. Процесс выявления состояний, которые граничат между нормой и патологией, то есть преморбидных состояний, называется преморбидной диагностикой. Диагностика преморбидных состояний учитывает использование методов и оборудования, предназначенных для обработки информации в диапазоне относительной функциональной устойчивости организма с определением вектора адаптационных процессов и является неотъемлемой частью профилактической медицины. Ключевые слова: Преморбидные состояния, функциональное состояние организма, функциональные резервы организма, преморбидная диагностика, профилактическая медицина
