Abstract. Introduction. High neuro-emotional stress among medical workers in organizations with the leading harmfulness of Covid-19 contributes to the formation of an unfavorable functional state, increases the risks of health disorders. The study of the characteristics of the psychophysiological reactions of the body will allow to substantiate the timing of work in a pandemic, which is quite relevant at the present time. The purpose of the research was, on the basis of comprehensive psychophysiological studies, to study the features of the formation of a functional state in medical personnel working in organizations with COVID-19 under the influence of stress factors of the labor process. Materials and methods. A physiological and hygienic assessment of the intensity of the labor process was carried out, psychophysiological changes were studied during 3 months of work in the «dangerous» zone. Statistical processing of the obtained data was carried out using the statistical programs Statistika 10, Microsoft Excel 2010. Results. The formation of neuropsychic stress in medical workers is reflected in changes in ECG indicators (prolongation of the QT interval, decrease in the voltage of the P and T waves) and systemic arterial pressure, an increase in the endurance coefficient (an indicator of detraining of the cardiovascular system), positive values of the Kerdo autonomic index (predominance of sympathetic influences) after 3 months of work in medical organizations with Covid-19. Conclusions. Nervous and emotional tension at work is the leading professional factor among nurses and doctors working in medical institutions with Covid-19 (hazard class 3, grade 3). Indicators of the cardiovascular system, reflecting the degree of adaptation of the body of medical workers to production activities, can be used to justify different periods of work in organizations with Covid-19.

Abstract. Introduction. The relevance of the research topic is due to the need to develop and scientifically substantiate physiological criteria for assessing working conditions in difficult cases according to indicators of the functional state of the body (in accordance with the section "General hygienic assessment of working conditions" of Guideline R 2.2.2006-05). The aim of the work is to determine changes in the functional state of the body in workers of mental, visual-intense, physical activity on the basis of complex physiological and hygienic studies to substantiate quantitative physiological criteria for different classes of labor intensity. Materials and methods. Complex industrial physiological and hygienic studies included an assessment of the degree of labor intensity with the analysis of retrospective data, physiological studies of the central nervous system, visual analyzer, neuromuscular apparatus, cardiovascular system of mental workers (52 groups), visually stressful (32), physical labor ( 71 professional group). Statistical processing of the obtained data was carried out using the statistical software Statistika 10, Microsoft Excel 2010. Research results. It is shown that the depth and time of the onset of physiological changes depend on the degree of labor intensity, which makes it possible to calculate the percentage of decrease in functions, taking into account the intensity class of the labor process. The list of physiological criteria for confirming the class of working conditions is determined by the characteristics of labor activity, with mental work these are indicators of concentration of attention and the volume of working memory, with visually intense labor, the critical frequency of fusion of light flashes, with physical labor, muscle endurance and heart rate. Conclusions. Quantitative physiological criteria have been established for various types of labor activity, which provide a valid evidence-based assessment of the class of working conditions according to the characteristics of the intensity of the labor process and control of the levels of the functional state.

The article provides the results of determining the level of physical development of the 1th-2nd course students of design specialties of the College of Construction, Architecture and Design. The physical development of students was determined by indicators of harmony of the bodybuilding (Kettle index 2), functional state of the cardiovascular system (Ruffier index), and respiratory system (Stange test). Length and weight of the body, heart rate, breathing delay time were measured. As a result of the researches, the “average” level of the physical development is determined in the 1th-2nd course girls and “sufficient” - in boys. Thus, mass-growth indicators of students according to the calculation of Kettle 2 index, both boys and girls correspond to the assessment of 5 points, which indicates a harmonious physique of students; indicators of the functioning of the cardiovascular system (Ruffier Index) of 1st year boys and the 2nd year students make 2 points, which corresponds to the ”below average” level, and the results of the 1st year girls equal to the assessment of 3 points, “average” level; indicators of the functional state of the respiratory system (Stange test) of boys of the 1th-2nd  course correspond to the assessment of 4 points (“above the average” level), and girls of both courses - 3 points (“average” level). In the age and gender aspects, physical development indicators, in general, don’t significantly differ with the general tendency to increase results with age and the dominance of boys over such in girls. The exception is the Ruffier index, where there is an opposite trend - the results decrease with age in girls and they are higher than in boys. Thus, the results of the research indicate the feasibility of introducing the 1th-2nd course students of professional pre-high education of special physical exercises into the process of physical education to improve the functional state of the cardiovascular and respiratory systems.

Introduction. Maintaining and strengthening young athletes’ health is very important since a growing body is more sensitive than an adult one. The overload on young athletes’ bodies’ functional systems is much higher compared to their peers who do not engage in intense physical activities and sports. This study aimed to assess the functional changes in the body of young athletes practicing sports games in the training process. Materials and methods. The functional state of the body of young athletes practicing five types of sports (volleyball, basketball, football, tennis, and handball) was studied on a representative group of 94 people, of which 50 (53.2%) males and 44 (46.8%) females with an average age of 17.7 ± 0.19 years. The cardiovascular system, central nervous system, respiratory system, and musculoskeletal system were investigated. The functional state assessment was carried out, taking into account the degree and direction of changes in the dynamics of training of individual indicators and integral indicators. It was determined the degree of risk of developing adverse functional changes. To identify premorbid states, we establish the type of self-regulation of blood circulation. Results. The obtained results in this study indicate that significant changes express the biological significance of the response of athletes to the conditions of training in the indices of the functions of the cardiovascular and central nervous systems and the musculoskeletal system. The indices of the functional state of the young athletes’ body at the end of the training changed in both directions. The degree of their severity fluctuated within limits from little too clearly expressed values. On the part of the cardiovascular system, an acceleration of heart rate from 60.1 ± 0.93 to 123.1 ± 0.93 beats/min (p < 0.001) was noted, an increase of systolic blood pressure from 101.1 ± 2.84 to 129.2 ± 1.40 mm Hg. (p <0.001), diastolic arterial pressure from 65.8 ± 1.60 to 76.3 ± 1.20 mm Hg. (p < 0.001), pulse pressure from 33.5 ± 2.35 to 71.5 ± 0.85 mm Hg. (p < 0.001), systolic pressure from 78.3 ± 1.75 to 84.2 ± 1.06 ml (p < 0.001), minutes volume from 4.3 ± 0.22 to 10.3 ± 0.11 l (p < 0.001), total peripheral resistance from 934.2 ± 42.11 to 1646.4 ± 37.61 dyn•s/cm5 (p < 0.001). On the part of the central nervous system, there was an increase in visual motor reaction from 236 ± 20.0 to 389 ± 5.3 ms (p < 0.001) and the auditory-motor reaction from 160 ± 3.8 to 256 ± 7.7 ms (p < 0.001). Young athletes who play volleyball have a higher load on the cardiovascular system. Functional changes are more pronounced in female athletes. The risk of developing unfavorable functional changes was noted for 15 physiological indices. The relative risk varied within 1.03-2.45 for boys and 1.04-2.90 for girls. The most pronounced risk is characteristic for total peripheral resistance (RR = 1.60), minutes volume (RR = 1.58), systolic pressure (RR = 1.55) in boys and systolic pressure (RR = 2.35), minutes volume (RR = 2.21), systolic arterial pressure (RR = 1.75), diastolic arterial pressure (RR = 1.73) and peripheral blood pressure (RR = 1.52) in girls. Conclusions. When playing sports games, a specific professional environment for different types of sports games is formed, this harming the functional state, performance, and health of young athletes.

The research goal is to increase the duration of the period of productive use of cows in modern complexes for milk production. The object of research is cows of the newly created intra-breed middle Volga type of black-and-white breed, culled for various reasons from the herd in the period from 2016 to 2018. All animals for further statistical processing of the studied indicators were divided into four groups, taking into account the type of stress resistance according to the method of E. p. Kokorina in the modification described by E. N. Letyagina. It was found that all hematological indicators decrease with increasing stress resistance in cows, except for the content of white blood cells. An increase in the concentration of white blood cells in the blood by 6.8-41.9% is probably a protective reaction of the body. Different reactivity of cows to the action of stress factors has an impact on the natural resistance of their body. A decrease in BASC by 3.2-10.5% was found, LASC – by 3.5-9.0%, FUNK-by 1.8-7.3%. When stress resistance decreases, the concentration of immunoglobulins in the blood decreases: IgG-by 3.9 – 11.2%, IgM-by 1.1 – 22.5%, IgA-by 3.4 – 24.1%. Studies have shown that cows of the first type of stress was superior to their peers with high stress-STU life expectancy at 262,6-1264,8 day (11,6-100%; P<0,05-0,001); in the long-STI period of productive use – on 0,2-2,5 lactation (4,7-125%; P<0.001); the magnitude of the average milk yield per lactation on 487-2175 kg of milk (8,5-53.6 percent; P<0,05-0,001); the value of lifetime milk yield – for 3340-19924 kg of milk (13.5-245.5%; P<0.01-0.001); for milk yield per 1 day of life-0.2-4.7 kg (1,8-73,4%; P<0,001), on the 1st day of lactation – 2,3-5,5 kg (13,9-41,4%; P<0,001). It is recommended that the" breeding core " of the herd be equipped with animals of types I and II of stress resistance. When using type II stress resistance cows, additional attention should be paid to the milk productivity of their mothers when selecting breeding bulls.

Personal protective equipment has become the last line of protection for medical personnel during the pandemic of the new coronavirus infection since it allows minimizing risks of biological contagion. Given the existing staffing shortage, medical workers have to spend from 4 to 12 hours a day in the “red zone” where they necessarily wear personal protective equipment. Protective clothing is known to produce negative effects on functional state of the body and personnel’s working capacities. Assessment of up-to-date protective suits will allow developing recommendations on their suitable application bearing in mind a balance between necessary protection, providing favorable ergonomics, and reducing risks of adverse effects on functional state and working capacities. Our research aim was to hygienically assess health risks for medical workers who had to wear reusable protective suits. Our research object was a reusable suit made from polyether fabric with polyurethane membrane coating and antistatic threads. We performed an experiment aimed at evaluating thermal state of the body, psychophysiological state, and responses by the volunteers’ cardiorespiratory system in laboratory conditions during an 80 hour working shift under controlled microclimate. Participants in the experiment were questioned in order to assess suits’ ergonomics. Heat exchange dynamics and amount of changes in thermal physiological parameters caused by wearing a protective suit determined heat contents of volunteers’ bodies that conformed to optimal standard values. Data on psychophysiological and mental state taken in research dynamics didn’t have any statistically significant changes. Gas exchange indicators naturally grew during the “load” phase; however, there were no significant changes detected in any phase in the research. Hygienic assessment of the thermal state, functional state of the cardiovascular and respiratory systems, and psychophysio-logical indicators confirmed that wearing a protective suit was quite safe and didn’t involve any health risks for volunteers.

Introduction. Laboratory practice is characterized by an increased hardness of the work process. In the research presented, a complex comparative assessment of the working conditions and functional condition of the employees of the laboratory center “Center for Hygiene and Epidemiology in the Voronezh Region” was carried out, in which a laboratory information system (LIS) is planned to be introduced into the practice. The assessment of the conditions of the labor process and the functional state of the employees was also carried out in the testing laboratory of the Center for Hygiene and Epidemiology in the Tambov Region, where the LIS software operates in the regular mode. Material and methods. The study was conducted on 170 specialists of testing laboratory centers. There are given data on the assessment of the hardness and intensity of the labor process of laboratories of different types of activity at workplaces of testing laboratory centers in the Voronezh and Tambov regions. There was performed a clinical examination of specialists of testing laboratory centers on the indications of the cardiovascular system: dynamics of the heart rate, systolic and diastolic blood pressure, minute blood volume during the working day. Results. Based on a comparative analysis of the results obtained, conclusions were drawn about the peculiarities of working conditions and performance indices of employees of testing laboratory centers in the dynamics of the working week. Differences in the formation of fatigue in the specialists of laboratories for hygienic and epidemiological profiles of activity among employees of a testing laboratory center, working without an information system introduced into the professional activity, have been observed in the second half of the working day, whereas those working with a laboratory information system the state of the body is correct from the physiological positions. Discussion. The class of labor conditions for specialists in testing laboratory centers, regardless of the profile of activity according to the severity of the work process, was identified as hard work of grade 1 (3.1), the class of working conditions for the intensity of the labor process as a hard work of grade 2 (3.2). Evaluation of the functional state of the body according to the cardiovascular system testifies to a noticeable fatigue in the second half of the working day among specialists working without software and information support. Conclusions. The data obtained as a result of the research made it possible to develop and offer a complex of preventive measures aimed at optimizing working conditions for the introduction into the professional work of personnel of testing laboratory centers. As a result, additions were made to the Instruction on labor protection of specialists of the Center for Hygiene and Epidemiology in the Voronezh Region.

Introduction.Much attention is paid to the analysis of problems that arise during the initial stage of children's education in school in recent years. Preschool age is one of the sensitive and critical stages of individual development. Explicit structural and functional changes occur during this period. These changes are accompanied by an increase in the functional stress of psychovegetative mechanisms of regulation. Both psychological and physical stress are considered to be the cause of autonomic disorders. Such a provoking factor may be the beginning of school for a child. Formation of visual and auditory perception is one of the leading functions of cognitivedevelopment for older preschool children. This function provides the child's interaction with the external environment and its orientation in space. This function is also an indicator of the child's readiness for school.Therefore, the importance of studying the features of the functional state of the cardiovascular system during the audio-visual load of educational and developmental nature is relevant.Thepurposewas to study the features of autonomic regulation of heart rhythm of children 5-6 years old under conditions of cognitive load.Methods.Observation was carried out on children 5-6 years of age of preparatory groups of preschool educational institutions of the Sumy city (n = 192). We assume that changes in autonomic functions may be influenced bythe immaturity of motor-motor, visual-auditory, speech-auditory and visual-graphic components. An important component of educational and cognitive activities in preschool age is the development of reading and writing. Visual information was studied from two positions pictorial (elements of writing) and verbal (recognition of letters and words elements of reading).The method of phasography was used to study the state of the cardiovascular system. This method was used using the device "Phazagraph". This device is designed for recording and analysis of the electrocardiogram in the phase space to estimate the amplitude and speed parameters of any elements of the electrocardiogram, which allows you to accurately estimate the graph of the electrocardiogram.Results.It was found that sympathicotonia is manifested among the examined children aged 5 and 6 years during cognitive load. Activation of the sympathetic part of the autonomic nervous system occurs during writing compared to reading. That is, the adaptive mechanisms of the autonomic nervous system correspond to lower rates during writing compared to reading. The reason for this may be the immaturity of autonomous supply systems and mechanisms for their regulation and indicate an imbalance of autonomicsupply. In turn, the dominance of sympathetic influence on heart rate is accompanied by signs of dysregulation of cardiovascular functions during writing for children. The reason may be the immaturity of the functional systems of the interconnected brain areas, which is accompanied by a deterioration in the coordination of autonomic functions of the body. Originality. The idea of the formation of psychophysiological features in ontogenesis is expanded.Conclusion. A comprehensive assessment of children's adaptation to exercise was justified.
