Purpose. Assessment of functional state of circulatory system in seafarers at different stages independent cruise.Materials and methods. Retrospective analysis of the results of the study of three groups of 180 seafarers on the third, fifth and sixth months of cruise was conducted. The obtained results were subjected to statistical processing according to the rules of variation statistics.Results and its discussion. Functional state of circulatory system in seafarers depends on the kind of military professional activity. Thus, among the staff officers, the number of prehypertensive states is increasing, and for the personnel of surface ships a slightly greater physical working capacity is noted in comparison with divers. At the same time, an increase in the temperature of the skin of the lower extremities was typical for divers, that is definitely important for the control and early prevention of overheating. At the same time, the most noticeable decrease in working capacity is observed in the command staff, while the indicator was quantitatively correlated with the results of daily monitoring of blood pressure and ECG. In addition, it was revealed that the process of adaptation of the body’s regulatory systems reaches its maximum by the end of the third month of cruise and is determined by an increase in endurance and a decrease in morbidity among seafarers.

The Relationship

A variety of factors influence the performance of schoolchildren. The main factors are psycho-emotional stress and systematic physical activity that requires a constant tension of body's regulatory systems aimed at mobilizing the functional body reserves. The analysis of blood pressure enables to estimate quantitative and qualitative changes in the regulation of the cardiovascular system. The combination of the Stroop test and the monitoring of the cardiovascular system make it possible to assess not only attention and cognitive function parameters, but the phases of the stress response of regulatory systems as well. The purpose of the study was to analyze the relationship between stress factor and the functional state of adolescent cardiovascular system. In the context of stress factor (Stroop test), the circulatory system of students gets activated, and its indicators vary differently among boys and girls. At rest, girls have the lowest performance of the circulatory system. Before the test, heart rates vary in boys and girls in different ways. In the course of our study, we have found out a direct relationship between heart rate, blood pressure before and after psycho-emotional load that testifies the predominance of the sympathoadrenal system activity. We have revealed the arterial hypertension is determined by physiological and social factors. Prevention of arterial hypertension in existing standards of schools requires reconsidering and improving of educational approaches, especially in terms of physical education.

Introduction. The increase in tension and complexity of the naval personnel work is naturally accompanied by an increase in the risk of formation of unacceptable functional states and a critical decrease in professional reliability. Timely detection and prevention of such states is impossible without the implementation of dynamic monitoring of naval personnel working capacity in the process of professional activity. Purpose of research — substantiation of complex technology of functional state and working capacity control of naval personnel. Materials and methods. During performance of work 215 ship experts of various profile of activity were examined. The studies were carried out using an automated functional state screening control system designed on a modular basis and implemented on a number of Navy orders. The results of research. The systems of dynamic control available at the Navy are an effective tool for early detection of borderline functional States of seafarers; determination of the working capacity stage in which the specialist is currently located; development of recommendations for the implementation of corrective measures. However, in real life, these systems are practically not used, there are no guiding documents regulating their application. Implementation of such automated systems on other ship projects requires adaptation and improvement of such systems. In addition, the Navy has no technical means to monitor the functional status of personnel directly during the performance of particularly complex tasks, the struggle for survivability and other extreme situations. Conclusion. The basic concept of screening control and monitoring of the naval personnel functional state in the process of professional activity is proposed.

Relevance. The study of age-related features of microcirculation in periodontal tissues, using non-invasive functional research methods, allows us to develop the optimal range of therapeutic measures, as well as form a “personalized therapeutic case”.Purpose. Study of the functional state of the microvasculature in the tissues of the parodont in individuals of various age groups.Materials and methods. A standard dental examination of 80 patients was carried out, the sample of participants was ranked in 4 groups by age: 1 group – 12 years old, 2 group – 15 years old, 3 group – from 16 to 18 years old, 4 group – from 22 to 24 years old. Hygiene and periodontal indices were determined for all patients, such as papillarymarginal-alveolar (PMA) in the Parma modification, the Mulleman bleeding index in the Cowell modification (SBI), and the simplified Green Vermillion index of oral hygiene (OHI–s), caries intensity indicators for a permanent bite (CPI), as well as ultrasound dopplerography of periodontal tissues using the apparatus "Minimax-Doppler-K".Results. When studying microcirculation in periodontal tissues, distinctive characteristics of linear (Vas) and volumetric (Qas) blood flow rates, as well as indicators of pulsation indices (PI) and peripheral resistance (RI) in people of different age groups were recorded.Conclusions. This study confirms the presence of various hemodynamic indicators of periodontal tissues in the studied groups, which is due to structural features of the circulatory system in age periods.

In the context of the reform of the Armed Forces of the Russian Federation, the issues of recruiting troops with healthy, physically developed and mentally stable young conscripts are of paramount importance. Only citizens "A" - fit for military service and "B" fit for military service with minor restrictions are subject to conscription. When analyzing the results of medical examination of persons of military age, it was found that over the studied period of time, fitness for military service for health reasons decreased by 3.8% (from 78.3% in 2016 to 74.5% in 2020). However, despite the general decrease in fitness for military service, there is an increase in the fitness for military service "A" by 13.5% (from 23.4% in 2016 to 36.9% in 2020). Every year, during the period of work of the draft commissions, a significant number of citizens (more than 10%) were sent for additional examination to medical organizations. As a rule, the examination of conscripts was carried out on an outpatient basis (up to 85%) and much less often in an inpatient setting (up to 15%). The first place was occupied by diseases of the musculoskeletal system and connective tissue, which accounted for 24.9%. Mental and behavioral disorders ranked second with an indicator of 18.7%. The third place was taken by diseases of the circulatory system - 14.9%. Diseases of the eye and adnexa ranked fourth - 8.2%. Diseases of the digestive system were less common, accounting for only 4.5%. Thus, in total, the listed diseases accounted for 71.2% and were the main ones in determining the fitness of conscripts for military service for health reasons.

Evidence is presented for a significantly wider spread of the first two stages (mild and moderate) Colorectal Bradyarrhythmia Syndrome (CBS) compared with the third (severe — constipation) stage of this syndrome. Surveyed more than 2,500 medical professionals by the method of chronoenterographia. It was found that the incidence of mild CBS (about 60% of cases) and moderate stage of this syndrome (about 30% of cases) is almost an order of magnitude higher than the incidence of severe stage (about 10% of cases) of CBS. SCB has been shown to increase the risk of obesity by almost 3 times. It is shown that CBS contributes to a decrease in well-being, activity and mood, as well as a decrease in the quality of life. Screening for CBS and normalizing the circadian bowel rhythm with psyllium (mucofalc) in individuals who consider themselves healthy may contribute to early prevention of the risk of the metabolic syndrome.

The paper focuses on results of substantiating and selecting informative physiological criteria that can be used for assessing and controlling functional state and working conditions category taking into account physical and nervous-emotional loads borne by CNC- machinery operators. Basing on complex physiological and ergonomic studies and retrospective data analysis, we showed that workers from various occupational groups who dealt with physical labor had to face certain strain over a working shift. Such strains, given long-term working experience, could result in neuromuscular system overstrain and occupational diseases occurrence. We substantiated and developed informative physiological criteria that allowed assessing and controlling functional state and working capacity as well as working conditions category taking into account occupational activities. The present research involved using a set of occupational studies, physiological and ergonomic procedures as well as clinical and statistic ones for examining peculiarities related to functional state of workers’ bodies under exposure to occupational factors taking into account specific working tasks and loads. It allowed us to substantiate labor intensity assessment. Our research results revealed that there was a strong correlation between hand muscles endurance to static exertion (decrease in % by the end of a work shift) and working conditions category given local and overall muscular loads borne by workers. This criterion is recommended for control over functional state and working capacity taking into account occupational peculiarities and gender-related differences. It is necessary to accumulate scientific data for confirming a similar correlation between overall physical working capacity (OPWC) and working conditions category. Results obtained via physiological research were used for developing prevention activities for workers.
