The study is devoted to the study of the influence of individual psychological characteristics of the personality of aviation specialists on the tolerability of moderate degrees of hypobaric hypoxia, simulated in a pressure chamber. The study included the assessment of physiological parameters (blood pressure, heart rate, arterial blood saturation, Roufier index) and psychophysiological indicators (critical frequency of light flickering fusion, complex sensorimotor response, indicators of subjective assessment of the state (SAN test)) depending on the level of neuroticism, extroversion and personal anxiety level. As a result of the study, it was found that the functional state of the body of subjects with high levels of neuroticism in hypobaric hypoxia changes significantly than in subjects with low levels of neuroticism, which is confirmed by a more pronounced decrease in health, activity and mood by 17.5% (p 0.01), 16.9% (p 0.05) and 9% (p 0.01), respectively, an increase in the time of complex sensorimotor response by 12.6% (p 0.01), as well as more pronounced functional changes in the cardiovascular system. It was revealed that changes in some physiological parameters in extroverts had a large negative dynamics in hypoxia, so the increase in the Roufier index in the group of introverts at 30, 60 minutes and after the rise by 97.3%, 98.6% and 15.1%, respectively, against an increase of 118.2%, 123.6% and 16.4% in the group of extroverts was revealed. In the group of extroverts, an increase in the time of complex sensorimotor response after the end of the study was found by 8.0% (p 0.05), an increase in critical frequency of light flickering fusion compared to the indicators obtained before the rise by 5.2% (p 0.05). It is established that the functional status of subjects with high levels of trait anxiety had a more pronounced negative trend in terms of the effects of hypobaric hypoxia, which is confirmed by a significant higher values of the Roufier index in groups with high levels of trait anxiety, with the background study, 30th, 60th minute and after rising; extending the time complex sensorimotor response to 45 minute 6.1% (p 0.05), and after altitude study by 9.5% (p 0.01); by the 40th minute of stay in the hyperbaric chamber the indicators of well-being decreased by 20.3% (p 0.01), activity by 18.8% (p 0.05) and mood by 13.7% (p 0.01). Thus, it was shown that in assessing the tolerability of moderate degrees of hypoxia, it is necessary to take into account the dependence of changes in the functional state of the organism on individual psychological characteristics.

Research  background  and  hypothesis.  Traditional  time  series  analysis  techniques,  which  are  also  used  for the analysis of cardiovascular signals, do not reveal the relationship between the  changes in the indices recorded associated with the multiscale and chaotic structure of the tested object, which allows establishing short-and long-term structural and functional changes.Research aim was to reveal the dynamical peculiarities of interactions of cardiovascular system indices while evaluating the functional state of track-and-field athletes and Greco-Roman wrestlers.Research methods. Twenty two subjects participated in the study, their average age of 23.5 ± 1.7 years. During the study standard 12 lead electrocardiograms (ECG) were recorded. The following ECG parameters were used in the study: duration of RR interval taken from the II standard lead, duration of QRS complex, duration of JT interval and amplitude of ST segment taken from the V standard lead.Research  results.  Significant  differences  were  found  between  inter-parametric  connections  of  ST  segment amplitude and JT interval duration at the pre and post-training testing. Observed changes at different hierarchical levels of the body systems revealed inadequate cardiac metabolic processes, leading to changes in the metabolic rate of the myocardium and reflected in the dynamics of all investigated interactions.Discussion and conclusions. It has been found that peculiarities of the interactions of ECG indices interactions show the exposure of the  functional changes in the body at the onset of the workload. The alterations of the functional state of the body and the signs of fatigue, after athletes performed two high intensity training sessions per day, can be assessed using the approach of the evaluation of interactions between functional variables. Therefore the evaluation of the interactions of physiological signals by using time series analysis methods is suitable for the observation of these processes and the functional state of the body.Keywords: electrocardiogram, time series, functional state.

The aim was to compare methods of body fat measurement in different BMI groups. An additional aim was to discuss differences reflecting the structural and functional changes of fat tissue. The study group included 130 adult Caucasian women stratified by body mass index (BMI): 18-24.99 (n=30), 25-29.99 (n=26), 30-34.99 (n=33), 35-39.99 (n=30), and BMI≥40 (n=11). Bioelectrical impedance was performed using Tanita TBF 410 GS, Bodystat 1500, and Omron BF 300. A caliper type Best was also applied. Correspondence of four methods with DEXA was assessed using the Bland-Altman and ANOVA analyses. Measurements by BIA were not significantly different from DEXA up to BMI of 30, but DEXA significantly overestimated in the higher BMI subgroup by all three methods. Caliper measurement significantly underestimated DEXA in all BMI subgroups. BIA methods overestimated DEXA for the obese subjects. Tanita did statistically the best. The Caliper test appeared less preferable than the BIA methods, especially in the higher BMI subgroup. DEXA and Caliper measurements seem to be the best estimate of structural (anatomical) fat quantity. We hypothesize that BIA methods could also measure some other physiopathological conditions like inflammation, hydration or cell infiltration of fat.

The purpose is providing rationale for the distance duration (15 km) of the All-Russian physical culture and sports training program “Ready for Labor and Defense” hiking trip among young men (6th stage). The participants in this experiment were students (n=16) aged 18-21. The following physiological methods were used: heart-rate monitoring, measurement of blood pressure and subsequent determination of cardiac output, recording and interpretation of electrocardiograms according to the method of professor A. Zavyalov, as well as mental state determination by means of the “Well-being, energies, mood” method. Physical efficiency dynamics of teenagers by key indicators within the research at all key-points does not reflect significant functional changes in the body that would let us state the accumulation of great fatigue (ECG=14±2.38, WAM index was 5.2 at the beginning and 4.9 at the end, heart-rate =97 BPM). The main indicators of the dynamic analysis of the functional state of participants within the hiking trips allows us to conclude that a distance of 15 km is optimal for teenage boys. However, variable conditions are possible for in the form of an increase in distance to 18 km, final recommendations require additional research

The term Geriatrics is made by union of two Greek word first ‘geras’ (old age) and second ‘iatros’ (physician) and derived from Greek root “gergero- geronto” meaning old age or the aged or especially one receiving special care. Geriatrics is the branch of medicine that focuses on health promotion and prevention and treatment of disease and disability in later life. In India population of the elderly has been increasing steadily since 1961 as it touched 13.8 crore in 2021, growing faster due to decrease in death rate, according to a study by National Statistical Office (NSO). Ageing is the process in which structural and functional changes occur with passage of time. Thus study of all aspects of ageing including physiological, pathological, psychological, economical and sociological problems is termed as Geriatrics. With advancing age, several changes take place in the body, in the external appearance as well as in Dosha, Dhatu, Mala, Agni, Oja level, also on the mental functions. In Ayurvedic texts, there are many ways given for prevention and promotion of health, one of them is Dinacharya (daily regimen), which is most important part to maintain a healthy and happy life. The importance of appropriate daily routine cannot be underestimated. It set the wheels in motion for entire day, bringing a sense of calm and well-being. It gives the body, mind and spirit the chance to start afresh.

Functional Changes

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 article reveals the influence of physical exercises on the development of morpho-functional indicators of student youth. It was found that in students who regularly exercise, physical development indicators are within normal limits. In addition, exercise improves the psychological state of those who engage, increases motivation for physical education, improves well-being. The modern focus on the creative assimilation of physical culture by the future specialist requires an orderly system of effectiveness on his intellectual, emotional, volitional and practical activities. This allows us to talk about physical education as an important way of forming a personality, citizen and future specialist, purposeful pedagogical process of involving student youth in the values of national physical culture. The purpose of physical education in higher education - the formation of physical culture of personality, creation conditions for general and professional training of students and increase on this basis of intellectual, creative and cultural wealth of the state. Achieving this goal involves the formation of the necessary motivational core of physical education and self-education, systematic physical culture and sports activities and development of physical abilities. It is known that movements are the final expression of almost all processes occurring in the body. Unmet need for muscle activity has negative consequences for the functional state of the body and physical performance. Systematic physical exercises for a long period of time naturally lead to specific changes in the physical development of students. At the same time, the data of physical development studies become especially important when they are associated with indicators of the functional state of the organism, its efficiency and preparedness.

: Physical exercise (PE), notoriously, promotes a state of general well-being, throughout the entire human lifespan. Moreover, maintaining an adequate and regular PE habit results to be a powerful preventive factor towards many diseases and may also help in managing existing pathological conditions. PE induces structural and functional changes in various districts of the body, determining biological and psychological benefits. Additionally, in elderly, PE might represent a remarkable tool reducing cognitive impairments related to the normal aging processes and it has also been found to have an impact in neurodegenerative diseases such as Alzheimer’s disease. The present review aims to provide an overview about PE effects on hippocampus, since it is one of the brain regions most susceptible to aging and, therefore, involved in diseases characterized by cognitive impairment.

Introduction. The study of the physiological status of representatives of power structures at different stages of service is very relevant.Purpose: a comprehensive assessment of the functional state of the body of OMON fighters before and after a 4-month business trip on perform a special task associated with health and life risks. Materials and methods. 34 OMON fighters of the Komi Republic were examined before the trip and after a 4-month trip to the North Caucasus, where they constantly experienced stress. To assess the functional state of the body, a complex of anthropometric, physiometric, psychophysiological, physiological and biochemical studies was used.Results and its discussion. Before the trip, the fighters showed an increase in the time of the visuomotor reaction, the index of functional changes, the myocardium index, the centralization index, the activity index of regulatory systems, blood pressure indicators and other changes that indicate the activation of free radical oxidation processes, and the appearance in individuals of prenosological and even premorbid conditions. In most of the examined patients, a shift in the autonomic balance was found towards strengthening the sympathetic link in the regulation of heart rhythm. Hypovitaminosis was found in many fighters. After a trip, the functional state deteriorated in most indicators (increased blood pressure, personal anxiety, cholesterol, etc., decreased life index and hemoglobin content, etc.) and the number of people with depleted regulatory systems almost doubled.Conclusion. In general, the body of OMON fighters experiences increased functional stress with signs of obvious stress both before a trip to an area dangerous for health and life, and in the first days after returning to places of permanent residence in the North. In this regard, they need additional health and rehabilitation measures related to optimization of the regime of work and rest, activation of physical education, rationalization of nutrition and strengthening the work on the psychological impact.
