Here was investigated the dynamics of indices of the functional state of the cardiovascular system in students during the educational load, followed by cold inhalation of lavender oil. The study was executed twice: before and after aromatherapy. For the evaluation of the functional capabilities of the cardiovascular system the registration and analysis of ECG were performed by means of the method of variation pulsometry with the use of the hardware-software complex, including portable electrocardiograph brand “Bio-Arm 001”, a personal computer with the software for automatic recording and analysis of ECG. In the experimental situation for each subject there were analyzed five-minutes ECG records. There were investigated statistical, histographical, integral and spectral parameters of the cardiac rhythm. Psychosomatic status of students was assessed by individual survey. The analysis of dynamic characteristics of heart rate variability showed that after the half-hour education load (the warming-up period) in the majority of the students there was observed the exertion of regulatory mechanisms of the heart rhythm. The preventive use of lavender ethereal oil contributes to the enhancement of adaptive capabilities of the body of students, optimization of regulatory mechanisms, and increased tolerance of the body to psycho-emotional loads. Against the background of the impact of lavender ethereal oil the adaptation to the training loads is running via the parasympathetic (more economical) type of regulation of the cardiovascular system of the body. Correcting influence of the odor of aromatic oils on the functional condition of the body may be caused to the fact that the perception of odors and treatment of olfactory information involves the most important parts of the brain: frontal cortex, hypothalamus, amygdala, a brain structure, limbic reticular structures et al., referred to morphological and functional substrates of emotional reactions.

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.

Determining the maladaptation and adaptive capabilities of the body, in particular the cardiovascular system of volleyball player is currently advanced in sports medicine. The aim of the work is to establish correlations between cardiointervalographic indicators and parameters of external body structure in volleyball players of mesomorphic somatotype of juvenile age. The study involved 24 volleyball players aged 17 to 21 with a high level of sportsmanship and more than 3 years of experience. We conducted a study of heart rate variability on the cardiac computer diagnostic complex "OPTW" according to the recommendations of the European and North American Cardiac Association (1996). Indicators of autonomic homeostasis according to Baevsky, variation pulsometry, statistical and spectral cardiointervalographic parameters were determined. Anthropometry was performed by the method of Bunak (1941), somatotypological study – by the calculated modification of the method of Heath-Carter (1990), determination of the component composition of body weight by the method of Matejko (1992), correlation analysis by the method of Spearman was performed in the package "STATISTICA 5.5". Mesomorphic volleyball players were found to have the highest number and strength of reliable correlations with anthropo-somatotypological parameters, most of which were inverse and medium strength. Statistical, spectral parameters of heart rate variability and indicators of autonomic homeostasis with indicators of external body structure had few significant correlations. The girth of the hand in mesomorphic constitution volleyball players was statistically significantly related to the value of all statistical parameters and indicators of autonomic homeostasis by the method of Baevsky. According to the results of correlation analysis, we can assume that in volleyball players of mesomorphic somatotype with increasing the size of the mesomorphic component of somatotype, longitudinal, circumferential sizes and diameters of chest, arm, leg, neck will increase the impact on heart rate variability of the parasympathetic autonomic system.

Prenosological assessment of the functional state of students studying in different climatic and geographical conditions is a very important task, since it allows timely detection of conditions that precede pathologies in students and contributes to the preservation of health. Goal. Study of the state of the regulatory mechanisms of the cardiovascular system in foreign students living and studying in the midlands. Materials and methods. The study involved 342 first- and third-year students aged 20.0±1.9 years from India. The survey was carried out in the conditions of the low mountains (760 m above sea level, control group) and the midlands (1650 m above sea level). The main time and spectral parameters of HRV were recorded within 5 minutes using the hardware and software complex Psychophysiologist. Results. The comparative assessment showed that students living in the conditions of the midlands had low values of SDNN, TP, VLF, LF and HF and high indicators of AMo, HR, SI, which indicates the predominance of central regulatory mechanisms and the shift of the vegetative balance towards the sympathetic link in this group. Conclusion. The revealed changes in the spectral and temporal parameters of HRV in midlands students characterize the idea of a regulatory and adaptive state of the body, in which energy and metabolic resources are activated, primarily the circulatory system, aimed at maintaining homeostasis in changing environmental conditions.

Abstract The aim of this study was to test the impact of the Grasping Test (GT) on the female cardiovascular system and to ascertain the possibility of using this to replace the Orthostatic Tolerance Test (OT). In this study, 15 volunteer female students were examined, and their physiological parameters - their systolic (SBP) and diastolic blood pressures (DBP), and their heart rates (HR) - were compared. We found that the Orthostatic Tolerance Test (changing the position of the body from recumbent to upright) and the Grasping Test induced meaningful but similar changes in the functioning of the women’s cardiovascular system. The results confirm that there were significant similarities between the cardiovascular system measurements as produced through the Orthostatic Tolerance Test and the Grasping Test. The possibility of introducing the procedure into clinical practice is a crucial factor for continuing our research in the wider population.

The cardiovascular system is actively involved in the adaptive reactions of the body. The deterioration of adaptive processes decreases the functional capabilities of the heart. Arterial hypertension is often known as the main cause of fatal cardiovascular events in adults. The aim of our study was to determine the adaptive capabilities of the cardiovascular system of adolescents with non-inflammatory cardiomyopathies depending on physical activity’s level. There were examined 92 patients with arterial hypertension and connective tissue dysplasia, the mean age was 15,4 ± 1,33 years. In order to study tolerance to the minimum physical activity and its influence on the state of the cardiovascular system in children, the Ruffier test was conducted. The vegetative reactions of central nervous system were performed by the orthostatic test. The functional state of the myocardium was assessed according to the results of the ultrasonic Doppler study of the heart. As a result of the study, it was found that in connective tissue dysplasia and arterial hypertension adaptation mechanisms were affected, accompanied by a weakening of cardiac functional capabilities. This happens against the background of a decrease in the functioning of the left ventricle. These changes are accompanied by hyperactivation of the autonomic nervous system in patients in the studied groups. The physical activity and physical development of children affect the adaptive capabilities of a growing organism. This is due to the fact that the children in group with AH and CTD were less physically active than children without myocardial pathology. Adolescents who showed the reduced results of Ruffier's test and had regular sports sections need change of a mode of training and further inspection.

The author presents the results of a comprehensive assessment of working conditions and functional systems of the body of workers in the conditions of by-product coke production. Harmful factors of the working environment negatively impacting on the health indicators of workers, which is reflected in the high values of morbidity with temporary disability. Quantitative criteria for identifying risk groups and disability were determined depending on the professional group, work experience, gender and age. To calculate the risk range, the method of rationing of intensive indicators was used, which makes it possible to assess the effect of production on the morbidity of workers, as well as to use the results obtained for a comprehensive integral assessment of the likelihood of the risk of disability in the studied professional groups. Ranges of risk have been obtained, which will help to identify "risk groups" among workers requiring examination and preventive measures. Equations of multiple regressions for complex integral risk assessment are obtained, risk forecast for the studied professional groups is calculated. The developed mathematical model and equations of multiple regressions make it possible to calculate the stress levels of the functional systems of the body, to quickly assess the performance of a person both at the time of examination and in production conditions. The proposed method for assessing the impact of working conditions on health indicators can be used at mining enterprises when certifying workplaces and assessing working conditions. The developed methodological recommendations are used in the educational process to improve the quality of scientific research, to analyze the results obtained, as well as in production to simplify the procedure for assessing the impact of harmful production factors on workers and the scientific organization of labor.

Introduction. Regular physical load determines increase in functional capability of cardiovascular system. On the other hand, the cardiovascular system often appears as a conditional factor, which restricts organism adaptive abilities and limits general organism adaptation to the load. During physical load, not only cardiovascular system is activated, but also complex changes take place in the whole body. Therefore, with the aim to evaluate the functions of various systems, interrelation between them and systemic response of the body to physical load, a complex research on distinctive features of not only functional indices of the cardiovascular system, but also parameters reflecting interrelationship among functional systems of the body and speed of their changes is carried out. The goal of such complex research is the evaluation of adaptive and reserve capabilities of the athlete’s body and individualization and optimization of physical load. The aim of this study was to evaluate the speed of changes of parameters that characterize the functional condition of human organism of children and adolescents athletes and non-athletes controls. Materials and methods. One hundred sixty seven male athletes aged 14.8 (SD1.6, range 12-17 years) participating in basketball, rowing and cycling and168 healthy sedentary controls matched for age, sex and body surface area performed a graded exercise test (Mc. Master) on a cycle ergo-meter. 12 ECG standard derivations were synchronously recorded every second minute. During cycle ergo-meter integrated functional parameters, which could integrally and simple evaluate organism reaction to physical load, were assessed.Results. The present study demonstrates that before reaching the maximum of physical load, the speed of changes JT/RR in athletes and all functional parameters (HR, JT interval, RR interval, systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse blood pressure (SBP-DBP), JT/RR ratio) in the control group decreased and in the last step of physical load has increased. That suggests that during intensive exercise training limits of physiological changes can be exceeded in athletes. Conclusions. Analysis of speed of changes in functional parameters during physical load can be applied for the evaluation of functional state of the human body and the cardiovascular system and aiming to optimize and individualize physical load in athletic children and adolescents.
