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.

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.

Summary Study aim: Regular exercise training is thought to modify cardiac autonomic control. One of the body’s responses to training stimuli is heart rate variability (HRV). The use of HRV in the management of sport training is a common practice. The objective of the present study was to assess the impact of the physical activity level on HRV of 1st league national volleyball players prior to and during the competition period. Materials and methods: The study involved 11 players whose HRV was evaluated during the two analysed training periods. Selected indicators of spectral analysis (total power, %VLF, % LF, % HF powers, LF n.u, HF n.u, and LF/HF powers) as well as time analysis (HR, RR, RMSSD, NN50) were assessed on the basis of recordings. Results: The studies conducted in the pre-competition and competition periods showed significant differences in the parameters of spectral VLF% analysis and time NN50 analysis. In the competition period, a significant increase in VLF [%] may be the result of increased psycho-physical arousal, when compared to the pre-competition period. ] Conclusions: Resting bradycardia, assessed on the basis of time analysis indicators, may be the result of internal changes in the sinus node, which reflects the impact of long-term training on the cardiac conduction system. A high level of physical activity of volleyball players in the tested periods could have contributed to a reduction in vagal tone and a shift in the balance of the autonomic nervous system in the direction of the sympathetic system, which may be the result of overtraining

Mechanisms of regulation of cardiac rhythm have many individual features, which are conditioned by age, sex, training of the organism, strength and nature of external influence, constitutional features of the organism. The purpose of the work is to determine the relationship between cardiointervalographic indices and parameters of the external structure of the body in highly skilled wrestlers of the mesomorphic somatotype. The study involved 24 wrestlers between the ages of 17 and 21 with a high level of sportsmanship and more than 3 years of experience. All of the wrestlers were of medium weight and engaged in free and Greco-Roman wrestling. We conducted a study of heart rate variability on the cardiac computer diagnostic complex “OPTW” following the recommendations of the European and North American Cardiac Association (1996). The indices of vegetative homeostasis according to Bayevsky, variational heart rate, statistical and spectral cardiointervalographic indicators were determined. Anthropometry was performed according to the method of V.V. Bunak (1941), somatotypological study – by the calculated modification of the Heath-Carter method (1990), determination of the component composition of body weight by the method of Matejko (1992). In the package “STATISTICA 5.5” correlation analysis was performed using the nonparametric Spearman statistical method. It was found that in the wrestlers of the mesomorphic somatotype, the variations of the pulsometry had the highest number and strength of reliable correlations with constitutional parameters, most of which were inverse of the mean force. All statistical indicators of heart rate variability with indicators of the external structure of the body had only inverse significant correlations. The least significant correlations were found for spectral indices and parameters of vegetative homeostasis. According to the results of the correlation analysis in the wrestlers of the mesomorphic somatotype, we can assume that with the increase of total, longitudinal, circumferential, transverse body sizes and muscle and bone mass, the variability of the heart rhythm of the sympathetic department of the autonomic nervous system will be more pronounced.

Heart rate variability (HRV) biofeedback (BFB) can be used to reduce activation of the sympathetic nervous system (SNS) and increase activation of the parasympathetic nervous system (PNS). A growing body of research suggests that increased arousal of the SNS contributes to the sustained state of postconcussion syndrome (PCS). It has also been postulated that underactivation of the PNS may also play a role in the postinjury state of autonomic dystonia, wherein the autonomic nervous system is in a state of imbalance and does not return to normal. In addition to autonomic imbalance, patients who are generally advised not to engage in physical exertion until asymptomatic from concussion, are known to experience secondary symptoms of fatigue and reactive depression. Recent research has established that such symptoms can delay the recovery from concussion indefinitely. By addressing both autonomic dysfunction and the secondary symptoms of depression and anxiety, HRV BFB may be an effective treatment for PCS by strengthening self-regulatory control mechanisms in the body and improving autonomic balance. Recent studies have suggested that HRV BFB has a positive impact in reducing stress and anxiety among athletes, and concussed athletes with higher perceived control over their symptoms have been shown to have faster recoveries post-injury. The primary purpose of the following case study was, therefore, to assess the feasibility of implementing HRV BFB with a concussed athlete suffering from postconcussion syndrome (PCS). The second objective was to prospectively examine the impact of ten weeks of HRV biofeedback on refractory postconcussion symptoms. During this pilot case study, the athlete attended 10 weekly sessions of HRV BFB, according to the protocol set forth by Lehrer, Vaschillo, and Vaschillo (2000). After 10 weeks of HRV biofeedback, the athlete exhibited clinically significant improvements in total mood disturbance, postconcussion symptoms, and headache severity. The results suggest that HRV BFB may be a useful adjunctive treatment for PCS, associated with increases in HRV and enhanced cardiovagal activity. Given these findings, a randomized controlled trial is warranted.

Introduction Sound vibrations have a profound impact on the body and the mind with evidence confirming reduced anxiety and increased wellbeing. The likely reason for driving the benefit is relaxation. The Himalayan Singing Bowls, used for therapeutic intervention to enhance the individual’s emotional & physical wellbeing, may facilitate faster and deeper relaxation as compared to simple, supine relaxation. Aim of the Study The study aimed to validate the hypothesis that short 20 minutes sessions to relax with the help of the Himalayan Singing Bowl (HSB) could provide better depth of relaxation as compared to Supine Silence (SS) based on the objective assessment of physiology parameters i.e. Stress Index & Heart Rate Variability (HRV). Methods Seven metal Himalayan singing bowls were used in a particular sequence learned from an expert teacher for 16 subjects. The SS group consisted of 17 subjects. The HRV data was measured by the Emwave Pro device and analyzed using Kubios HRV Premium software. The analysis compared key HRV parameters within and between the groups. Result Overall, as expected, both groups achieved relaxation as measured by changes in HRV parameters. However, further analysis confirmed a more consistent relaxation, as measured by a statistically significant reduction in stress index and an increase in HRV, for HSB group. The HSB group achieved more consistent depth of relaxation during each subsequent 5 minutes interval throughout the session as compared to SS group. Conclusion The study confirms that singing bowls sessions can be leveraged as a tool for inducing good quality relaxation response (increased parasympathetic tone, reduced stress) to facilitate healing and energy recovery in just 20 minutes and achieve significant health benefits. More comprehensive studies must be conducted to further evaluate the findings with more sample size, different methods of relaxation and varied demographics.

Introduction. The article summarizes the results of studying the process of students’ adaptation to the learning environment in a wide range of degree programmes provided by higher educational institutions. The purpose of the article is to identify the characteristic features of students’ psychophysiological adaptation to the learning environment, taking into account the peculiarities of autonomic regulation, with the subsequent assessment of the effectiveness of using RSA-BFB therapy. Materials and Methods. The study involved 209 second-year medical and biological students. The study of neurodynamic characteristics was carried out using an automated psychophysiological complex. Heart rate variability indicators were evaluated by means of cardiorhythmography. The authors conducted a comparative analysis of the mean values and identified the correlation between neurodynamic characteristics and indicators of heart rate variability of students doing academic degrees in various fields. RSA-BFB therapy was used to increase students’ adaptive capabilities. Results. The characteristic features of adaptive reactions were revealed depending on the initial vegetative tone and the type of functional response. The combination of psychophysiological and medico-biological constitutional approaches used in the work enabled the authors to expand and clarify the ideas about the mechanism of the functional self-regulation system and classify the types of adaptive reactions in the process of educational: adaptive, compensatory and maladaptive. After the RSA-BFB therapy for students prone to maladaptive reactions, in comparison with the control group, there was an improvement in the strength of the nervous system and the mobility of nervous processes. Using RSA-BFB therapy contributed to overcoming chronic stress and developing reaction patterns inherent in adaptive types. Conclusions. The use of RSA-biofeedback therapy, taking into account the individual-typological characteristics, has contributed to balancing ergotropic and trophotropic processes, restoring the body's functional reserves and improving the efficiency of adaptation to learning environment.

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.

The topic of sports, physical fitness and adaptive abilities of a person to the influence of physical activity of different intensity has become highly relevant in recent years. The aim of the work is to establish correlations between the indicators of heart rate variability and parameters of the external structure of the body in young athletes of mesomorphic somatotype. The study involved 29 athletes between the ages of 17 and 21 with a high level of sportsmanship and more than 3 years of experience. All athletes had a track and field athletic load with maximum (100 m, 200 m and 110 m hurdles) and submaximal (running on 400 m and 800 m) work intensity. We conducted a study of heart rate variability on the cardiac computer diagnostic complex “OPTW” following the recommendations of the European and North American Cardiac Association (1996). Variable heart rate, statistical and spectral cardiointervalographic indices were determined. Anthropometry was performed by the Bunak method (1941), somatotypological study – by the calculated modification of the Heath-Carter method (1990), determination of the component composition of body weight by the method of Matejko (1921). In the package “STATISTICA 5.5” correlation analysis was performed using the nonparametric Spearman statistical method. Cardiointervalographic findings were found to be statistically significantly correlated with a small number of body sizes and somatotype components and body weights in adolescent athletes belonging to the mesomorphic somatotype. Indicators of variational heart rate did not have numerous reliable and unreliable relationships of average strength with somatic parameters. The data of correlation analysis of indices of variational pulsometry showed that in athletes with increase in width and thickness of the torso and decrease in the circumference of the shin and chest was more pronounced sympathicotonia, and with the reduction of fat component increased the influence on the heart of the parasympathetic system. Statistical indicators of heart rate variability with constitutional parameters had significant inverse correlations of mean power. Among all statistical indicators of heart rate variability, the PNN50 had the strongest and most significant correlations with anthropometric dimensions. The least significant correlations with constitutional characteristics in mesomorphic athletes had spectral indices related to skin-fat thickness, trunk diameters, and lower limb segment circumferences.
