An indicators analysis of the first-graders functional state and vegetative homeostasis obtained in the initial period of adaptation to the educational environment revealed gender differences in the rates of the adaptation process to new learning conditions. It has been established that girls’ adaptation mechanisms turn on earlier than boys’, with their similar orientation. The article provides an experimental justification of the indicators use legitimacy for heart rate variability to assess the functional state of the body in the acute period of adaptation to the educational environment. The importance of teacher physiological literacy for the optimization of the educational process is substantiated. The results of the study are convincing evidence of the knowledge importance for the physiological foundations of the occurrence and course of physiological and mental processes, stable individual psycho-physiological characteristics for the organization of the learning environment, corresponding to the functional capabilities of the body. This argument is also confirmed by many years of experience among master students key competencies development, which allow using such an objective criterion as the current functional state of the body to ensure, through the joint efforts of parents, teachers, psychologists, and doctors, the correction of the educational environment and psycho-physiological resistance of individual to it. The established differences in the dynamics of heart rate variability indicators for girls and boys can be used to form a health-saving program in school settings.

Murmansk Region

The Murmansk region is characterized by a number of specific climatic and geographical features: a polar night, a long snowy period, an unstable geo-heliophysical setting. All of the above factors have a negative impact on children with disabilities. The article describes the application of the method of analysis of heart rate variability to assess the dynamic changes in the functional state of the body of preschool children with general speech underdevelopment, as well as with stuttering. The work was carried out on the Kola Peninsula in the period of the exit from the «polar night», when exacerbations of somatic diseases are most often recorded in children, and there is a decrease in the immunological reactivity and adaptation potential. The main purpose of this work was to conduct research on the selection of methods for the functional diagnosis of a child’s body in the Kola North to track the state of the state during the educational process on the basis of a preschool institution during the most unfavorable periods. Functional diagnostics included weekly dynamic measurements of the functional status of children of both groups on a non-invasive cardiac rhythmograph, followed by mathematical processing of the main cardiorhythmographic parameters. The use of heart rate variability analysis makes it possible to identify differences in the functional state of preschool children with various speech disorders associated with the nosological structure of the defect. In addition, the use of this method allows you to track changes in the state of children in the course of the educational process in preschool institutions and to adjust the flow of information, taking into account the individual characteristics and adaptive capacities of children with speech disorders.

Currently, the problem of improving the quality of the training process in both professional and novice athletes is a priority for experts in the medical and biological support of sports all over the world. For these purposes, various biofeedback procedures, including the method of solving specialized motor-cognitive tasks on the stabilometric platform [1], have been actively used in recent years as extra-training means to improve sports performance. At the same time, we should note that one of the most informative biological signals that allow to judge about the change in the functional state of the body of the tested athletes in the process of sports training is the dynamics of heart rate variability (HRV) [2]. HRV analysis is widely used as a non-invasive and reliable tool for assessment of vegetative control of human cardiovascular system [3]. Numerous literature sources confirm the prospect of using this method for the purposes of sports physiology [4] However, changes in HRV in highly qualified athletes when solving complex motor and cognitive tasks, as of today, still remain unstudied. The aim of the present study was to assess changes in heart rate variability in highly qualified orienteering athletes when solving complex coordination tasks on biocontrol of a virtual object using a stabilometric platform ST-150. Seven days training with biofeedback control on the stabilometric platform resulted in a significant increase of such HRV temporal indices as SDNN – by 8,9 % (p<0,01), RMSSD – by 42,3 % (p<0,05), pNN50 – by 77, 1 % (p<0.05), CV – by 25.3 % (p<0.01), as well as heart rate reduction by 10.5 % (p<0.05), which indicates an increase in functional capabilities of the athletes’ bodies, strengthening vagus effects on cardiac rhythm. The results of geometrical analysis have shown that biofeedback according to reference reaction leads to reliable increase of values of index of mode of cardiointervals by 9,7 % and increase of variation range of histogram of cardiointervals by 21,4 % as well as decrease of values of mode amplitude by 19,2 % and tension index of regulatory systems of the body by 29,6 % (p<0,05), which testifies to improvement of adaptation possibilities of the body of tested sportsmen under the influence of this type of biocontrol. Analysis of spectral components of heart rhythm in orientation athletes after 7-day training with biofeedback control has shown significant increase in TP by 36 %, LF – by 37,7 %, HF – by 88,2 % as well as decrease in LF/HF by 28,2 % (p<0,05), which testify to increase in general variability of heart rhythm, activation of parasympathetic regulation circuit, increase in functional capabilities and reserves of tested athletes organism.

AbstractThe vagus nerve is the largest autonomic nerve, innervating nearly every organ in the body. “Vagal tone” is a clinical measure believed to indicate overall levels of vagal activity, but is measured indirectly through the heart rate variability (HRV). Abnormal HRV has been associated with many severe conditions such as diabetes, heart failure, and hypertension. However, vagal tone has never been directly measured, leading to disagreements in its interpretation and influencing the effectiveness of vagal therapies. Using custom carbon nanotube yarn electrodes, we were able to chronically record neural activity from the left cervical vagus in both anesthetized and non-anesthetized rats. Here we show that tonic vagal activity does not correlate with common HRV metrics with or without anesthesia. Although we found that average vagal activity is increased during inspiration compared to expiration, this respiratory-linked signal was not correlated with HRV either. These results represent a clear advance in neural recording technology but also point to the need for a re-interpretation of the link between HRV and “vagal tone”.

Addiction is a devastating disease of the body, the mind, and even the personality. Recent research shows that heart rate variability biofeedback can help the alcoholic/addict recover in three crucial ways, namely (1) treating the associated comorbidities (depression, anxiety, chronic pain), (2) treating the physiology around craving, and (3) returning to a loving and nurturing relationship with one's own body instead of an abusive and exploitive one.

Abstract: Introduction. Increasing information loads can lead to the development of professional stress and work-related illnesses in knowledge workers. The development and implementation of modern methods of control and correction of the functional state of employees in the conditions of activity is relevant. The study aims – to explore the dynamics of the functional state of knowledge workers in the conditions of modeling the cognitive load on the computer and during the training on neurofeedback (NFB) based on the parameters of the electroencephalogram (EEG). Materials and methods. 17 researchers (4 men and 13 women aged 22-63 years (34.8±3.4), with an average work experience of 12.1±3.3 years) participated in the study on the basis of voluntary informed consent. Results. A significant increase in the index of the alpha rhythm was shown by 29.4% of the subjects. It was found that the total power of the spectrum of heart rate variability (HRV) is higher, the adaptive risk is lower in the group that successfully passed alpha training (p<0.05). According to the results of continuous personalized heart rate telemetry, the dynamics of the functional state (FS) during the examination was determined for each subject. Conclusion. A significant influence of the state of neurohumoral regulation systems and adaptive reserves of the body on the success of the biofeedback training was established, which is the basis for the development of methodological approaches to the correction of FS, taking into account individual optimal management strategies.
