Response of the cardiovascular system to heart rate variability biofeedback intervention in adolescents with different autonomic nervous tone living in northern and southern regions
BACKGROUND: The cardiovascular responses of adolescents during self-regulation are contingent upon their initial autonomic tone and place of residence. AIM: To investigate the dynamics of cardiovascular system indices during heart rate variability biofeedback (HRV BF) training in adolescents with different initial autonomic regulation of heart rhythm, taking into account their residence in the northern and southern regions. MATERIAL AND METHODS: …
Neurophysiologic Reactions during Heart Rate Variability Biofeedback Session in Adolescents with Different Risk of Internet Addiction
The aim of this study was to determine electroencephalogram (EEG) in a session of heart rate variability biofeedback (HRV BF) in adolescents with different Internet addiction (IA) risks. In total, 100 healthy adolescents aged 16-17 years with minimal risk of IA (Group I, 35%), pronounced risk of IA (Group II, 51%), and stable pattern of IA (Group III, 14%) using the Chen Internet Addiction Scale were examined. HRV and EEG parameters were determin…
Effects of Heart Rate Variability Biofeedback Sessions on the Dynamics of the Eeg Spectral Power During Experimental Hypothermia
Introduction: Determination of individual reactions of the nervous system during self-regulation under experimental cold conditions has a potential to contribute to better understanding of the "physiological costs" humans "pay" for adaptation to the climatic factors of the Arctic. Aim: To study the dynamics of the spectral power of the electroencephalogram (EEG) during heart rate variability biofeedback (HRV BF) sessions in experimental hypotherm…
Brain Activity in Adolescents With Different Internet Addiction Risks
Aim: To study electroencephalographic (EEG) changes in adolescents with different risks of developing Internet addiction (IA). Methods: This cross-sectional study included 1б-17 years-old adolescents (n = 55) permanently living in the Arctic Russian town of Arkhangelsk. Risk of IA was assessed using the Chen Internet Addiction Scale (CIAS). By the results of the CIAS test all adolescents were divided into three groups: I - minimal risk of IA, II …
Changes in cardiovascular indices and bioelectric activity of the brain in response to cold exposure in young men
The aim was to study changes in cardiovascular indices and electroencephalogram (EEG) characteristics in response to short-term general air cooling of the body in young adults. Methods. The sample consisted of 13 healthy men aged 18-21 years who were permanent residents of the city of Arkhangelsk (Northwest Russia). The spectral power (SP) of EEG rhythms was assessed using an electroencephalograph (Neurosoft, Russia). Heart rate variability (HRV)…
Features of Neurophysiologic Status in Childhood and Adolescence (Literature Review)
In the first part of the review the historical aspect of scientific fields of age neurophysiology has been provided, age-related features of morphologic and functional development of the brain and their reflection in his bioelectric activity have been considered. It has been shown that the morphological maturation of different brain structures reflected both in the psycho-physiological development of the child and in changes of amplitude-frequenc…
EEG-reaktsii v dinamike kardiobioupravleniya u podrostkov s razlichnym vegetativnym tonusom, prozhivayushchikh na severnykh shirotakh
The character of the electroencephalogram (EEG) changes during a once procedure of heart rate variability biofeedback was considered in adolescents 14-17 years with different autonomic nervous types living in the different geographical latitudes and climatic, ecological conditions of the European North: the Subpolar (64°30' N) and Polar (67°40' N) areas. More intensive reduction of theta EEG activity (p < 0,05-0,001) with a predominance of the dy…
Age Features of Cardiovascular System Functional Parameters in Adolescents Living in Different Arctic Areas
Age features of autonomic nervous regulation of cardiac activity in 426 healthy adolescents aged 14-17 years living in areas of different latitudes, climatic and ecological conditions of the European North - in the Subpolar (64°30' N) and Polar (67°40' N) areas have been detected. Assessment of the cardiovascular system status was carried out with the use of the heart rate variability (HRV) and blood pressure (BP) parameters. The share of persons…
Alterations of Dynamics of Human Electroencephalogram Spectral Parameters During Daily Geomagnetic Field Variations
The technique of identifying the nature of daily changes in spectral power relations of the basic rhythm brain activity and geomagnetic field variations has been proposed. There has been carried out an analysis of electroencephalogram (EEG) alpha activity spectral power recording at every minute in the morning, afternoon and evening during 5 days (12 recordings, 30 minutes each) in three healthy volunteers compared to every-minute variations of t…
Physiological Basis of the Functional Biofeedback Methods
The review contains a definition and the essence of biofeedback functional methods. The historical, scientific aspects and the main hypotheses are given here explaining the mechanisms of biofeedback. Different techniques and methods of biofeedback are discussed, as well as the scope of the rapidly developing technology of biofeedback. Emphasis is put on physiological mechanisms and prospects of heart rate variability biofeedback methods of develo…
Variants of Eeg-Reactions During HRV Biofeedback Course in Adolescents With Different Initial Autonomic Nervous Tone
There was surveyed a character of brain bioelectric activity change during carrying out of biofeedback sessions by heart rate variability parameters (HRV biofeedback) in adolescents aged 15-17 years with different initial autonomic nervous tone. It has been established, that adolescents with the optimal autonomic nervous tone have high reactance of both autonomic nervous system parts. At the end of HRV biofeedback course there is more significant…
