Features of autonomous regulation in young subjects with increased vestibular analyzer sensitivity

Abstract

Vadzyuk S. N., Shmata R. M. Features of autonomous regulation in young subjects with increased vestibular analyzer sensitivity. AbstractIntroduction: Each person's body have adaptation during the load due to different changes in the cardiovascular system. One of the first systems that responds to any factors and is actively involved in the processes of adaptation is the autonomic nervous system. It is known that as a result of excitement of the vestibular analyzer kinetosis develops -"motion sickness", which is accompanied by nausea, dizziness, unsteadiness of gait, general weakness. In this regard, assessment of the functional state of the body and its adaptive reserves continues to be one of the most important problems of modern physiology and medicine.The purpose of the study was to evaluate the features of autonomous regulation in subjects with increased sensitivity of the vestibular analyzer.Materials and methods: 60 people between the ages of 18-19 were examined. Vestibular sensitivity was determined with a help of questionnaire. The state of the autonomic nervous system was determined by analyzing heart rate variability using a 5-minute ECG registration technique. The registration and recording was performed by the «PolySpectr +» computer program.Results and discussion: Based on the questionnaire, the students were divided into 2 groups: with proper and with increased vestibular sensitivity. In students with proper vestibular sensitivity, the LF / HF ratio of 1.06 indicates a balanced type of autonomic heart rate modulation. The analysis of spectral indices in subjects with increased vestibular sensitivity 12 showed a lower overall power of the spectrum, which indicates less functional reserves of the organism. We set much higher HF waves, which indicates an increase in the activity of the parasympathetic system. This is also indicated by the LF / HF ratio of 0.59. When considering the rhythmograms of subjects with increased vestibular sensitivity, 64% of 1-st grade rhythmograms, 20% of 2-nd grade rhythmograms and 16.6% of 3-rd grade rhythmograms were registered. When assessing rhythmograms of the 3-rd class, it can be concluded that the level of functional reserves of subjects with increased sensitivity of the vestibular analyzer can be reduced, which may lead to a decrease in the adaptive capacity of these subjects. Conclusions:In subjects with increased vestibular sensitivity, the parasympathetic autonomic nervous system makes the greatest contribution to the regulation of cardiac rhythm.Key words: increased sensitivity of the vestibular analyzer, autonomous regulation, functional reserves of the organism, rhythmograms.

Investigating the predictive contribution of attitude towards life and belief system on self-resilience and psychological toughness of cancer patients about the mediating role of emotion regulation

“…The present research results align with the results of Taylor and Qahi (2003) [29]. They suggest the possibility that the effects of stress are adjusted to a large extent with the help of meaning in life, and this is consistent with the theory of Labetsi (1999) that the development of schema considers positive things to overcome tension [30]. Also, the results showed that the belief system could significantly predict cancer patients' resilience through the mediation of emotion regulation.…”
