DINAMICS OF CHANGES OF HEART RHYTHM IN FOREIGN STUDENTS IN THE PROCESS OF AN ANNUAL TRAINING CYCLE

Abstract

The article presents the results of dynamic monitoring of the functional status of foreign students by using mathematical analysis of heart rate variability at various stages of academic year – autumn and spring educational semesters, winter and summer examinations. Strengthening the influence of the parasympathetic department of the autonomic nervous system was revealed during the intersessional period – the autumn and spring time of the academic year. In the winter examination session, the contribution of the sympathetic spectrum to the regulation of the heart rhythm was noted, in the summer session, an even greater shift in vegetative balance towards the sympathetic link of the VNS and an increase in the degree of centralization of the heart rhythm, indicating emotional stress and a functional imbalance in the cardiovascular system of students.
