Exam stress is one of the numerous causes of complex psychophysiological stress in students. One of the modern problems of electrophysiology is the study of the action mechanism of high levels of anxiety in students during and after the examination. The speed of development of the lifestyle of young people and an increase in the level of stress in the environment lead to a change in the relationship in the adaptive function of the body and the emergence of various kinds of deviations. Examination stress is accompanied by the emergence of many complex neurophysiological changes in the body, which negatively affects the life of young men. In all cases, young people strive to achieve their goals, which in itself leads to emotional stress. One of them is the study of the functioning of the nervous system during emotional stress and clarification of the role of various types of the higher nervous system in this. Despite a comprehensive study of this problem, this issue still remains relevant, and the study of the mechanisms of the anxiety process continues. The article presents the results of changes in the level of situational and personal anxiety of the examination process on the indicators of the autonomic nervous system in I and V year students, at the age of 17-21 years, having a type of phlegmatism. Before the beginning of the experiment, the type of temperament was determined by G. Eisenk test. Material and methods. To determine the level of situational and personal anxiety (emotional tension) of 17–21-year-olds, having the phlegmatic type of temperament, we used the method of expressive test two days before the exam, 30 minutes before the exam and 30 minutes after the exam. In all three groups, arterial pressure was measured using the Korotkova method and pulpator method of determining the heart rate per minute. Vegetative tone was calculated based on the Kerdo vegetative index. Results and discussion. The obtained results showed that 17-year-old phlegmatics-first-year students observed differences between the frequencies of cardiac contraction and arterial pressure two days before the exam, 30 minutes before the exam and 30 minutes after the exam. In all groups, the test had a sympathetic character, which testifies to the superiority of the sympathetic nervous system in the duration of the entire examination period. In 21-year-old students-phlegmatics course-vegetative indicators in two days before the exam, 30 minutes before the exam and 30 minutes after the exam differred slightly in comparison with 17-year-olds. Similarly, the Kerdo vegetative index of the 17-year-old students-phlegmatics and 21-year-old students-phlegmatics in all groups had the sympathetic character. This is also evidence of the prevalence of a sympathetic disorder of the sympathetic process used to optimize academic performance, correction of exam stress and protection of students' health

The article is devoted to the influence of an increased level of situational and personal anxiety of examination stress on the indices of the autonomic nervous system in 17-21-year-old male students (I and V courses) with a melancholic type of nervous system. In the course of the conducted studies, it was found that in 17- and 21-year-old students-melancholic during the examination process between heart rate and blood pressure there are some differences that do not normalize after the exam. Vegetative indicators in 21-year-old students in the periods before and after the exam are slightly increased, relative to indicators in 17-year-old students. The Kerdo vegetative index (VIC) in both age groups was in a state of sympathicotonia, which is an indicator of the superiority of the sympathetic nervous system throughout the entire examination process. The results obtained in the course of this study can be used to optimize learning activities, relieve stress in exams and protect students' health.
Background: One of the main negative factors of the educational environment is the increased stress impact on the cardiovascular system of students preparing for examinations. The cumulative effect of a long-term, systematic exposure to stressors may be accompanied by impaired mental and somatic health of students. The extent of response to stress is individual; it is usually determined by cardiovascular health and a complex of psychophysiological characteristics of the body. Objective: To study the main parameters of central hemodynamics in medical students depending on the body mass index and adaptive potential in the pre-examination study period Materials and methods: In spring–summer 2019, 170 medical students (young men and women aged 20.4 ± 0.3 years) with different adaptive potential of the circulatory system were surveyed during a pre-exam study period to establish their anthropometric indicators, blood pressure and heart rate and to further estimate the body mass index and the main central hemodynamics parameters. Results: The average heart rate of students during the pre-exam study period was 85.4 ± 12.21 beats per minute. The level of metabolic and energy processes in the myocardium was characterized as moderate with a tendency to insufficient functional capacity of the cardiovascular system (CI = 90.4 ± 1.22). Significant differences were revealed in a number of parameters un-der study depending on gender, body mass index (F = 3.99; p = 0.00890) and the adaptive potential of the circulatory system (F = 23.08; p = 0.00000). Conclusions: In the pre-examination study period, both the heart rate and the Kerdo index among the students were elevated, which indicates the predominance of sympathetic autonomic stress. The students with tense adaptation mechanisms demonstrated higher values of certain hemodynamic parameters. The pulse pressure and the Robinson index were higher in overweight students compared to their peers with a normal body mass index. None of the students with class 1 obesity had a satisfactory level of adaptation of the circulatory system. The analysis of central hemodynamic parameters enables the assessment of tolerance of the cardiovascular system of students to the burden of learning.
