“…Нині значно зросли хронічні захворювання серед студентської молоді [1,2]. Високі функціональні резерви мають лише 15-35% студентів [3]. Це пояснюється тим, що сучасне життя характеризується надзвичайно складними екологічними, соціально-еконо-мічними, психологічними умовами.…”

One of the most common diseases in the whole world is obesity. Every year, 18-20 thousand new cases of obesity are recorded in Ukraine. Also, the number of obese students during their studies in institutions of higher education is rapidly increasing, for whom the first year of study is the most difficult and problematic. It is known that even under normal conditions, excessive body weight requires increased energy supply and persons with insufficient weight suffer from a lack of reserves. Therefore, the purpose of our work was to study the features of the state of neurodynamic functions and regulatory processes of the heart based on indicators of heart rate variability in female students with different body weights during the first year of study at a higher education institution. This will be important for the development of individual disease prevention measures for this category of students. The study examined full-time female students (17-18 years old) of the Faculty of Natural Geography Education and Ecology of National Pedagogical Dragomanov University, who were divided into groups according to body mass index: normal, overweight, and underweight. The study was conducted on days of high mental performance under standard conditions in six stages. An electrocardiogram was registered, rhythmograms and variation pulsometry indicators were calculated, and the functional state of the central nervous system was studied using computer methods. According to the Kruskal-Wallis and ANOVA tests, the following indicators were most sensitive to the influence of body weight: moda, moda amplitude, stress index, autonomic balance index, and heart rate. According to Spearman’s non-parametric correlation analysis, at each stage of the examination, correlations between variation characteristics of heart rate variability and indicators of the state of the central nervous system were revealed, and their nature was clarified. It was established that the nature of the correlations in the studied groups was different. Thus, it was established that the deviation of body weight from the norm affects the regulatory processes of the heart and neurodynamic functions during the first year of study. Overweight and underweight female students during the first year of study had a significantly higher intension of regulatory mechanisms compared to female students with a normal body weight, so they can be classified as a group at risk of developing psychosomatic diseases.

The high level of mental and physical training loads on the body of students requires a good development of adaptive-compensatory mechanisms, stress resistance, psychological endurance. On the other hand, modern research indicates the low level of health of students and their maladaptation to high levels of stress, which determines the relevance of the study of changes in the functioning of the cardiovascular system to develop measures to correct adverse conditions and improve physical and mental health. The purpose of the work was to determine the features of changes in heart rate variability of students under the influence of mental and physical activity, taking into account gender characteristics. Material and methods. The article presents the results of a study of heart rate variability of 128 students (65 male and 63 female) of the Petro Mohyla Black Sea National University aged 17-25 years. All students had indicators of variability of resting heart rate, after mental and physical activity on short recordings of the cardio signal (2 minutes), obtained with the help of rhythm "MPFI rhythmograph-1" and EasyHRV software (LLC "ASTER-IT", Kharkiv). We used the proofreading method by Kryvonosov M. V. et al. (2001), which consisted of finding and selecting a specific letter in test tables for 20-25 minutes. Aerobic exercise consisted of running a distance of 2000 m on a rowing machine Concept-2 for 10 minutes. The research results were processed using descriptive statistics and non-parametric criteria. Results and discussion. The results of research showed that at rest almost all statistical and temporal indicators of heart rate variability of boys and girls were within the age norms. Mental load did not lead to a significant deterioration of the indicators studied, which indicated the stereotype of reaction. Exercises led to a significant deterioration in the cardiovascular system of students, as evidenced by a significant decrease relative to the lower limit of the norm of SDNN and RMSSD (almost four times); increase in the index of autonomic balance (above the upper limit of the norm by 90% for boys and 71% for girls); exceeding the upper limit of the norm twice with the indicators of vegetative rhythm and regulatory processes adequacy; an increase in the stress index of boys by 7 times and more than 5 times for girls, which led to exceeding the upper limit of the norm by more than 4-5 times; reduction of the total power of the cardio signal spectrum in boys by 9 times, and by 8 times in girls; power of the spectrum of very low frequencies twice, low frequencies by 5-8 times, high frequencies by 6-11 times. Conclusion. Low energy spectral parameters, as well as reducing the variability of cardio intervals and increasing the stress index are manifestations of hyperadaptive response to exercise and indicate low adaptive capacity of students, which requires the introduction of rehabilitation activities
