Change of heart rate variability at foreign students in the midlands

Prenosological assessment of the functional state of students studying in different climatic and geographical conditions is a very important task, since it allows timely detection of conditions that precede pathologies in students and contributes to the preservation of health. Goal. Study of the state of the regulatory mechanisms of the cardiovascular system in foreign students living and studying in the midlands. Materials and methods. The study involved 342 first- and third-year students aged 20.0±1.9 years from India. The survey was carried out in the conditions of the low mountains (760 m above sea level, control group) and the midlands (1650 m above sea level). The main time and spectral parameters of HRV were recorded within 5 minutes using the hardware and software complex Psychophysiologist. Results. The comparative assessment showed that students living in the conditions of the midlands had low values of SDNN, TP, VLF, LF and HF and high indicators of AMo, HR, SI, which indicates the predominance of central regulatory mechanisms and the shift of the vegetative balance towards the sympathetic link in this group. Conclusion. The revealed changes in the spectral and temporal parameters of HRV in midlands students characterize the idea of a regulatory and adaptive state of the body, in which energy and metabolic resources are activated, primarily the circulatory system, aimed at maintaining homeostasis in changing environmental conditions.
