Analysis of the psychophysiological status of first and second year students of a medical university

The calculation of the Baevsky index is based on an analysis of heart rate variability, which provides information on fluctuations in the intervals between heart contractions and forms the basis for assessing the effect of the autonomic nervous system on the functioning of the cardiovascular system as a whole. Purpose of work: Comparative assessment of stress resistance of first and second year medical students. Research materials and methods: The study involved 128 students aged 17 to 23 years VSMU named after N.N. Burdenko. Collected data on physical activity and health status of participants from the Health app. On the psychophysiological testing device of the Psychophysiologist UPFT-1/30, key parameters for assessing stress and adaptation were measured, including the Baevsky index. Study results: The study found that 77.9% of second-year students had a Baevsky index within the normal range, indicating better adaptation to learning stress. Moderate physical activity (5 000–10 000 steps/day) was also found to reduce stress, whereas high activity ( 10 000 steps/day) caused tension in 24.5% of students. Conclusions: The identified statistically based differences in the Baevsky index values between freshmen and sophomores show the growing opportunities for students to adapt to learning stress throughout their studies. Moderate physical activity has a positive effect on the regulation of the functions of the autonomic nervous system and on the level of adaptive capabilities for stress, while extreme levels of physical activity can negatively affect these processes.
