COMPARATIVE ANALYSIS OF HEART RATE VARIABILITY AMONG FAR EASTERN FEDERAL UNIVERSITY STUDENTS EXHIBITING VARYING LEVELS OF PHYSICAL CONDITION
Abstract
Aim. This study aims to identify the features of cardiovascular system regulation through heart rate variability (HRV) metrics across individuals exhibiting varying levels of physical condition (LPC). Materials and methods. This study includes a cohort of male FEFU students, aged between 19 and 24 years, stratified into 2 groups: those with above-average LPC (n = 30) and those with average LPC (n = 16). HRV parameters were recorded under resting conditions and during periods of active orthostasis. Results. The findings underscored statistically significant disparities in HRV indicators, both in terms of time-domain and frequency-domain analyses, between the two groups at rest. Notably, subjects with above-average LPC exhibited enhanced parasympathetic activity and superior autonomic regulation, as evidenced by the HRV metrics. Furthermore, the study observed substantial alterations in HRV during active orthostasis within both groups, indicative of a physiological response to the stressor. Nevertheless, the group with average LPC displayed indications of reduced parasympathetic responsiveness, particularly during the К30:15 period. Conclusion. The conclusion drawn from this research highlights the nuanced relationship between cardiovascular system activity and functional optimization in individuals exhibiting varying levels of physical condition. Specifically, males with above-average LPC demonstrated greater efficiency in resource allocation, contrasting with those with average LPC, who exhibited preliminary signs of exhaustion. This underscores the imperative need for proactive lifestyle adjustments among students to bolster their adaptability and resilience.
