Typological features of students' adaptation to anaerobic exercise

The purpose of the study is to examine the characteristics of autonomic regulation in students during anaerobic physical exercise based on the analysis of heart rate variability and galvanic skin response. Research methods and organization. The study involved male students belonging to the main health group. The load tests used were exercises included in the GTO Complex standards: a 60 m run and pull-ups from a hang on a high bar. Heart rate variability and galvanic skin response indicators were recorded at rest and immediately after the completion of the physical load. To assess the severity of the response of regulatory mechanisms, the reaction index of the stress index was calculated. Research results and conclusions. The performance of anaerobic physical exercise was accompanied by pronounced changes in heart rate variability and galvanic skin response indicators, reflecting activation of the sympathetic division of the autonomic nervous system. Cluster analysis made it possible to identify three types of autonomic response to physical load: parasympathetic, optimal, and hypersympathetic – which differ in the level of autonomous regulation and the degree of functional tension. The obtained results indicate pronounced individual variability of adaptive reactions in students and confirm the potential of the combined use of heart rate variability and electrodermal activity analysis methods for assessing the body's adaptation to physical loads.
