In modern society, one of the most important health problems is studying the adaptive capabilities of students. However, this problem can be investigated by determining the main regularities of the adaptation process of the students’ body to various factors of the external environment. The purpose of the study. to identify relationships between the adaptation potential of the cardiovascular system and indicators of the body’s statodynamic stability before and after physical exertion in students with different dominant types of autonomic regulation. Material and methods. analysis of scientific and methodological literature, anthropometric methods, empirical methods (rhythmography, stabilometry), method of assessing the adaptation potential of the cardiovascular system (according to R. M. Baevsky), method of express assessment of the functional state of regulatory systems (according to Shlyk N. I.), rowing simulator Concept-2, and methods of mathematical statistics. The study involved 128 students, including girls (n=63) and boys (n=65) aged 17-25, who were studying at the I, III and V courses of the Petro Mohyla Black Sea National University. Results. The research established that students with different dominant types of autonomic regulation have certain differences in correlations between adaptation potential and indicators of statodynamic stability before and after physical exertion. Thus, the greatest number of correlations was observed in students with a moderate predominance of central regulation (type I) and with a pronounced predominance of central regulation (type II). It should be noted that in the representatives of type I, most of the reliably significant correlational dependencies were characterized by an average strength of connection, but some dependencies had a weak connection. However, in type II, reliably significant correlational dependences were characterized by an average strength of connection, but a tendency towards a strong one was observed. In particular, in students with a moderate predominance of autonomous regulation (type III) and with a pronounced predominance of autonomous regulation (type IV), a smaller number of dependencies between the studied indicators were observed. Thus, in students with the III type of vegetative regulation, all reliably significant correlations were characterized by the average strength of the connection. However, in representatives with type IV, most of the reliably significant dependencies were characterized by a strong connection strength, but some dependencies had a medium connection. Conclusions. The obtained data testify to the differences in correlation relationships before and after physical exercise between students with different dominant types of autonomic regulation. In our opinion, these materials can be taken into account when providing students with recommendations for choosing a sports section (within the discipline «Physical Education»).
