Abstract

This research aimed to assess the contribution of the autonomic nervous system to the adaptive abilities of students in the process of practical training. We looked at heart rate variability in 44 young men studying construction and finishing work. In compliance with J. Strelau’s theory, the students were divided into two groups by their personality type according to H.J. Eysenck: the more adapted and the less adapted. An increase in sympathetic effects after practical training was noted in both groups; however, these changes were less pronounced in the more adapted students than in those less adapted. For instance, in the more adapted group the standard deviation decreased by 51.7 %, while in the less adapted group, by 68.6 %; the coefficient of variation decreased by 42.8 % and by 69.3 % respectively. The stress index after practical training was 276 in the more adapted students, and 527.9 in those less adapted. The increase in humoral-metabolic regulation mechanisms was greater in the more adapted group than in the less adapted group (the relative power of low-frequency waves increased by 242.1 % in the former and by 137.5 % in the latter). Changes in the tone of the autonomic nervous system after practical training were found in both groups under study. However, in the less adapted students, parameters indicating sympathicotonia and decreased heart rate variability changed to a greater extent.
