Abstract:
The article presents the results of survey of two groups of male students (mean age 20 ± 2) from the Department
of Physical Culture and Sports as well as the biology and geography departments. The heart rate variability
was examined using a computerized complex «Varikard» (Russia). Estimation of heart rate variability
was performed using mathematical statistics method of R.M.Baevsky. Cardiovascular system’s fitness was
estimated by determining the type of response to the diving reflex using the method of cold-hypoxiahypercanic
effect (CHE). There was a substantial stress and strain of regulatory systems at the majority of
students of the Faculty of Physical Education and Sport, what shows a decline of adaptive reserves of the
body, caused by excessive loads.
