One of the main task of the current medico-biological control is aimed at the timely identification of the dysfunctionality of training overloads, a comprehensive assessment of the athlete's condition, and to establish a feedback, since most of the signs of inconsistency between the load and recovery are subjective by their nature, and may be masked by the problems of the psychological sphere or have general, non-specific manifestations. To find the symptoms during a single examination is far from being sufficient, an important component for a successful diagnosis is the observation of the stability and dynamics in symptoms. The purpose of the study is to investigate the response of cardiovascular system indicators in track and field athletes with different physical performance when performing the PWC170 submaximal test. 71 athletes, divided into two groups, were included in the study. The main group consisted of 30 people whose heart rate and blood pressure response were found as unsatisfactory when performing the standard Letunov test for professional athletes (hereinafter referred to as standard physical exercise). The comparison group included 41 people who demonstrated a satisfactory response. There were 34 women out of all participants, 15 individuals were in the main group and 19 individuals were in the comparison group. The average age of the examinees was 22.49 years, no significant differences in age were found between the two groups. Examinations were carried out in the Centre of Sports Medicine, Sumy State University. Among the athletes, a predominantly hypertensive type of reaction to the exercise test is observed, and the recovery of post-exercise parameters occurs slowly during the second half of the observation time that may evidence the predominance of the activity of the sympathetic tone of the autonomic nervous system. In our opinion, the practical significance of the diagnostic methods, which should be used for assessing the health of athletes, is determined, first of all, by their application in dynamics, in accordance with the changing conditions of the training schedule. Under such conditions, it seems reasonable to select simple and objective methods of testing the response to physical exertion in professional athletes that enables to evaluate their reaction to the load and hemodynamic parameters during and after the exertion of various nature.
