Objective of the study was to identification of significant indicators of variational cardiointervalometry of 400 m runners at the training stage.
Methods and structure of the study. The experiment involved 24 athletes specializing in long sprints, whose age was 16,92 ± 0,72 years, their sports result in the 400 m run was 49,76 ± 0,86 s. We used the diagnostic automated complex «Cardio+» to determine the indicators of variational cardiointervalometry at rest, paired correlation analysis using the licensed IBM SPSS Statistics 22.0 program. The research was carried out on the basis of a sports school in Panjin, China.
Results and conclusions. To monitor the functional state of qualified runners aged 16–18 years, specializing in long sprints, it is advisable to use parameters characterizing the predominance of the type of autonomic regulation, vagal, sympathotonic and humoral-metabolic influences on regulation, as well as the degree of centralization of heart rate control, the activity of the body’s regulatory systems and functional the state of the cardiovascular system as a whole.

Keywords: athletics, long sprint, functional state, correlation analysis.
