CHANGE OF PARAMETERS OF CARDIO-VASCULAR SYSTEM OF MIDDLE-DISTANCE RUNNERS AT PRE-COMPETITION STAGE
On the basis of the method of “Cardiointervalmetry” the changes of the parameters of heart rate variability (HRV) of middle-distance runners at the pre-competition stage are presented. The direction of the changes of these parameters is concretized; the relative and absolute values of the parameters are analyzed. The possibility of using the hardware-software complex “Varicard” at the middle-distance runners' pre-competition stage is presented. This complex is used to assess functional changes in the body of a sportsman in response to the proposed load. Finally, the given results can be an informative guideline for possible correction of the training loads for sportsmen.
