Key words: Physiological Parameters The current work investigate the basic physiological parameters, meassured in the laboratory conditions and during training in running events of track and fieldathletic. Informativity and usefulness of this indicators in dayly training practice was compared. Analysis allow to sugest using the heart rate, as an informative and integral physiological indicator, exact meassurement of training workload intensity, involve ventilatory threshold as an reliable indicator for intensification of the anaerobic metabolism, using the hart rate threshold as an additional referent indicator for assignment of lactate threshold, corrections of training process with periodically laboratory physiological investigations.
