Аннотация: ADAPTATION OF CARDIOVASCULAR SYSTEM OF ATHLETES TO PHYSICAL LOADS A.I. Zav'yalov, professor, Dr.Hab. Krasnoyarsk state pedagogical university named after V.P. Astaf'ev, Krasnoyarsk S.V. Bizukin, associate professor Siberian federal university, Krasnoyarsk Key words: training of orienteerers, running test, blood minute volume. CardiПоказать полностьюovascular system is one of key factors limiting athlete's exercise performance, directly influencing sports result. Unfortunately, only two directions are subjected in teaching students of sports universities to educational-training activity, analyzing the work of cardiovascular system: 1) registration of electrocardiogram in 12 leads "for further calculation of heart rate at rest, at work and in the period of recovery and 2) registration of arterial pressure at rest and after load to full recovery". registration of electrocardiogram is not to be used only for pulse calculation, as electrocardiogram contains necessary information on the state of myocardium, but for allocation of systolic or stroke volume by arterial pressure, that is the amount of blood excreted by heart to aorta within one contraction, it is unjustified not to estimate blood minute volume. To fill this gap in biopedagogical knowledge the researchers carried out special researches on allocation of informative parameters of cardiovascular system, available for trainers-teachers determining adaptation of athletes' cardiovascular system to physical loads. The studies revealed the correlation of orienteerers' cardiovascular system (in view of age and sportsmanship) at rest and immediately after physical load.
