[System analysis of the process of oxygen supply in young sportsmen during physical exercise of various intensities].
Young sportsmen were found to have nonhomogeneous and qualitatively different participation of the hemodynamic, respiratory and tissue mechanisms in formation of the oxygen supply system on discretely increasing physical exercises. In maximal exercises, the O2 utilization in tissues is the main limiting section on oxygen consumption. Mathematic formulae are suggested to estimate the volume of blood circulation per minute according to the magnitude of oxygen consumption and respiratory capacity per minute.
