    Abstract:
    Parameters of ventilation influx, ventilation debt and ventilation demand of exercise were calculated on the basis of heart rate dynamics and parameters of external breathing during the testing procedure and recovery of elite runners during of the maximum workout. It was established that all of external breathing values closely reproduce changes of basic parameters of oxygen demand during the exercises at high intensity and duration and can be used for quantification and valuation of exercise loads in sport. During the conducted at the research it was experimentally proved that high level of sporting achievements in middle and long distance running is defined by three major factors of an aerobic exchange in an organism: 1. General ratio of increase in level of pulmonary ventilation (VE), consumption of oxygen (VO2) and allocation of carbon dioxide (CO2); 2. During the expiration--rate and of supply speed of oxygen (O2) from lungs to working muscles; 3. Rate of oxygenation (StO2) and total speed of the blood-groove.
