Studied the physiological aspects of the application in the training of athletes additional dead space that would increase the adaptive capacity of the organism to work in a hot climate. It is shown that the training sessions athletes - runners at a high temperature of the medium leads to a deterioration of cerebral hemodynamic parameters. The use of the dosage of hypoxia in the preparation of qualified athletes contributed to the implementation of mechanisms to urgent adaptation to dynamic physical stress. According to research the status of cerebral circulation by rheoencephalography found that training with a gradual increase in the volume of the additional “dead” space in athletes caused significant positive changes of cerebral hemodynamics. It results in an increase of the relative magnitude of pulse blood brain while improving conditions for venous outflow due to a decrease in venous tone, reduced to an optimum level asymmetrical perfusion of the brain hemispheres. Changes in the control group were of opposite nature.
