OPTIMIZATION OF THE ATHLETES’ PSYCHOFUNCTIONAL STATE UNDER MAXIMUM PHYSICAL EXERTION IN HOT CLIMATES WITH ADDITIONAL DEAD SPACE
Physiological and psychophysiological aspects of application of the additional dead space in athletes’ training, allowing to increase the body adaptive capacity to work in a hot climate were studied in this research. It is shown that training with an additional dead space causes essential changes in some body systems. As a result of the ongoing adaptation a number of hemodynamic parameters improve, indicators of the external breathing system considerably increase. Despite the distinct considerable exertion of the body adaptive capacity, significant negative changes in psychophysiological functions, the mental sphere were absent. Moreover, there was an optimization of the CNS functional state and the athletes’ performance remained at high level. Incorporation of breathing with additional dead space into training transfers the body to a new stage of adaptation process, to a more active involvement of higher autonomic centers in the mechanism of adaptation to increased physical activity. It should be assumed that the exercise with additional dead space required the mobilization of the additional functional reserves of the body.
