[Antihypoxic effectiveness of alimentary fasting].
The effect of 14-day alimentary fasting on duration of cats stay at the 12-km "altitude" (till a respiratory standstill up to 10 sec) was studied as well as on writing performance of volunteers breathing with nitrogen mixture. The fasting increased the stay duration by more than a factor of 2 under the conditions of acute hypoxia in these functional tests. With subsequent feeding, the acquired resistance to hypoxia disappeared. The main physiological mechanisms responsible for the high antihypoxia efficiency of the alimentary fasting seem to involve a decrease of oxygen consumption in the organism and its delayed release under acute hypoxia.
