[Characteristics of temporal and spatial parameters of voluntary (set) human respiratory movements under conditions of chemorecptor stimulation of different character].

Dynamics of temporal and spacial parameters of set respiratory movements (in comparison with the movements of the hand) under conditions of progressive hypoxia, hypercapnia, hypoxic-hypercapnic interaction was investigated in 10 men aged from 19 to 30 years. Hypercapnia (especially in combination with hypoxia) is a specific factor preventing voluntary control of the respiratory movements. The certitude (exaggeration of the set respiratory volume) and the capacity to correction of the respiratory movements are mostly influenced by these factors. These facts are considered to be the result of chemoceptor stimulation of the respiratory center (imperative stimulus).
