[Respiratory responses to different human movements].

Respiratory responses to different movements and postures become stabilized according to the respiratory-energy demands of the optimal way for task solution. Passive pedalling entails diminishing of electrical activity, the respiratory reactions at that being significantly higher than at resting but lower as compared to active work. With no circumstantial (sporting) stimuli, the increase of respiratory responses to muscular relaxation in the course of pedalling was as significant as the cardiac outflow volume. Maximal and minimal values of the blood pressure did not change. The circumstantial conditioned stimuli enhanced the respiratory responces both at resting and during passive pedalling.
