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.
根据任务解决的最佳方式的呼吸能量需求，对不同运动和姿势的呼吸反应会趋于稳定。被动蹬车会使电活动减少，此时的呼吸反应明显高于静息时，但与主动运动相比则较低。在没有环境（运动）刺激的情况下，蹬车过程中对肌肉放松的呼吸反应增加与心输出量增加一样显著。血压的最大值和最小值没有变化。环境条件刺激在静息时和被动蹬车期间均增强了呼吸反应。
