Peculiarities of the thoracal respiratory movements under the unconscious inspirator-expirator resistance

We studied the accuracy of the thoracal respiratory movements under the unconscious inspiratory-expirator resistance in a group of young women. The accuracy of the thoracal movements somewhat decreased due to the general deviation. Breathing without the unconscious resistance led to a significant increase in the respiratory volume, both due to the thoracic movements and involuntary abdominal ones, because of an inadequate reproduction of the given effort by the subjects.
