[Respiratory mechanics during speech at the time of a static physical load]. 1977

M A Tikhonov, and A S Belan

In 12 healthy male test subjects, aged 18--35, respiratory characteristics during talking at rest and when doing static exercises were studied by simultaneous recording of their pneumotachograms, integrated spirograms and transpulmonary intrathoracic pressures. By building pressure-volume curves for lungs and correcting them for transpulmonary pressure, variations in the pressure under the vocal cords when saying a standardized phrase were determined as related to the exercise level. The relationship between the rate and volume parameters of pulmonary ventilation and airway resistance during talking, on the one hand, and the level of exercises, on the other, was established.
