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.
在12名年龄在18至35岁的健康男性受试对象中，通过同步记录他们的呼吸速度描记图、积分呼吸图和跨肺胸内压，研究了静息交谈和进行静态运动时的呼吸特征。通过构建肺部的压力-容积曲线并对其进行跨肺压校正，确定了在说出标准化短语时声带下方压力的变化与运动水平的关系。一方面建立了交谈期间肺通气的速率和容积参数与气道阻力之间的关系，另一方面建立了与运动水平之间的关系。
