Question

Quizplus · Accepted Answer

During mild to moderate exercise, the increase in pulmonary ventilation is primarily due to an increase in tidal volume, which is the volume of air moved in and out of the lungs with each breath. Breathing frequency may also increase slightly, but it is not the primary reason for the increase in pulmonary ventilation. Vital capacity and total lung volume may increase with training, but they do not typically change acutely during exercise.
