Most healthy people rarely notice difficulty with their breathing either at rest or even during heavy exercise. Yet, muscular exercise makes unique and multifaceted demands on the respiratory system. During dynamic exercise, ventilation rises in proportion to the metabolic demands of the locomotor muscles. The ventilatory response to exercise requires substantial changes in intrathoracic pressure and in the work output and metabolic rate of the respiratory muscles. As a result, the oxygen cost of breathing represents a significant fraction of total oxygen uptake during intense exercise. This article is protected by copyright. All rights reserved.
