肺系统对运动的反应是有据可查的，在其稳态调节方面是相当精确的，在其生理成本方面是高度有效的，并且在其最大储备内运行良好。在这里记录了这些概括的两个例外：1）在VO 2大于4-5 l的短期工作中观察到的动脉低氧血症。min-1; 2）在不同环境条件下长期剧烈运动引起的呼吸急促性换气过度。这些反应的潜在原因和后果进行了讨论，参考所谓的行使“限制”。强调训练状态是肺部限制的一个原因。
The response of the pulmonary system to exercise is well-documented to be quite precise in its homeostatic regulation, highly efficient in terms of its physiologic cost, and operating well within its maximum reserves. Two exceptions to these generalizations are documented here in the highly-trained athlete: 1) the arterial hypoxemia observed in short-term work at a VO2 greater than 4-5 l . min-1, and 2) the tachypneic hyperventilation of long-term, heavy exercise in varying environmental conditions. The potential causes and consequences of these responses are discussed with reference to so-called exercise "limitations". The trained state as a cause of pulmonary limitations is emphasized.
