Abstract

During maximal exercise, the gas exchange function of the lung is challenged because of the major cardiopulmonary changes that must occur to meet the increased metabolic demands imposed by exercise. In healthy untrained young adults, the respiratory system is able to meet these demands imposed on it during maximal exercise by implementing several key mechanisms. Nonetheless, there are several exceptional cases in which the lung is unable to accommodate the demands of exercise because of vascular or airway limitations.

摘要

在最大运动期间，由于为满足运动所带来的增加的代谢需求而必须发生的主要心肺变化，肺的气体交换功能受到挑战。在健康的未经训练的年轻成年人中，呼吸系统能够通过实施几种关键机制来满足最大运动期间对其施加的这些需求。尽管如此，仍有一些特殊情况，由于血管或气道限制，肺无法适应运动的需求。
