前言多年来国内外普遍在探讨对人体有氧代谢能力的测试方法及理论。在运动过程中,心输出量是冠状血流量和心肌氧需量的决定因素。心率及心脏作功指数与心肌氧需量密切相关;氧耗量与最大心输出量直接相关。人们通常用O_2max、PWC170试验来评价人体的心肺功能及机能状态。人体器官大部分均有较大的储备能力,运动时由于大量肌肉活动,增加了O_2消耗量和CO_2排出量,同时也增加了气体运输和交换的有关机制的负荷,故运动试验可以测 Preface For many years both at home and abroad are generally discussing the testing methods and theories on the aerobic metabolism capacity of the human body. During exercise, cardiac output is a determinant of coronary blood flow and myocardial oxygen demand. Heart rate and cardiac work index are closely related to myocardial oxygen demand; oxygen consumption and maximum cardiac output are directly related. People usually use  O_2max, PWC170 test to evaluate the body’s cardiopulmonary function and functional status. Most human organs have a greater reserve capacity, exercise due to a large number of muscle activity, increased O 2 consumption and CO 2 emissions, but also increased the transport and exchange of gases related to the mechanism of load, so the exercise test can be measured
