Abstract

The observation by Lavoisier and LaPlace in 18th century that muscular contraction consumes oxygen (0,) and produces carbon dioxide (CO,) had made it possible to study the mechanisms of exercise performance in human beings (1). An individual’s capacity to perform increasing levels of dynamic work depends upon the amount of oxygen that can be delivered to working muscles and on the capacity of muscles to oxidize substrates. The structural and physiological integrity of the respiratory, cardiovascular and muscular systems is essential for delivery of oxygen to the tissues and removal of carbon dioxide from the body. Cardio-Pulmonary exercise testing (CPX) is one of the important investigative tools to evaluate patients with dyspnoea or exercise intolerance who have pulmonary or cardiac dysfunctions or both and in the assessment of work impairment. Exercise testing provides clinically useful information that is not available at rest. In addition, CPX is recognized as an useful noninvasive method to evaluate healthy individuals in competitive sports. In order to detect and interpret abnormalities during exercise, it is essential that one should have a knowledge of normal cardio-pulmonary and metabolic responses to exercise.
