Introduction: Cardiopulmonary exercise testing (CPX) systems allow for the analysis of exercise integrative physiology involving the pulmonary, cardiovascular, muscular, and cellular oxidative systems. Subsequently, exercise tolerance is determined by pulmonary gas exchange; cardiovascular performance, including the peripheral vascular tree; and skeletal muscle metabolism.Thus, present study was commenced to evaluateimprovement in exercise tolerance after lifestyle modification using Cardiorespiratory Exercise Testing.
