PURPOSE: Obesity causes lung restriction and often results in exertional dyspnea. Exercise capacity is reduced in obese subjects, possibly due to impairment in ventilation during exercise. Body Mass Index (BMI) affects exercise capacity (VO2max). Whether BMI affects ventilatory parameters during exercise, thereby contributing to dyspnea has not been studied. The objective of this study was to determine the impact of BMI on ventilatory parameters -maximal voluntary ventilation (MVV), ventilation at maximal exercise (VEmax), Breathing reserve (BR), Respiratory rate (RR) and Tidal volume (VT) at peak exercise during Cardiopulmonary Exercise Testing (CPExT).
