Official Title: Effect of Induced Metabolic Alkalosis by Sodium Bicarbonate Administration on the Ventilatory Response to Exercise in Healthy Adults
Brief Summary: An abnormally high V̇E/V̇CO2 response to exercise is a key pathophysiological feature of patients with chronic cardiopulmonary disease that is associated with adverse health outcomes. It follows that any intervention capable of decreasing the V̇E/V̇CO2 response to exercise has the potential to improve clinical and/or patient-reported outcomes. The investigators of this trial will compare the effects of orally administered sodium chloride (4 g, placebo) and sodium bicarbonate (0.3 g/kg of body mass) on ventilation, breathing pattern, dynamic operating lung volume, gas exhange, cardiovascular, metabolic and symptom parameters during symptom-limited, high-intensity, constant-work-rate cycle exercise testing in healthy adults aged 20-40 years.
