Methods: Twenty-one divers performed a maximal static apnea in air or during whole-body immersion. Doppler-echocardiography, arterial blood pressure and haemoglobin saturation (SaO2) were obtained at the beginning of, and at 1/3, 2/3 and maximal BH time.
Introduction: The magnitude of the oxygen-sparing effect induced by the diving response in humans is still under debate. We wished to compare cardiovascular changes during maximal breath-holding (BH) in air and during whole-body immersion at the surface in a group of BH divers.
