Brain, Cardiac Hemodynamics and Cognition During Exercise in Subjects With Various Cardiovascular Profiles

All subjects will underwent a baseline evaluation including a medical history, physical examination with measurement of height and weight, body composition and fasting blood sample. All subjects will performed a cognitive testing at rest and a maximal cardiopulmonary exercise test (CEPT) with gas exchange analysis. During CEPT, cerebral oxygenation (measured by near-infra red spectroscopy) and cardiac hemodynamics responses (impedance cardiography) will be measured continuously.
