  1. Values for all investigated parameters at rest and exercise. Comparison of rest to exercise was tested for significance using an unpaired two-tailed t-test. Aortic arch [arch]; ascending aorta (AAo); descending aorta (DAo); pressure gradient (ΔP); Reynolds number in descending aorta (ReDAo); wall shear stress (WSS)
