We examined the efficacy of ankle bathing versus aerobic exercise to improve vascular function in young adults whom were randomized to aerobic exercise (AE) (n=13, 40-60% of heart rate reserve), ankle bathing (AB) (n=15, 43℃), or a control condition (CON) (n=14, ankle bathing at 36℃) for 40 min. Conduit vessel function [brachial artery flow-mediated dilation (FMD)], carotid and femoral artery blood flow and shear rate (SR), and arterial stiffness [carotid-to-femoral pulse wave velocity (cf-PWV), augmentation index (AIx@75), β -stiffness index, and arterial compliance] were evaluated. Compared with CON, AE and AB increased percent FMD at 30 min and 90 min (interaction: p<0.05); AB decreased carotid artery blood flow and SR at 30 min, while both AE and AB increased femoral artery blood flow and SR at 30 min and 90 min (interaction: p<0.05); AE and AB decreased cf-PWV and AIx@75 at 30 min and 90 min (interaction: p<0.05); and AE improved both carotid and femoral β-stiffness index and arterial compliance, while AB reduced β-stiffness index and increased arterial compliance only in the femoral artery (interaction: p<0.05). These findings suggest ankle bathing may serve as an alternative strategy for enhancing vascular function.
