Abstract 14275: The Impact of Continuous and Interval Aerobic Exercise on Endothelium, Arterial Wall Properties and Inflammatory Status

Introduction: Chronic aerobic exercise training is associated with favorable long term cardiovascular effects. Hypothesis: We investigated the acute effects of continuous moderate-intensity aerobic exercise (CAE) and high intensity interval aerobic exercise (hIAE) on endothelial function, arterial stiffness and inflammatory status in healthy subjects. Methods: Twenty healthy men (mean aged 22.6±3.3yr) were recruited in this cross-over study. They participated in two exercise sessions: a) CAE: volume at 50% of maximum aerobic work on a cycle ergometer for 30 min and b) hIAE: interval maximum aerobic work on a cycle ergometer for 30 min. Endothelial function was evaluated by flow-mediated dilation (FMD) in the brachial artery. Carotid-femoral pulse wave velocity (cfPWV) and femoral-dorsalis pedis PWV (fdPWV) were measured as indices of central aortic and peripheral arterial stiffness. Intereleukin (IL)-17 levels were measured with ELISA. Measurements were carried out before and immediately after each exerci...
