Abstract To determine the acute effects of the different abdominal exercise training postures on endothelial function (flowmediated dilatation, FMD), shear rate, blood flow, vascular resistance, heart rate and arterial blood pressure, 48 healthy untrained (inactive) male participants were randomly allocated equally to the crunch training (CR), side crunch training (SC), and leg raise training (LR) groups. All exercise training programs were designed to yield the same period of exercise session which included 16 repetitions per set for 3 sets. The CR group showed increased FMD, shear rate, blood flow, heart rate, systolic and mean arterial blood pressures (all P
