Key result
Simulated exercise conditions in an in vitro model approximately doubled forward velocities and greatly reduced flow reversal compared with resting conditions.
Why the study?
Do simulated exercise and postprandial conditions alter pulsatile axial velocity profiles in an in vitro model of the human abdominal aorta compared to resting conditions?

Model findings on exercise hemodynamics are hypothesis-generating; should not change practice pending in vivo studies.
Do simulated exercise and postprandial conditions alter pulsatile axial velocity profiles in an in vitro model of the human abdominal aorta compared to resting conditions?
Simulated exercise and postprandial conditions significantly alter abdominal aortic hemodynamics in an in vitro model, which may influence the progression of atherosclerosis.
Moore et al. (1994) studied Hemodynamics of the abdominal aorta. Simulated exercise and postprandial conditions vs. Resting conditions was evaluated on Pulsatile axial velocity profiles. Simulated exercise conditions in an in vitro model approximately doubled forward velocities and greatly reduced flow reversal compared with resting conditions.
