1-D blood flow modelling in a running human body

What is it about?

In this paper an attempt was made to simulate blood flow in a mobile human arterial network, specifically, in a running human subject. In order to simulate the effect of motion, a previously published immobile 1-D model was modified by including an inertial force term into the momentum equation. To calculate inertial force, gait analysis was performed at different levels of speed. Our results show that motion has a significant effect on the amplitudes of the blood pressure and flow rate but the average values are not effected significantly.

Why is it important?

In this paper we have presented a model that can be used to study the effect of motion in mobile arterial networks. Using the method presented above, the applicability of other 1-D models can also be extended from immobile to mobile arterial networks. Specifically, in the case of a running human, we have shown that motion has significantly increased the oscillation amplitude of blood flow parameters but its averaged effect was not significant.
