Cardiac Output Estimation for Marathon Runners and its Mathematical Model

Abstract

Cardiac output (CO) and stroke volume (SV) are important hemodynamic parameters for evaluation of cardiovascular performance of the subject. Especially non-invasive estimation of CO during sub maximal and maximal work is valuable..

In this paper, one method suitable for athlete CO estimation is described. This approach was used for group of twenty marathon runners.

Mathematical models and measuring results are also presented.
