Models for Oxygen Consumption and Cardiac Output as Response to Treadmill Exercise

This paper examines procedure for static and dynamic modeling of oxygen consumption (VO2) and cardiac output (CO) as response to cardiopulmonary exercise on a treadmill ergometer. It should be noted that the derivation of the subject dynamic model was more difficult due to the intermittent load caused by the measurement of lactate. The results are presented on athlete (top football player) who has undergone a total of 10 stress tests over 6 years. The work shows the development of parameters and their modeling by static and dynamic models. The resulting models are generally applicable and the presented procedures can of course also be used for modeling of other physiological parameters. Measurements were performed under laboratory conditions which allowed measurable dosing of the speed and slope of the treadmill and well measurable responses on this load.
