Key result
Mathematical and circuit models successfully describe VO2, CO, and HR responses to CPET in two athletes.
Why the study?
The study investigated a non-invasive procedure for static and dynamic modeling of cardiac output and oxygen consumption in response to cardiopulmonary exercise.
Observational (n=2)
No
Mathematical and circuit models can effectively simulate the static and dynamic responses of oxygen consumption, cardiac output, and heart rate to exercise loads during cardiopulmonary exercise testing.
Should not yet influence clinical decisions; leaves open broader validation in exercise physiology.
In this paper, we investigate a non-invasive procedure for static and dynamic modeling of cardiac output and oxygen consumption in response to cardiopulmonary exercise during exercise. The results are presented on 2 athletes - a football player and cross-country runners who have undergone 10 stress tests for 5 years. The results can also be used to model some other physiological parameters. Measurements were performed in laboratory conditions that allowed measurable exercise settings and well-measurable load responses, such as heart rate, ventilation, and oxygen consumption.

Štork et al. (2021) conducted an observational in Healthy athletes (n=2). Cardiopulmonary exercise testing (CPET) was evaluated on Derivation of static and dynamic mathematical models for VO2, CO, and HR. Mathematical and circuit models successfully described the static and dynamic responses of oxygen consumption, cardiac output, and heart rate to cardiopulmonary exercise testing in two athletes.
