Assessment of physical activity of the human body by consideration of the thermodynamic system
Original language description
The precise measurement of physical activity - which is the basis of a vital and healthy life - is rather empirical resulting in limited individual and custom activity recommendations. Certainly, very accurate 3D-models of the cardiovascular system exist, however, requiring the numeric solution of the exact Navier-Stokes equations of the flow in blood vessels. These models are suitable e.g. for the research of cardiac diseases, but computationally very expensive. Direct measurements are expensive and often not applicable outside laboratories. This paper offers a new approach to assess physical activity using thermodynamical systems and its leading quantity of entropy which is a compromise between computation time and precise prediction of pressure, volume and flow variables in blood vessels. Based on a simplified (1D) model of the cardiovascular system of the human body we develop and evaluate a setup calculating entropy to determine the intensity of human physical activity in a more precise way than previous parameters, e.g. frequently used energy considerations. The knowledge resulting from the precise real-time physical activity provides the basis for an intelligent human-technology interaction allowing to steadily adjust the degree of physical activity according to the actual individual performance level and thus to improve training and activity recommendations.
