Exercise stress
This mode is characterized by heightened (in comparison with a quiescent state) oxygen demand. The grow of exercise stress means any change of external action on a physiologic system, mediated through muscular mechanical work and leading to intensification of metabolism. The speed-up of metabolism process is connected with the increase of organism oxygen demand. For the satisfaction of increased organism needs in oxygen it is necessary to extend its delivery to organs and tissues, it is reached by work intensification of blood circulation system. It leads to the grow of heartbeat frequency, arterial pressure, stroke and minute blood volumes, reduction of peripheral vascular resistance and speed-up of blood flow.

Exercise stress
This mode is modelled by increase of relatively normal value of "oxygen demand" RO2.
In general case this mode is not pathologic, but it can go with other modelling modes, including pathologic.
