In this short review, the frame of current understandings concerning what determines the upper limit of oxygen flow from the ambient air to the muscu-lar mitochondria during maximal dynamic exercise in humans (i.e., VO2max), was summarized mainly from its modeling perspective. Several models and experirnental evidences which appeared repeatedly in the recent debates regarding the factors limiting V02max, were adopted and criticized. In conclusion, V02max is determined in particular by the integrated interaction between the diffusive and convective factors both to lung 02-loading and muscular 02-unloading in the path-way for 02 flow, although all experimental observations cannot be satisfactorily explained at the present time.
