Abstract

Maximally working skeletal muscle exhibits one of the highest O 2 consumption rates observed in any tissue. In order to understand the mechanisms which bring about these enormous oxygen fluxes, two key questions have to be addressed:
  1. 1.

    How can diffusional fluxes of that magnitude from the red blood cell into the muscle fiber be achieved in spite of unfavourably long diffusion paths?

     
  2. 2.

    How is it possible that red cell transit times through the capillary bed are sufficiently long to discharge enough oxygen even though blood flow values are 25-fold compared to rest and the capillary bed is significantly de-recruited due to raised tissue pressures.
