Figure 9. Effects of variation of myoglobin concentration in different fiber types on PO₂ histograms.

Fiber PO₂ probability distribution profiles in muscle tissues under A) light intensity exercise; B) moderate intensity exercise; and C) high intensity exercise, for simulation cases of G3S1, G3S5, G4S1 and G4S5. Dotted lines are simulation results for G3 geometry with uniform capillary distribution, solid lines are results for G4 geometry with fiber type-dependent distribution. Black lines are simulation scenarios S1 and red lines are simulations scenarios S5 when C_Mb is fiber-type-dependent while others use uniform values for different fiber types.
