Figure 5. Model predictions for phenotypes with different mitochondrial densities.

Model predictions of the ΔG_p - J_p relation during post exercise recovery. Results are shown for normally active healthy subjects (A), sedentary subjects (B), athletes (C). Experimental data are indicated by Δ. Model predictions according to the substrate feedback model (model configuration i) are indicated by a red line. Model predictions according to the parallel activation model (model configuration ii) are indicated by a blue line.
