Simulated effect of training when only OXPHOS activity is elevated (set A of simulations)

Parameter	Untrained	Trained
OXPHOS activity, kOX	0.8	1.1 (↑37.5%)
(in relation to standard)
Variable
V̇O2max, mM·min−1	10.43	14.61 (↑40.1%)
AUTcrit, unitless	60.6	82.0 (↑35.3%)
t0.63, s	29.2	22.8 (↓21.9%)

The change in the parameter value causes changes in variable values. A_UTcrit, critical ATP usage activity (corresponding to critical power); k_OX, oxidative phosphorylation (OXPHOS) activity; V̇O_2max, maximal V̇O₂; t_0.63, characteristic transition time of the V̇O₂ on-kinetics (analogous to τ_p).
