The theoretical and experimental blood lactate concentration C in mmol/L as a function of time t in seconds when running with poles at the angle of inclination of 0.105 radians. The eight symbols from below are experimental values from the different tests v_1-8. The straight curves represent results from a one-compartment model by Moxnes and Hausken [2], whereas the three stapled curves represent results from the two compartment model by Moxnes and Sandbakk [25] for v₅, v₆ and v₈. Lines from below: black =$v_1=2.08\text{m}/\text{s},{\overline{Q}}_{\mathit{vir}}=0.59Q_{\mathit{max}}$, orange =$v_2=2.33\text{m}/\text{s},{\overline{Q}}_{\mathit{vir}}=0.66Q_{\mathit{max}}$, cyan =$v_3=2.64\text{m}/\text{s},{\overline{Q}}_{\mathit{vir}}=0.74Q_{\mathit{max}}$, red =$v_4=2.83\text{m}/\text{s},{\overline{Q}}_{\mathit{vir}}=0.80Q_{\mathit{max}}$, blue =$v_5=3.08\text{m}/\text{s},{\overline{Q}}_{\mathit{vir}}=0.87Q_{\mathit{max}}$ until a recovery phase starts at t = 800s with v = 1.67m/s, ${\overline{Q}}_{\mathit{vir}}=0.47Q_{\mathit{max}}$, green =$v_6=3.19\text{m}/\text{s},{\overline{Q}}_{\mathit{vir}}=0.90Q_{\mathit{max}}$, yellow =$v_7=3.33\text{m}/\text{s},{\overline{Q}}_{\mathit{vir}}=0.94Q_{\mathit{max}}$, pink =$v_8=3.88\text{m}/\text{s},{\overline{Q}}_{\mathit{vir}}=1.09Q_{\mathit{max}}$.$\text{LT}=0.88Q_{\mathit{max.}}$
