Figure 4.

Pulmonary oxygen uptake ($\dot{V}{\mathrm{O}}_2$) responses and best‐fit modeled responses of a representative participant in the unloaded baseline (A; U→S) and elevated baseline (B; M→S) conditions. Vertical dashed black lines represent the onset of each step transition. ${\tau }_{\dot{v}{\mathrm{o}}_2}$ values are displayed for each transition, with the thick gray lines representing the modeled fits. Lines of residuals are displayed at the bottom in gray.
