Figure 4. OUES100_normalized and V̇O_2peak (mL·min⁻¹·kg⁻¹).

The linear relationship between OUES100_normalized and V̇O_2peak (mL·min⁻¹·kg⁻¹) for participants that did not satisfy criteria (n=21) with the solid linear slope (same as Figure 3) estimated from participants who satisfied criteria (n=85). Figure 4 demonstrates that data points for participants who did not satisfy criteria are located on the right of the solid slope, indicating an underestimation of their V̇O_2peak. On average, these participants had a mean V̇O_2peak underestimation of 2.31 mL·min⁻¹·kg⁻¹ (Table 3).
