Figure 1.

Relative running economy VO₂ (mL/kg/min) at individual anaerobic threshold (IAT) velocity at 5, 10 and 15 min (i.e., VO₂ averaged across 4–5, 9–10, and 14–15 min at IAT). Ṩ = small to moderate effect size; ṨṨ = large effect size. No statistically significant differences found between conditions.
