Diagram of Mean Response Time Calculation. (A) (upper panel) shows V̇O2 during incremental and constant exercise load in a sample case. Rest, warm-up, and a ramp protocol of 10W/min (Ramp10) on day 1 was followed on day 2 by constant load exercise for a total of 25min. (B) (lower panel) shows a diagram of the MRT calculation. The difference in oxygen uptake from VAT on day 1 to V̇O2 steady state (20–25min) on day 2 was defined as ΔV̇O2 ①(ΔV̇O2 after VAT). The difference in oxygen uptake from the day 1 VAT to the earlier MRT was defined as ΔV̇O2 ② (ΔV̇O2 before VAT). VAT – ventilatory anaerobic threshold; V̇O2 – oxygen uptake
