Abstract	Prior heavy-intensity exercise facilitates the pulmonary oxygen uptake (V̇O2) response during subsequent exercise, such that its kinetics returns towards first-order. To better understand this “priming” phenomenon, we investigated the effect of priming exercise, over a range of intensities, on the V̇O2 response to heavy-intensity cycle ergometry at a work rate of Δ50% [halfway between lactate threshold (LT) and V̇O2max]. Eight subjects performed two consecutive 6-min bouts separated by 6 min at 20 W. The first bout was each of: no warm-up control (CON), sub-lactate threshold (LT) at 80% of LT, and three supra-LT conditions (Δ20%, Δ40%, and Δ60%). The V̇O2 response during the subsequent bout was evaluated using the “effective” time constant (τ′), and the V̇O2 difference between minutes 3 and 6 (ΔV̇O2(6–3)). The goodness-of-fit, indicative of “first-order” kinetics, was determined by the residual profile, and the mean square of errors (MSEr). The heart rate and blood lactate concentration ([La]r) just prior to the second bout were also measured. Compared with CON, τ′ and ΔV̇O2(6–3) were significantly reduced following all supra-LT priming bouts, while the goodness-of-fit was significantly improved following Δ40% exercise. ΔV̇O2(6–3) and [La]r were negatively correlated (P<0.05), unlike HR. In conclusion, prior exercise just above, but not below, LT facilitated the V̇O2 response in a threshold-like manner. Supra-LT priming exercise influenced the V̇O2 response allowing it to return to within as little as 12% from first-order (compared to ~50% in CON). The associated increases in circulating lactate and/or related factors seem to be centrally involved in this phenomenon.
