Pulmonary gas exchange was measured breath-by-breath during all performance trials.RESULTSAt the onset of the performance trial, baseline blood [lactate] was significantly elevated after heavy and sprint, but not moderate exercise (mean (SD): control, 1.0 (0.3) mM; moderate, 1.0 (0.2) mM; heavy, 3.0 (1.1) mM; sprint, 5.9 (1.5) mM). All three interventions significantly increased the amplitude of the primary VO2 response (control, 2.59 (0.28) L·min−1; moderate, 2.69 (0.27) L·min−1; heavy, 2.78 (0.26) L·min−1; sprint 2.78 (0.30) L·min−1). Mean power output was significantly increased by prior moderate and heavy exercise, but slightly reduced after sprint exercise (control, 330 (42) W; moderate, 338 (39) W; heavy, 339 (42) W; sprint, 324 (45) W).CONCLUSIONSThese data indicate that priming exercise performed in the moderate and heavy intensity domains can improve severe intensity cycling performance by ∼2–3%, the latter condition doing so despite a mild lactacidosis being present at exercise onset.Effects Of Prior Warm‐up Regime On Severe Intensity Cycling Performance: 437 Board #28 3:30 PM ‐ 5:00 PMBurnley, Mark; Doust, Jonathan H.; Jones, Andrew M.
