Abstract
Burnley, M, Doust, J and Jones, A (2005) Effects of Prior Warm-up Regime on Severe-Intensity Cycling Performance. Medicine and Science in Sports and Exercise, 37 (5). pp. 838-845. ISSN 1530-0315 RAE2008Purpose: The purpose of the present study was to determine the effect of three different warm-up regimes on cycling work output during a 7-min performance trial. Methods: After habituation to the experimental methods, 12 well-trained cyclists completed a series of 7-min performance trials, involving 2 min of constant-work rate exercise at ?90% VO2max and a further 5 min during which subjects attempted to maximize power output. This trial was performed without prior intervention and 10 min after bouts of moderate, heavy, or sprint exercise in a random order. Pulmonary gas exchange was measured breath by breath during all performance trials. Results: At 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 not significantly reduced after sprint exercise (control, 330 ? 42 W; moderate, 338 ? 39 W; heavy, 339 ? 42 W; sprint, 324 ? 45 W). Conclusions: These 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.Peer revieweKeywords
