Effects of Prior Warm-up Regime on Severe-Intensity Cycling Performance
Participants
n=12 well-trained cyclists
Protocol
7-min performance trial: 2 min constant work rate at ~90% VO2max, then 5 min in which subjects maximised power output
Performed with no prior intervention (control) and 10 min after bouts of moderate, heavy or sprint exercise, in random order
Pulmonary gas exchange breath-by-breath; blood lactate at trial onset
Full text; not checked against the abstract: the sprint bout was repeated all-out sprints (3 × 30 s)
Key Results
| Condition | Baseline lactate at trial onset | Primary VO2 amplitude | Mean power, 7-min trial |
|---|---|---|---|
| Control | 1.0 ± 0.3 mM | 2.59 ± 0.28 L/min | 330 ± 42 W |
| Moderate priming | 1.0 ± 0.2 mM | 2.69 ± 0.27 L/min | 338 ± 39 W (significant increase) |
| Heavy priming | 3.0 ± 1.1 mM (elevated) | 2.78 ± 0.26 L/min | 339 ± 42 W (significant increase) |
| Sprint priming | 5.9 ± 1.5 mM (elevated) | 2.78 ± 0.30 L/min | 324 ± 45 W (not significantly reduced) |
Moderate and heavy priming raised mean power by ~2-3%; the two were equivalent (338 vs 339 W)
Sprint priming did not help (324 W, a non-significant reduction) and left the highest starting lactate
All three interventions increased the amplitude of the primary VO2 response
Heavy priming improved performance despite a mild lactacidosis (3.0 mM) at exercise onset
Mechanism
Authors' framing: priming increases the amplitude of the primary VO2 response, i.e. more of the oxygen demand is met aerobically from the start of the severe effort. Inference, not tested here: greater muscle blood flow / O2 availability at onset and a smaller O2 deficit leave more anaerobic capacity for the maximal phase.
Practical Application
In n=12 well-trained cyclists, a moderate- or heavy-intensity priming bout finished 10 min before a 7-min severe-intensity trial raised mean power by ~2-3% (330 → 338 and 339 W); repeated all-out sprints did not (324 W) and started the trial at 5.9 mM lactate — prime below critical power, not with sprints.
Before a hard interval session or a short race, finish a moderate or heavy (below-CP) priming bout about 10 min before the start; the two intensities were equally effective here, so the heavier one buys nothing extra and starts the effort with 3× the lactate.
Avoid multiple all-out sprints as the final warm-up element — no benefit and a trend to lower power.
Recovery interval as tested: 10 min between priming and the effort; other gaps were not tested.
The outcome is a 7-min severe-intensity trial; the transfer to a long endurance event, where the start is not severe, is not tested here.
Limitations
Lab-based (not field conditions)
7-min performance test ≠ longer race simulation
One recovery interval (10 min); one bout of each priming intensity

"Heavy priming = best trade-off" -> moderate and heavy were equivalent (338 vs 339 W vs 330 W control); heavy also raised starting lactate to 3.0 mM.
Practical "2×2 min at 105% FTP" (a severe-domain bout) and "5-10 min recovery", plus the "280-290 W" pre-race template -> replaced with a moderate or heavy (below-CP) bout 10 min before, as tested; house template removed.
Sport "cycling, sprint" -> cycling. Abstract values (lactate, VO2 amplitude, power) added; "3×30 s" sprint detail marked full text.
