Effects of Work-matched Moderate- and High-Intensity Warm-up on Power Output During 2-min Supramaximal Cycling
Participants
n=9 active young males
Protocol
120-s supramaximal cycling: 90 s of constant-workload cycling at 110% VO2peak followed by 30 s of maximal cycling (mimics the final sprint of ~2-min events such as the 800-m run, 1500-m speed skating or Keirin)
Preceded by (1) no warm-up, (2) 10-min cycling warm-up at 40% VO2peak (moderate), or (3) 5-min cycling warm-up at 80% VO2peak (high); total work matched between the two warm-ups
Outcomes: 5-s peak power (within the first 10 s of the maximal 30 s) and 30-s mean power in the final sprint; VO2 during the 90-s constant load; post-warm-up blood lactate
Key Results
Both warm-ups increased 5-s peak and 30-s mean power in the final 30-s sprint compared with no warm-up
High- vs moderate-intensity warm-up: greater 5-s peak power (577 ± 169 vs 541 ± 175 W, P = 0.01) but no difference in 30-s mean power (482 ± 109 vs 470 ± 135 W, P = 1.00)
VO2 during the 90-s constant-load phase and post-warm-up blood lactate were both higher after the high-intensity warm-up (all P ≤ 0.05)
Authors' conclusion: work-matched moderate (~40% VO2peak) and high (~80% VO2peak) warm-ups both improve final-sprint (~30 s) performance late in a 120-s supramaximal bout; the high-intensity warm-up adds a further gain only for very short (<10 s) maximal sprinting
Mechanism
Inference (authors' framing): the higher VO2 during the constant-load phase after the harder warm-up indicates a larger oxidative contribution, sparing anaerobic capacity for the sprint's first seconds; the higher pre-exercise lactate did not impair the sprint. Neuromuscular/temperature mechanisms were not measured in the abstract.
Practical Application
In 9 active men, both a 10-min warm-up at 40% VO2peak and a work-matched 5-min warm-up at 80% VO2peak improved the final 30-s sprint of a 2-min supramaximal cycling bout versus no warm-up; the harder, shorter warm-up gave a higher 5-s peak (577 vs 541 W) but the same 30-s mean power (482 vs 470 W) — warm up either way; go harder and shorter only if the very first seconds of the sprint matter
If warm-up time is limited: half the duration at double the intensity delivers the same final-sprint mean power and a better peak
The higher lactate after the hard warm-up was not a handicap for a ~2-min effort
Not from this paper; the base's own practice: for 2-3 min all-out efforts, a ~5-min block at roughly 80% VO2peak (about threshold power) followed by easy spinning is the base's default opener
Limitations
Only a 2-min supramaximal test — not endurance
Work-matched design limits ecological validity

n=10 -> n=9; warm-ups "8 min at 40% / 4 min at 80%" -> 10 min at 40% / 5 min at 80% VO2peak; test "2-min all-out" -> 90 s at 110% VO2peak + 30 s maximal.
"Moderate warm-up → not significant vs no warm-up" -> abstract: BOTH warm-ups improved peak and mean power vs no warm-up; high beat moderate only for 5-s peak (577 vs 541 W), not 30-s mean (P = 1.00).
