J Strength Cond Res 24(2): 370-374, 2010-Maximal power production is of primary importance for many sporting events. Therefore, using a test that has been shown to be both valid and reliable will allow for accurate baseline testing, measurement of progress, and evaluation of performance. This study examined peak power (PP) during repeated Wingate trials after no warm-up (NWU), a steady state warm-up, and an interval warm-up. In a randomized placebo-controlled study, 11 subjects (38 ± 8.2 years) performed two 10-second Wingate trials with 4 minutes of recovery between efforts. Warm-up protocols were completed before each Wingate trial and were immediately followed by trial I. Peak power was measured during each trial. Results indicate that PP is not significantly (p > 0.05) different from trial I to trial II for either of the warm-up protocols. The NWU trial II was significantly greater than the NWU trial I (855 ± 230 W > 814 ± 222 W, p < 0.05) when analyzed with a paired samples t-test. Peak power appears to be greatest after a general self-selected warm-up, but not after a previously intense bike warm-up. When testing for maximal power output via the Wingate anaerobic test, one should allow for a familiarization trial and should ensure full recovery between this trial and the baseline evaluation.
