The 3-min all-out cycling test (3MT) elicits valuable fitness metrics including V̇O2peak, HRmax, Critical Power (CP), and Work Above End Power (WEP; equivalent to work prime; W’). Twelve (n = 12) healthy active males were recruited to participate in the current study on the effects of the implementation of a race timer on the 3MT. Participants completed a V̇O2peak test and one 3MT familiarization trial before completing one standard 3MT and one 3MT with the presence of a countdown race timer in a randomized order. CP was found to be significantly higher in the timer condition, while WEP was found to be significantly lower (CP: P = .011, WEP: P = 0.004). There were no significant differences in PPO or total work between trials. These results indicate that the presence of a race timer led to a difference in work profiles between tests. Potential explanations for these results may be attributed to the influence of knowledge of time on anticipation, decision-making, and pacing strategy during all-out exercise. The presence of a timer during the test may confer potential differences in performance outcomes in the 3MT.
