Abstract
Purpose: Although there is clear evidence for the influence of a warming-up (WU) on subsequent exercise, the influence of a WU on the pacing strategy remains unknown. The purpose of this study was to explore the effect of three different WU conditions on the pacing strategy and oxygen consumption (V"02) kinetics over a 4000 meter individual cycling time trial (TI). Methods: Eleven participants performed three 4000 meter TI's on their own road bike, mounted in a Tacx. Each n was preceded by a different WU; 1) no warming-up (NoWU), 2) 35% (WU35) and 3) 70% of the v·o2max (WU70). Pulmonary gas exchange (breath by breath) and power output were measured during then. Results: No difference in pacing strategy was found between the three different WU conditions: F(2, 20) = 1.428, P > 0.05, nor when a separate look at the first 1000 meter (F(2, 20) = 0.044, P > 0.05) or the last 1000 meter (F(2, 20) = 3.193, P > 0.05) of then was taken. v·o2 kinetics did not change in the different WU conditions when they were compared over separate 400 meter segments: F(2, 20) = 0.469, p > 0.05. Conclusion: The current study found no difference in pacing strategy on a 4000m n, when WU preceding the n was executed on different intensities. Neither was a significant difference in the v·o 2 kinetics detected throughout the different WU conditions. Furthermore, no difference in performance was found as a result of the different WU conditions, which might be a reason why no difference in pacing strategy throughout the study was found.
