In this study, we observed the variations on physiological and perceptual variables during a self-paced 10,000-m race walking event with the aim to trace a preliminary performance profile of the distance. On fourteen male athletes, heart rate was monitored continuously throughout the event. The rating of perceived exertion was collected using the Borg's 6-20 RPE scale placed at each 1000-m of an outdoor-tartan-track. Pacing data were retrieved from the official race results and presented as percent change compared to the first split-time. The athletes spent 95.4% at 90-100% of HRpeak, while the other work (4.6%) was negligible. During the race a shift towards higher HR values were observed because % HRpeak increased by 3.6% in the last versus the first 1000-m sector (P = 0.002, ES = 1.55 ± 0.68, large). The mean RPE reported by the athletes in the last 1000-m was significantly higher than the first five sectors (P < 0.02, ES = 1.93 to 2.96, large to very large). The mean percent change increased between the first six sectors and the last 1000-m sector (P < 0.01, ES = 1.02 to 2.1, moderate to very large). The analysis of walking velocity at each 1000-m sector suggested the adoption of a negative pacing. In conclusion, rating of perceived exertion may be a valid marker of exercise intensity even in real settings. Match physiological and perceptual data with work rate is required to understand the race-related regulatory processes. Pacing should be considered as a conscious behaviour decided by the athletes based on the internal feed-back during the race. |
