Purpose. Drafting, performing an activity in a sheltered position behind one or more athletes, is commonly used in team pursuit races in long-track speed skating. This study aims to develop a better understanding of the impact of drafting on physical load (heart rate) and perceived physical load (ratings of perceived exertion (RPE)) per drafting position. Methods. Eighteen skilled skaters (mean age 20.0 ± 4.8 years) skated three trials of five laps in groups of 3 matched based on body size and skating performance, in first, second or third position, with consistent average velocity in seconds per lap. Heart rate and RPE values were measured. Results. Repeated measures ANOVA showed differences between the three positions for heart rate (F2,28 = 28.9, p<0.001, ηp2 = 0.674) and RPE (F1.3,22.1 = 7.02, p<0.05, ηp2 = 0.292). Heart rate was significantly lower when drafting in second (p<0.001, Δ=5.8±4.5 bpm) and third (p<0.001, Δ=8.4±4.9 bpm) position compared to first position. The heart rate of a skater in third position was lower compared to second position (p<0.05, Δ=2.6±3.7 bpm). RPE (Borg CR-10 scale), of skaters in second (p<0.05, Δ=1.2±1.8) or third position (p<0.05, Δ=1.2±1.9) were significantly lower compared to skaters in the first position. RPE when skating in third position was not significantly different from second position (p=1.00, Δ=0.0±0.8). Conclusion. With similar external load, physical load and perceived physical load were highest for the leading position. This information can help coaches in optimizing the skaters’ race strategy by composing the optimal order for individual athletes, making full use of the skaters’ potential.
