Christophe Hausswirth, Yann Le Meur, Francois Bieuzen, Jeanick Brisswalter and Thierry Bernard. Pacing strategy during the initial phase of the run in triathlon: influence on overall performance..

- determine the best pacing strategy to adopt during the initial phase of a short distance triathlon run for highly trained triathletes
- Ten highly trained male triathletes
- incremental running test to determine maximal oxygen uptake, a 10-km control run at free pace and three individual time-trial triathlons (1.5-km swimming, 40-km cycling, 10-km running) in a randomised order.
- Swimming and cycling speeds were imposed as identical to the first triathlon performed
- the first run kilometre was done alternatively
- 5% faster (Tri-Run(+5%)),
- 5% slower (Tri-Run(-5%)) and
- 10% slower (Tri-Run(-10%)) than
- the control run (C-Run).
|Tri-Run(+5%)||2,178 +/- 121 s|
|C-Run||2,000 +/- 72 s|
|Tri-Run(-5%)||2,028 +/- 78 s|
|Tri-Run(-10%)||2,087 +/- 88 s|
- Tri-Run(-5%) resulted in a significantly faster overall 10-km performance than Tri-Run(+5%) and Tri-Run(-10%) (p < 0.05)
- No significant difference was observed with C-Run (p > 0.05)
- Tri-Run(+5%) strategy elicited higher values for oxygen uptake, ventilation, heart rate and blood lactate at the end of the first kilometre than the three other conditions.
- The present results showed that the running speed achieved during the cycle-to-run transition is crucial for the improvement of the running phase as a whole.
- Triathletes would benefit to automate a pace 5% slower than their 10-km control running speed as both 5% faster and 10% slower running speeds over the first kilometre involved weaker overall performances.
