Why the study?
Does age affect the cardiorespiratory response and performance of elite triathletes during a cycling-running succession?
Does age affect the cardiorespiratory response and performance of elite triathletes during a cycling-running succession?
Senior elite triathletes demonstrate better performance and more adapted cardiorespiratory responses during cycling-running transitions compared to younger highly trained triathletes.
Senior triathletes may show C-R advantages; hypothesis-generating and should not yet change practice or training guidelines.
The aim of the present work was to compare the cardiorespiratory response of two high level groups of triathletes of different age during a simulation of a cycling-running succession. The two groups, G1 (n=6; age 23.8 5.6 years; weight 71.2 8.7 kg; height 180.0 8.8 cm) and G2 (n=9; age 15.2 0.7 years; weight 60.2 6.8 kg; height 173.6 6.4 cm) performed two tests in a random order. Trial 1 (C-R) consisted of 30 min cycling with a load corresponding to the ventilatory threshold previously calculated, followed by a 3000 m run at the highest possible intensity around a 400 m track. Trial 2 (R), consisted of a 3000 m run at the maximum intensity possible only. The G1 subjects took less time to complete the distance (591.2 compared to 669.1 s for the G2 subjects in the C-R setting, and 584.6 vs. 645.5 s in the R setting). In addition, the G1 subjects showed a more adapted cardiorespiratory response than the G2 subjects. In conclusion, the results show a profile in terms of cardiorespiratory response and performance for senior and young triathletes highly trained.
