INTRODUCTION The performance during the running sector of the cycling-running succession in triathlon has been suggested to be helpful in the detection of talented triathletes, even more important than VO2max (1). Thus, the aim of this study was to compare the cardiorespiratory response during a cycling-running trial of high level triathletes of different age, ir order to establish standards of performance for young triathletes. MATERIAL AND METHODS Six professional triathletes (G1; 23.8 ± 5.6 years; 71.2 ± 8.7 kg; 180.0 ± 8.8 cm) belonging to the Spanish National Triathlon Team and nine elite young triathletes (G2; 15.2±0.8 years; 60.8±6.2 kg; 173.7±6.4 cm), selected by the Spanish Triathlon Federation as the best in their category (under 16), participated in the study. Experimental protocol consisted of two trials performed in ramdon order. In trial 1 (C-R) subjects completed a 30 min cycling at 3.5 W/kg on a cyclergometer. Inmediately after, subjects run 3000m as fast as possible on a 400m track (7.5 laps). Trial 2 (R) consisted of running 3000m as fast as possible. All cardiorespiratory variables were measured with a portable metabolic system (Jaeger Oxycon Mobile) and oxygen costs (OC) was calculated each 400m using the formula of di Prampero (2). A Student t-test for independent samples was used to examine the differences between the two groups of subjects. Significance was set at p<0.05. RESULTS The OC for the G1 subjects was always lower than that for the G2 subjects, but not significantly so; neither were any differences seen between the OC values for the two tests. The G1 subjects took 1.2% longer to complete the running component of the C-R test than to complete the R test (591.2 ± 25.8 vs. 584.6 ± 30.4 s), compared to 3.7% longer for the G2 subjects (669.1 ± 23.8 vs. 645.5 ± 15.8 s). This loss of performance was only significant for the younger subjects DISCUSSION The C-R tests was associated with an acute cardiorespiratory response in the younger athletes (G2) that was not seen in the professionals (G1). This explains the loss of performance seen in these younger competitors in terms of the time to compete the run and the mean speed maintained. It is possible that the G1 subjects had a better adapted cardiorespiratory response given the longer accumulation of specific training over their sporting lives; certainly it has been shown that training in cycling-running blocks improves performance (3, 4). Finally, this study provides a performance profile of elite triathletes for the cycling-running trial and shows that young competitors who want to compete at international level must achieve times of under 600 s in the post-cycling running component under the present C-R test conditions.
