INTRODUCTION The cycling-running succession has an important physiological component: it is difficult to adapt to running after cycling. Hence, triathletes who show the best overall performance are therefore those in whom the cycling component least affects their running (1). The aim of this study was to compare the changes along two seasons of the cardiorrespiratory response and performance during a cycling-running succession in elite young triathletes. MATERIAL AND METHODS Nine elite young triathletes selected by the Spanish Triathlon Federation as the best in their category (under 16) participated in the study. Experimental protocol was repeated in the same moment of two different seasons (2006 and 2007) and consisted of two trials performed in ramdon order. In trial 1 (C-R) subjects completed 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 cost of running (OC) was calculated each 400m using the formula of di Prampero (2). To asses the differences between C-R and R, and between seasons, paired t-tests were performed and the significant level was fixed at p<0.05. RESULTS The C-R trial was associated with: 1) an acute cardiorespiratory response compared with R and, 2) an impairment of 3.5% in performance during running (647.0 ± 22.9 vs. 624.9 ± 15.0 seconds for C-R and R respectively). When seasons were compared, cardiorrespiratory response and OC were similar, but performance improves significantly in both conditions. Thus, time to complete the running sector decreased a 6.4% during C-R (667.3±24,7 vs. 624.8±21.9 seconds) and 6.3% during R (643.7±15.9 vs. 604.3±14.2 seconds). The mean running speed increased 5.8% during C-R (16.4±0.6 vs. 17.3±0.7 km/h) and 6.4% during R (16.8±0.4 vs. 17.8±0.4 km/h) from 2006 to 2007 season. DISCUSSION Our study confirms the specific cardiorrespiratory response and the loss of performance showed by others during cycling-runnig trial (1, 3, 4), but in our knowledge, this is the first work that evaluate the changes along a season. Millet and coworkers indicated that performance in the running sector might be more important than the VO2max in the detection of talented competitors, and suggested this performance be monitored over time (5). Thus, we conclude that monitoring and comparing this performance with professional could be be helpful in the detection of talented triathletes. References. 1. Hue, O, et al.
