ResumoIntroduction – The aim of this study was to analyze the validity of the critical speed (CS) to determine the speed corresponding to 4 mmol l–1 of blood lactate (S4) and the speed in a 30 min test (S30min) of swimmers aged 10–15 years. Synthesis of facts – CS, S4 and S30min were determined in 12 swimmers (eight boys and four girls) divided into two groups: 10–12 years and 13–15 years. Conclusion – CS was a good predictor of aerobic performance (S30min) independent of the chronological age, providing practical information about the aerobic performance state of young swimmers. Introduction – L’objectif de cette étude est d'analyser la validité de la vitesse critique (VC) pour déterminer la vitesse correspondant à 4 mmol.l–1 de lactate sanguin (V4) et la vitesse dans un essai de 30 min (V30min) chez des nageurs âgés de 10 à 15 ans. Synthèses des faits – VC, V4 et V30min ont été déterminées chez 12 nageurs (8 garçons et 4 filles) divisés en deux groupes: 10–12 ans et 13–15 ans. Conclusion – La vitesse critique est un bon indicateur de la performance aérobie (S30min), indépendant de l'âge chronologique et fournit des informations pratiques sur l'état de performance aérobie de jeunes nageurs.
