    Objetivo: Analizar la influencia de diferentes intensidades de nado en los sectores de ciclismo y carrera a pie y en el rendimiento final del triatlón sprint. Métodos: Siete triatletas sub23 y Absolutos (altura de 1,74 ± 0,04 m, peso de 70,82 ± 6,76 kg, edad de 23,42 ± 3,25 años, VO2 max de 63,54 ± 5,23 ml·kg-1·min-1) participaron en este estudio. Realizaron tres triatlones completos a intensidades de nado diferentes (70%, 80% y 90% de un test de 750m previo). Se midió la frecuencia cardíaca y el lactato al finalizar cada sector y el triatlón completo. Resultados: La intensidad de nado del 90% obtuvo el mejor rendimiento final. El lactato y frecuencia cardíaca en el sector de nado para esta condición incrementó significativamente, sin diferencias en los sectores siguientes. Conclusiones: Basándonos en la muestra estudiada, el rendimiento final en un triatlón sprint parece estar condicionado por la intensidad de nado, siendo el 90% la mejor intensidad observada en triatletas moderadamente entrenados.

    Objective: To analyze the influence of different swimming intensities on the subsequent cycling and running sectors and overall sprint triathlon performance. Methods: Seven sub23 and senior triathletes (height 1.74 ± 0.04 m, weight 70.82 ± 6.76 kg, age 23.42 ± 3.25 years, VO2 max 63.54 ± 5.23 ml • kg-1 • min-1) participated in this study. They carried out three complete triathlons at different swimming intensities (70%, 80% and 90% of a previous 750m test). Heart rate and lactate were measured at the end of each sector and after completing the whole triathlon. Results: The 90% swimming intensity obtained the best final performance. Lactate and heart rate in the swimming sector for this condition increased significantly, without differences in the following sectors. Conclusions: Based on the sample studied, the final performance in a sprint triathlon seems to be conditioned by the swim intensity, being 90% the best intensity observed in moderately trained triathletes.
