| Abstract (English): | High intensity physical exercise favors accumulation of lactate in muscles and bloodstream, leading to impaired muscle function and exercise performance. This study evaluated the effect of citrulline malate (CM) on blood lactate concentration and perception of fatigue after muscular effort in high performance athletes. Seventy-two high-performance athletes who gave written informed consent were randomly assigned to CM3 g/day, CM 6 g/day or placebo for 13 days. Blood lactate measurements were performed every training day. Fatigue was assessed through an auto-administered questionnaire at baseline and after 6 and 13 days. Main criterion was the percentage of blood lactate recovery 30 minutes after training. The mean percentage of lactate recovery 30 minutes after training was 89.3 ± 1.1% in the CM3 and 97.9 ± 1.3% in the CM6 group, becoming significantly greater than placebo at day 5 with CM3 and at day 3 with CM6. Lactate variations were stable or decreased in the 2 active groups, whereas they increased in the placebo group. At day 13, there was no fatigue perceived in 87.8% (CM6), 71.3% (CM3) and 15.9% (placebo) athletes. Citrulline malate enhances lactate and fatigue recovery of high performance endurance athletes, allowing a faster recovery and training adaptation without deletarious effects.

| Abstract (Spanish): | Hacer ejercicio físico con una intensidad alta favorece la acumulación de lactato en los músculos y circulación sanguínea, lo cual afecta a la función muscular y el rendimiento deportivo. Este estudio evaluó el efecto del malato de citrulina (MC) en la concentración de lactato en sangre y la percepción de la fatiga después de un esfuerzo muscular en deportistas de alto rendimiento. A 72 deportistas de alto rendimiento que dieron su consentimiento informado por escrito se les asignó al azar a 3 g/día de MC, 6 g/día de MC o placebo durante 13 días. Las mediciones de lactato en sangre se llevaron a cabo todos los días de entrenamiento. La fatiga se evaluó mediante un cuestionario autoadministrado al inicio del estudio y después de seis y 13 días. El criterio principal fue el porcentaje de recuperación de lactato en sangre 30 minutos después del entrenamiento. El porcentaje medio de recuperación de lactato 30 minutos después del entrenamiento fue 89.3 ± 1.1% en el grupo MC3 y 97.9 ± 1.3% en el grupo MC6, llegando a ser significativamente mayor que el placebo en el día 5 con MC3 y en el día 3 con MC6. Las variaciones de lactato se mantuvieron estables o disminuyeron en los dos grupos activos, mientras que aumentaron en el grupo de placebo. En el día 13, no se percibió fatiga en 87.8% (MC6), 71.3% (MC3) ni en 15.9% (placebo) de los deportistas. El malato de citrulina mejora la recuperación de lactato y la fatiga de los deportistas con un entrenamiento de alta resistencia, lo que permite una recuperación más rápida y una adaptación al entrenamiento sin efectos nocivos.
