ABSTRACT

Las exigencias físicas de ciertos tipos de deporte y pautas de entrenamiento plantean la necesidad de recurrir al uso de suplementos nutricionales que garanticen un adecuado recambio de aquellas sustancias sometidas a una alta tasa catabólica. El β-hidroxi -β-metilbutarato (HMB) ha demostrado poseer un efecto ergogénico sobre el rendimiento deportivo y prácticamente ningún efecto perjudicial sobre la salud del atleta. La suplementación con HMB pretende, en su aplicación más práctica y conociendo su poder anticatabólico, ayudar al deportista de alto nivel o al deportista poco entrenado a recuperar después de un ejercicio estresante obteniendo un grado de recuperación óptimo para emprender nuevas sesiones de actividad física y/o deportiva específica con el menor daño acumulado en su organismo (AU)


Most of the sport modalities and current training patterns demand high physiological, psycological, tecnical and tactical qualities from the athletes. There is a need for an optimal turnover of those substances with high catabolic rate. Several nutritional ergogenic aids can contribute to optimize these processes. In this sense, β-hydroxi- β-methylbutarate (HMB) has been proposed to have an ergogenic effect on athletic performance without having practically any adverse effect on the athlete’s health. This article reviews the literature about HMB in regard to mechanisms of action, effects on trained and non-trained subjects, optimal dose, and future research. In both highly-and low-trained subjects, HMB supplementation seems to contribute to a better recovery after hard training. This effect can contribute to decrease the accumulative effect on muscle damage caused by daily training sessions (AU)
