Resumen

Introducción. En estudios previos se han investigado las pautas nutritivas en sujetos no entrenados; en sujetos entrenados hay menos información.

Objetivos. El objeto de este estudio fue examinar los efectos de un suplemento con carbohidratos y proteínas (CHO+PROT) sobre el rendimiento de levantadores de peso entrenados

Métodos. Diez levantadores entrenados (edad 30,8±5,1, 177.4 ±4.0 cm, 94.3 ± 12.4 kg, tiempo de entrenamiento = 5.3 ± 2.9 años) completaron un programa de doce semanas usando bloques periódicos. Con un diseño doble ciego con placebo se compararon los grupos en series de 2x4; se analizaron los distintos parámetros específicos del deporte. Para la comparación se utilizó ANOVA.

Resultados. No hubo diferencias estadísticamente significativas ( p>0.05)entre grupos tratados y grupos con placebo en cuanto a las medidas de altura de salto y potencia máxima en saltos con peso y sin peso. Tampoco hubo diferencias estadísticamente significativas (p>0.05) en la fuerza máxima ni en el ritmo de desarrollo de la fuerza con levantamientos isométricos de medio muslo.

Conclusión. Estos hallazgos indican que un suplemento de CHO+PROT en comparación con el placebo no aportó beneficios adicionales en levantadores entrenados durante un protocolo de bloques periódicos de 12 semanas.
