El objetivo principal de la presente investigacion fue conocer las variables, relativas a la recepcion, que actuan como predictoras de la eficacia de la recepcion. Se analizaron 1325 acciones de recepcion, extraidas de un total de 21 equipos participantes en el Campeonato de Espana Masculino de Categoria Juvenil de 2012. La variable dependiente considerada en la investigacion fue la eficacia de la recepcion. Las variables independientes fueron: movimiento del receptor, funcion del receptor, tipo de recepcion, zona de recepcion-profundidad, zona de recepcion-lateralidad. La regresion logistica multinomial realizada mostro que las variables movimiento del receptor, tipo de recepcion y zona de recepcion-lateralidad, actuaron como predictoras de la eficacia de la recepcion. Concretamente, la eficacia de la recepcion aumentaba si el receptor realizaba un desplazamiento previo y conseguia contactar en posicion estatica, y si recibia en el pasillo de zona 6, y a traves de una tecnica de antebrazos o de dedos. Los resultados obtenidos pueden orientar el proceso de entrenamiento de la recepcion del saque en voleibol de categoria juvenil. Abstract. The main objective of this research was to determine the variables, relatives of the reception that act as predictors of the reception efficacy. 1325 serve reception were analyzed, extracted from a total of 21 games played in the championship of Spain in U-19 male volleyball, in 2012. The variable dependent on the study was the reception efficacy. The variables independent from the study were: receiver movement, in-game role of the receiver, type of reception, depth reception zone, laterality reception zone. The multinomial logistic regression performed showed that the variables, receiver movement, type of reception and laterality reception zone predicted the reception efficacy. Specifically the reception efficacy could increase if the receiver takes a previous displacement and contact in static position also the realization of service reception in corridor zone 6 and a through of the forearm pass or overhand pass. These results can serve to guide the training process both in training and in the category of high-level.
