El presente trabajo tiene como objetivo analizar los valores de la velocidad y de la precisión en el lanzamiento de siete metros en balonmano con jóvenes jugadores en función de la distribución de la práctica. En este estudio han participado dos grupos de diez jugadores de balonmano de categoría infantil (12,5 años, SD=0,9). Cada uno de estos dos grupos ha sido sometido a dos condiciones de práctica diferente (práctica concentrada y distribuida), en tres series de lanzamientos. Los resultados han mostrado que el grupo con una mayor concentración de la práctica lanza con menor precisión la segunda que la primera serie (F1,9 = 7.92; p<0.05). El grupo con mayor distribución de la práctica es significativamente más preciso (F1,18 = 7.18; p<0.05). Respecto a la velocidad del lanzamiento, el grupo que ha sido sometido a práctica concentrada presenta diferencias significativas mostrando un descenso de velocidad en los lanzamientos a partir de la primera serie.
Palabra clave: distribución de la práctica, velocidad, precisión, balonmano.
Abstract: This study analyzes the effect of the practice distribution in the precision and speed of handball shots performed by young players. Two groups of ten participants were involved in the study (12.5 ± 0.9 years old), with different practice conditions. One group participated under massed practice and the other one under a distributed practice, both in a three series of shots. A within-group analysis showed that the group of mass practice was less accurate in the second series than the previous one (F1, 9 = 7.92, p <0.05). A between-groups analysis showed that the group of distribution practice was more accurate in the third series of shots (F1, 18 = 7.18, p <0.05). Regarding to the shot’s speed, there are differences for the massed practice group showing slower shots after series one.
Key words: distribution of practice, speed, accuracy, handball.
