Functional variability as efficiency factor in handball throwing to the goal
The purpose of this study was to compare and to gauge players’ intra-individual variability in the movement pattern of four throwing directions, which are the corners of the goal, in the presence of the goalkeeper in handball.

| description | The purpose of this study was to compare and to gauge players’ intra-individual variability in the movement pattern of four throwing directions, which are the corners of the goal, in the presence of the goalkeeper in handball. Twelve right handed players from the Spanish first division participated as subjects of whom five were experienced field players and seven were experienced goalkeepers. The throws were filmed by two video cameras synchronized temporally at 500 Hz, allowing us to obtain the spatial coordinates of a model composed of five markers body are the geometric center of the ball. We used a statistical model based on cluster analysis, and a factorial ANOVA of the temporal data recorded to analyze the differences among the throws. The results show that specialist distance throwers achieve greater variability in their movement pattern, regardless of the changes in the different throwing directions. Non-specialist throwers offer more and earlier direction indicators, before the release of the ball, to goalkeepers than distance throwers. The wrist and the ball were the most sensitive direction indicators of the throws. The transverse axis (y) offered greater amplitude of movement in this axis when the throw is made to the left side of the thrower.
