Abstract Resume

Background:The throw in handball is influenced by the goalkeeper presence affecting the motor action, the ball speed and accuracy of shot. Specifically in 7-meters throw, it has
recently been shown that the accuracy tends to decrease with the goalkeeper presence and when it is positioned on the goal line. The accuracy and an important factor for the throw performance and it
is expected that the presence and position of the goalkeeper may also influence negatively the efficacy in 7-meters throw. Therefore, the aim of this study was to analyze the influence of the
goalkeeper position on the 7-meters throw efficacy in handball
Methods:Adult handball players (n = 10) of the regional level in São Paulo state, was part in these study. Each volunteer performed 36 attempt of 7-meters throws, in three different
situations: without goalkeeper; with the goalkeeper in the goal line; and the advanced goalkeeper (2 m in front of the goal line). The shots were performed in random order, aiming to hit the top left
(TL), top right (TR), lower left (LL) and lower right (LR) of the goal. The efficacy of the throws was determined by video analysis, calculating the ratio of number of attempts and goals.
Results:The best efficacy was without goalkeeper (75.8%). With the goalkeeper positioned in line was 35.0% and 48.3% to advanced goalkeeper. Therefore, the lower efficacy was with the
goalkeeper positioned on the goal line. According to the proposed targets, which had the best efficacy was 66.7% (LR), followed by 58.9% (LL), 44.4% (TL) and 42.2% (TR).
Conclusions:The throw against goalkeeper positioned on the goal line is less effective than advanced, suggesting that remain under the goal increase save chances on the 7-meters,
considering the competitive level of this sample. These results may contribute to the goalkeepers define their positioning strategies.
