The goalkeeper influence on ball possession effectiveness in futsal

چکیده
The aim of this study was to identify which variables were the best predictors of success in futsal ball possession when controlling for space and task related indicators, situational variables and the participation of the goalkeeper as a regular field player or not (5 vs. 4 or 4 vs. 4). The sample consisted of 326 situations of ball possession corresponding to 31 matches played by a team from the Spanish Futsal League during the 2010-2011, 2011-2012 and 2012-2013 seasons. Multidimensional qualitative data obtained from 10 ordered categorical variables were used. Data were analysed using chi-square analysis and multiple logistic regression analysis. Overall, the highest ball possession effectiveness was achieved when the goalkeeper participated as a regular field player (p<0.01), the duration of the ball possession was less than 10 s (p<0.01), the ball possession ended in the penalty area (p<0.01) and the defensive pressure was low (p<0.01). The information obtained on the relative effectiveness of offensive playing tactics can be used to improve team's goal-scoring and goal preventing abilities.

The long-term impact of practice with different task constraints on perceptual skill is relatively un-explored. This study examined the influence of extensive practice, i.e., more than a 1000 h of structured practice, with domain-specific task constraints on perceptual skill associated with the passing action. Despite performing the same passing skill, it is not known whether long-term exposure...

متن کاملBall interception by a mobile robot goalkeeper using parallel navigation
This paper deals with the feedback control of a goalkeeper. The algorithm is based on the use of geometrical rules, where the goalkeeper moves on lines which are parallel to the initial line that joins the robot and the ball. The robot moves with a constant velocity and is controlled in the orientation angle, which is a continuous function of the ball’s velocity and orientation. It turns out th...
