Cue utilization for soccer goalkeepers during penalty kicks
This research focuses on the special case of the penalty kick in soccer. Although quite some research has already tried to search for cues that predict where a penalty kick will be shot, this research examines, besides the already known predictive cues, new cues which could help a goalkeeper predict the direction of a penalty kick. Using a self-created database of penalty kicks (including penalty kicks from both amateurs and professionals), we analyze 20 cues that are potentially predictive for the direction of a penalty kick for professionals, as well as 20 cues for amateur players. A model based on the hip position, type of kick, and velocity of the run-up allows us to correctly predict the direction of a penalty kick in 68.2% of the cases, using a sample of professionals. Furthermore with the use of an amateur sample, a model was created based on the direction of the non-kicking foot, the hip position, type of kick and the height of a shot which allows us to predict 83.0% correctly for the direction of the penalty kick. Although these are decent results, elaborate models have less practical use for a goalkeeper. For this reason, with the use hierarchical tree models, more practical guidelines were formulated in order to help goalkeepers become better a predicting the direction of penalty kicks. From these guidelines, the direction of the non-kicking foot, the position of the hip and arm stretching were identified as most promising. The type of kick, the velocity of the run-up and the stretch of the arm were newly found cues to have a relationship with the direction of a penalty kick.
