The efficiency of action of futsal goalkeepers in game situations witvarying results of competition

Abstract

Purpose: The aim of the study was to expand knowledge of the efficiency of actions from top-level futsal teams. Goalkeepers’ activity, effectiveness and reliability were estimated with a view to implementing the objectives of the game in offence and defence and depending on the changing match status. Material: Data about the game were registered on a self-developed observation sheet. 23 goalkeepers participating in 31 matches of the World and the European Championships and the UEFA Futsal Cup played in the years 2012–2015 were observed. In order to estimate statistically significant differences in goalkeepers’ activity in situations of neutral, favorable and unfavorable competition scores, the results were averaged by dividing each of the applied actions in a given match by the number of minutes played during a given competition result. The outcome was the average performance of a goalkeeper in one minute of the match during a given score. The results of the activity scale, depending on the result of the match, were compared with the Kruskal-Wallis test and the post hoc Dunn Bonferroni test and the Jonckheere-Terpstra trend test. Statistical analysis was conducted with a use of the statistical package R and STATISTICA 10. Results: It was found that actions to gain the playfield with the ball and to prevent a loss of a goal dominated in futsal goalkeepers’ both when drawing as well as winning and losing game and that game status does not determine the style of play of the goalkeeper. Only in nine of the 60 types of actions examined significant differences in activity were fund Conclusions: The unequivocal claim that the current score during the competition determines the style of the futsal goalkeeper’s game (the frequency of taking actions in the game characteristic of his position), is unauthorized at this stage of research. The obtained significant differences in his activity in nine types of actions constitute only a small percentage (15%) of all his skills in the game.
