Background. The aim of this paper was to create cognitive models reflecting the efficiency of actions of players in individual positions existing in a modern system of play organization on the basis of a praxeological theory of team sport games. Furthermore, an attempt was made to determine the efficiency of individual and team actions of the studied teams according to the current player’s position. Material and methods. The research material consisted of 21 semi-final and final matches played during the most important football tournaments in the years 2002–2008. Actions of 26 teams playing in the 1–4–2–3–1 system of play organization were analysed. Results. It was found that the efficiency of actions of individual footballers playing according to a certain system of play organization is dependent on the position in the formation. Conclusions. Patterns of efficiency of actions of footballers playing in particular positions should be used to create models of play for lower level players.

The aim of this study was to present a model which shows the efficiency of the goalkeepers’ actions in soccer based on observations of 12 direct elimination matches during the 2010 World Cup, the 2010 Africa Cup of Nations and the 2011 Copa America. Data was recorded on observational sheet template designed by the author. Goalkeepers’ actions, efficiency and reliability, during both offensive and defensive actions, were subject to examination. The study found that during offensive actions, for goalkeepers the most effective actions are those of taking control of the field of play and keeping possession of the ball. Whereas creating a goal scoring opportunity represents only a small percentage of their actions. Defensive actions are generally performed individually by goalkeepers and they are the most reliable while catching the ball.
