ABSTRACT
Multiple conditions have contributed to this end, among which people highlight the improvement of sports equipment, the refinement of preparation and observation methodologies, the progress of the coach education process and the increasing knowledge about how the human body works in sports contexts. The knowledge about the proficiency with which sports players perform their respective game tasks has proven essential for assessing the coherence of their performance with respect to the intended models of play and training. In soccer, players’ skills are largely conditioned by the environments’ impositions, that is by the successive configurations experienced by the game. A soccer team has a mutable anatomy and physiognomy that shape each other up as the game is played, being traversed by forms and flows of energy and matter that evolve in space and time. The game is profiled as an event that emerges from teams’ behaviour, which results from the way players interact under different sets of rules and various constraints.
