Soccer presents task constraints different from other team sports such as basketball or rugby. In order to analyse how that specific task constraints conditioning the interpersonal coordination patterns we proceed to analyse a sub-phase of the soccer game, the one versus one. The theoretical background was supported by the Dynamical Approach to describe how players’ behaviour alter and evolve under specific action constraints. Players’ motion was recorded by a single digital video camera. The images were digitized with the software TACTO 7.0. For the reconstruction of the bidimensional space the Direct Linear Transformations method was used. Sustain on this method we had developed our own software with the main focus to be user friendly. Based on the data we can conclude that one versus one behave as a self-organize dynamical system, and players behaviour it is not exclusively drive by internal information but by information available in the performance context. Moreover our software shows to be an accurate tool for a bidimensional reconstruction allowing a phenomenological analysis of 1vs1 situations in soccer. We suggest an extended application to other team sports.
