Abstract

Goalball is a team sport created especially for people with visual impairments that relies on audible and tactile perceptions. Its origin was aimed at the therapeutic treatment of patients and currently is a sport in the Paralympic Games. The game provides the recognition of a self-organizational cycle among teams, which are organized in three defensive principles (defensive balance, trajectory reading and block) to defend and recover the possession of the ball and three offensive principles (ball control, attack preparation and throwing to carry out the attack effectively. Based on the self-organizational cycle of goalball teams, we aim: a) measure the time used by the teams in each of the offensive and defensive principles; b) investigate the effect of time on the outcome of the offensive and defensive processes in the goalball games. For this, we will use like method the non-participant systematic observation of the context of the game, with goalball videos from Beijing 2008 Paralympic Games. The observation protocol will be composed by the record of the onset of each offensive and defensive principle throughout the matches, as well as the outcome of each attack and defense made by the teams.
