The goal of the research was to analyze the awareness of the moods in two basketball teams, taking into account the type of motor task and the result. The research was conducted on players belonging to the Spanish Amateur Basketball League and on players in the female children's selection during the 2010-2011 season. Three registers were carried out, each one consisting of four sessions, one for each type of motor task. Mood states were recorded before warming up, in the middle of the session and at the end. In order to evaluate them, a reduced version of the Profile of Mood States questionnaire was chosen. A generalized estimates equation model was used, obtaining the following results: a) the different types of motor tasks activate differing mood states; b) a defeat's role as a detonator for negative emotional states is emphasized; c) duels between players, when combined with a loss, generate negative mood states both in boys as well as in girls; d) non-opposition motor tasks (psychomotor and cooperative tasks) activate positive mood states, and can thus be used as affectivity regulators.
