Aggressiveness in sports, besides being something new, is object of controversy in relation to a variety of theories on this subject. As a worldwide socially spread subject, it certainly has not been investigated by social and human sciences the way it should be. The objective of this dissertation was the collection and analysis of soccer players' behavior. This study analyzed 125 senior players, belonging to the Principal League of Portugal in 2000-2001 and 88 junior players belonging to the two subdivisions (17 and 18 years old). The age of the senior players ranged from 20 to 35 years old, whereas the age of junior players ranged from 17 to 19 years olds. This study involved the application of Bredemeier Athletic Aggression Inventory (BAAGI). The findings suggest that the senior players present higher rates of reactive or hostile aggressiveness, demonstrating a statistically significant assessment between the number and the kind of cards (yellow and red) received by the athlete, as well as their self-assessments in terms of aggressiveness.
