A Revolução Industrial promoveu profunda transformação social e política na sociedade. As cidades começaram a se constituir ao redor das fábricas, formando grandes centros urbanos, enquanto, os trabalhadores do meio rural estabeleceram-se nos subúrbios das cidades (GOMES, 2008). Em decorrência disto, esses centros urbanos possuíam diversos imigrantes sem identificação com esse espaço e, tão pouco, com pessoas locais. Na tentativa de superação desses entraves, o futebol desponta como uma atividade na qual as pessoas podiam se reunir, gerando alguma identidade de grupo. Com isso, surgem os clubes de bairros, que fazem crescer o interesse social pelas cidades urbanas. Cresce também o sentimento de pertencimento a determinado grupo ou agremiação (TOLEDO, 1996). Motriz, Rio Claro, v.18 n.1, p.186-199, jan./mar. 2012 Leisure, aggressiveness and violence: considerations over the organized fans´ behaviorAbstract: Soccer has a great social representation in many cultures. But the passion developed in the fans can born aggressive and violent behaviors in a moment that should be for fun, characterizing the deviant leisure, theme that needs more investigation. This qualitative research has a main goal to investigate, in the academics studies, the aggressive behavior of the organized fans and their consequences in the leisure time. By a bibliographical research, information were found in reference material, composed by books and thesis, besides the use of databases, with the key-words: leisure, cheerleaders, aggressiveness and violence. The results show that, independently of the genesis of an aggressive behavior, other factors could interfere. When inside a group, or depending on the social-historical context, the profile of the fans, the violence of each society, the media, the poor organization of sport and impunity, these factors can affect individual behavior, contributing to aggressive and violent manifestations in soccer context, inside the field and inside the organizations of the fans. This kind of manifestation leads to a smaller audience at the stadiums, and even creating limitations in activities of leisure context. These violent conducts can bring serious physics and/or psychological consequences. After all, is pointed the necessity of specific public policies involving leisure and the international events.
