Slacklining is a sport that is gradually expanding in Brazil, reaching a diverse audience that practises it in different settings and for different purposes. The sport arrived in Brazil and was practised by climbers and young people in public squares as a form of leisure and entertainment. Currently, the sport is expanding, especially in large capital cities. The internet has proven to be a fundamental tool for the growth of the sport today, facilitating the relationship between practitioners. In this study, the objective was to investigate who the practitioners of Slackline are in Brazil and to try to identify the profile of these people, as well as their perceptions and relationship with the sport. The methodology used was a questionnaire with 23 multiple-choice questions aimed at practitioners of Slackline in Brazil; the questionnaire was disseminated through Facebook social network pages. The results show that most practitioners are young people who started practising in the last two years and learned about the sport through friends. The study highlights the potential for slacklining to become a popular sport in our country, as it is practised in public places and is low cost.
