Introduction: Hosting mega-sport events can be an important political strategy for promoting the sport. Brazil had a decade with different mega-sport events, so we want to highlight how many Brazilian young people have been practicing sports throughout this period. Methods: This secular trend was attended by over 37.000 young people during January 2007 and December 2018. This data is part of a project aimed at mapping physical fitness, growth indicators and sports practice of young Brazilians. Data were described using descriptive statistics techniques. Results: The girls' sport practice was always smaller than boys, despite the decrease in the practice of the boys in 2012. We note a substantial upsurge in the years before the Olympic Games. Especially in Brazil, the years before Rio's Olympic Games happened the men's soccer world cup and men's confederations cup. In this year’s we note a substantial upsurge in sports practice. However, soccer, futsal (boys) and volleyball (girls) are the most practiced sports. Implications: From these results, the strategies for promoting sports can be revaluated. Understanding which sports are the most and least practiced by children is a first step towards directing policies for the promotion and democratization of sports, regardless of the sport.

大型体育赛事十年巴西儿童和青少年体育实践的长期趋势

简介：举办大型体育赛事可以成为促进这项运动的重要政治策略。巴西有十年举办过不同的大型体育赛事，因此我们想强调一下在此期间有多少巴西年轻人一直在从事体育运动。方法：在 2007 年 1 月和 2018 年 12 月期间，超过 37.000 名年轻人参与了这一长期趋势。该数据是旨在绘制巴西年轻人身体素质、成长指标和运动实践的项目的一部分。使用描述性统计技术描述数据。结果：尽管2012年男孩的运动量有所减少，但女孩的运动量始终小于男孩。我们注意到奥运会前几年出现了大幅增长。尤其是在巴西，里约奥运会前几年，男子 足球世界杯和男子联合会杯。在今年的比赛中，我们注意到体育实践出现了大幅增长。然而，足球、五人制足球（男孩）和排球（女孩）是最受欢迎的运动。启示：从这些结果中，可以重新评估促进体育运动的策略。了解儿童最常参加和最不参加的运动是指导促进运动和运动民主化政策的第一步，无论是哪种运动。
