Specifically, we aimed to a) analyze the variation in the number of an organization participating, b) identify the variation in the type of funding, c) verify the existence of a relationship between the performance and the longevity of the organization, d) verify the existence of a relationship between the performance and the type of funding. Methods: The research was designed as an exploratory case study. A total of 86 organizations took part in the league during the period, with 767 different teams playing competitions between U-11 and senior.
