A utilização do goleiro linha e do linha goleiro na Liga Nacional de Futsal (LNF) na temporada 2018

This study aimed to analyze which teams used the tactical strategy of Goalkeeper Line-GL and Line Goalkeeper-LG in the National Futsal League in the 2018 season. Historical notes were made about these systematizations of the teams. The method of extensive direct observation was adopted by means of its own form. The sample consisted of 16 teams in 39 maches, where three matches of each team broadcast via National League TV-LNTV channel were analyzed, in the following phases: qualifying, octaves; Wednesdays; semi-final and final of the competition. Of the 16 teams, 15 used the GL and/or the LG in at least 33% of the matches; 13 teams used 67% and only six teams used GL and/or LG in 100% of matches. Of these, only one did not use GL and LG in any match, the others used GL and/or LG in at least one match. It was observed that the use of the strategies was always linked to the specific situations of the maches, such as being behing on the scoreboard or when the team was exercising a very backward marking on the defensive court. This study shows that most teams have already consolidated the use of GL and LG as a tactical game proposal, and that this proposal may be linked to specific and situations of each game. However, the most explored was LG`s tactical strategy.
