    The purpose of this study was to analyze the relation between substitutions and results of football matches in championships and national Cups. One hundred and twenty-nine championship matches and 129 national Cups matches were analyzed (258 in total), which occurred during the 2016-2017 season in 16 countries. Away and home games were analyzed. During the championships, 737 player substitutions were made and 721 substitutions in national cups. The match reports were analyzed to collect data, and the ANOVA was used to compare the analyzed tournaments. The results showed that the substitute players scored 10,76% of all goals, corresponding to 26,19% of the goals scored after the first substitution. In the National Cups, the substitute players were responsible for 10% of the goals scored, which corresponded to 24,84% of the goals scored after the first substitution. The teams playing in championships had more goals scored after the first substitution (p=0,013), after the third substitution (p=0,008), and after all substitutions (p=0,000), comparing to the teams playing in national cups. This research showed the importance that the players` substitutions have in modern football, becoming an indispensable strategy. Finally, the substitutions seems to be essential to coaches improve team performance.

Os relatórios dos jogos foram utilizados para coletar as informações, e a ANOVA foi utilizada para comparer os torneios. Os resultados mostraram que os jogadores que entraram na partida marcaram 10,76% dos gols, correspondendo a 26,19% dos gols marcados após a primeira substituição. Nas copas nacionais, os substitutos foram responsáveis por 10% dos gols marcados, representando 24,84% dos gols após a primeira substituição. Equipes jogando os campeonatos fizeram mais gols após a primeira substituição (p=0,013), após a terceira substituição (p=0,008), e após todas as substituições (p=0,000), comparado com as equipes jogando em copas nacionais. Essa pesquisa mostrou a importância dos jogadores substitutos tem no futebol moderno, sendo a troca de jogadores uma estratégia indispensável. Finalmente, as substituições são essenciais para que os treinadores possam melhorar o desempenho da equipe.ABSTRACTWhat can coaches do?
