%X This study aimed to identify the height obtained in the power of lower limb in soccer and futsal players, comparing the counter movement jump (CMJ) among the modalities, game positions and categories. Took part of the study 61 soccer athletes from under-17, under-20 and professional categories and 28 futsal athletes from the under-20 and professional categories. It was used a piezoelectric force platform Quattro jump. It was used descriptive statistics, student ¡°t¡± test and analysis of variance set at p < .05. No significant difference was reported in the CMJ between the soccer and futsal athletes (p = .85). Among the positions adopted by soccer players it was found significant difference (p = .02) only between those in defensive positions and those in the midfield. In the futsal athletes it was not reported significant difference between positions (p = .69). Compared to other categories no significant differences were found, neither in soccer (p = .12) nor in futsal (p = .47). It can be concluded that the soccer and futsal athletes seems to present similar level of muscle power. Those in defensive positions presented higher levels of power when compared to those in the midfield, but in futsal the athletes presented similar power levels. Independent of the category, both soccer and futsal athletes presented similar level of muscle power. Este estudo objetivou identificar a pot¨ºncia de membros inferiores em jogadores de futebol e futsal, comparando o counter movement jump (CMJ) entre modalidades, posi  es adotadas e categorias. Participaram 61 atletas de futebol das categorias Sub17, Sub20 e profissional e 28 de futsal das categorias Sub20 e profissional. Utilizou-se uma plataforma de for a Quattro Jump do tipo piezoel¨¦trica. Foi utilizada estat¨ªstica descritiva, teste t de Student e an¨¢lise de variancia a p < .05. N o foi reportada diferen a significativa no CMJ entre os atletas de futebol e futsal (p = .85). Entre as posi  es adotadas pelos jogadores de futebol encontrou-se diferen a significativa (p = .02) apenas entre os centrais e os m¨¦dios. Nos atletas de futsal n o foi verificada diferen a significativa entre as posi  es (p = .69). Quando comparadas as categorias tamb¨¦m n o foram constatadas diferen as significativas, tanto no futebol (p = .12), quanto no futsal (p = .47). Pode-se concluir que os atletas de futebol e futsal parecem apresentar n¨ªveis semelhantes de pot¨ºncia muscular. Os centrais apresentaram maiores n¨ªveis de pot¨ºncia quando comparados aos m¨¦dios, por¨¦m no futsal os atletas apresentaram n¨ªveis similares de pot¨ºncia. Independente da
