Objetivo: Descrever e comparar o perfil da força muscular isocinética dos músculos extensores e flexores do joelho de futebolistas e voleibolistas profissionais. Metodologia: Foram avaliados 21 futebolistas e 13 voleibolistas através de um dinamómetro isocinético da marca Gymnex ISO-1 com o protocolo de 6 e 8 repetições máximas, a 60º/s e 180º/s, respetivamente. Resultados: Não foram encontradas diferenças significativas no peak torque entre os futebolistas e voleibolistas. O peak torque/body weigth dos flexores do membro dominante a 180º/s e membro não dominante a 60º/s encontra-se significativamente maior nos futebolistas em relação aos voleibolistas. O mesmo acontece com a razão convencional isquiotibiais/quadricípite do membro dominante a 180º/s e do membro não dominante a 60º/s.Conclusão: Os futebolistas apresentaram valores significativamente superiores no peak torque body weigth nos flexores do joelho do membro dominante na a 180º/s e membro não dominante a 60º/s. O mesmo acontece com a razão convencional isquiotibiais/quadricípite onde os futebolistas apresentam maiores valores no membro dominante a 60º/s e membro não dominante a 180º/s
Describe and compare the isokinetic muscular strength profile of the knee extensor and flexor muscles in athletes of football and volleyball. Methods: Were assessed 21 football and 13 volleyball players by an isokinetic dynamometer of Gymnex ISO-1 brand, with the protocol of 6 and 8 maximal repetitions, at 60º/s e 180º/s, respectively. Results: There were no significant differences in the peak torque between football and volleyball players. The peak torque/body weight of the flexors of the dominant limb at 180º/s and of the non-dominant limb at 60º/s is significantly higher in the football players in relation to the volleyball players. The same happens with the conventional ratio hamstrings/quadriceps of the dominant limb at 180º/s and of the non-dominant limb at 60º/s. Conclusion: The football players showed significantly higher values in the peak torque/body weight of the dominant limb knee flexors at 180º/s and of the non-dominant limb at 60º/s. The same happens with the conventional ratio hamstrings/quadriceps in which the football players show higher values in the dominant limb at 60º/s and non-dominant limb at 180º/s
