Objetivo: Comparar a força e o desempenho motor unilateral de membro superior dominante (MSD) e membro superior não dominante (MSND) entre homens e mulheres no exercício de flexão de cotovelo a 50% de 1 repetição máxima (1RM). Métodos: A amostra foi composta por 26 indivíduos de ambos os sexos, com experiência prévia em exercício resistido. Todos os participantes foram submetidos a três testes: um teste de 1RM a fim de determinar a carga dos testes, e dois testes com carga de 50% de 1RM, no qual foi registrado o maior número de repetições possíveis em MSD e MSND. Resultados: Não foram encontradas diferenças significativas na carga absoluta em MSD e MSND no mesmo gênero. Entretanto houve diferença quando se comparou as cargas máximas tanto em MSD (22,6 ± 3,9 vs. 8,72 ± 1,5) quanto MSND (22,9 ± 3,9 vs. 8,6 ± 1,6) entre homens e mulheres. Em relação ao número máximo de repetições a 50% de 1RM, observou-se que o gênero feminino realizou mais repetições tanto em MSD (27,38 ± 9,06 vs. 18,15 ± 2,30) quanto MSND (27,15 ± 6,81 vs. 17,84 ± 2,07) quando comparado ao gênero masculino. Conclusão: O gênero masculino apresenta maior capacidade de geração de força, entretanto o gênero feminino é mais resistente í fadiga com carga a 50% 1RM.
