O objetivo deste estudo foi analisar a validação da equação baseada em repetições até a falha para ajuste da carga de treinamento em mulheres de meia-idade submetidas ao treinamento resistido (TR). Dez mulheres (35,5 ± anos, 67,8 ± 11,6 kg, 165,9 ± 4,5 cm, 24,5 ± 3,8 m/kg²) com experiência prévia em TR de pelo menos um ano foram selecionadas para participar desta pesquisa. As participantes realizaram duas sessões de exercício resistido, separadas por intervalos de pelo menos 48 h. Na primeira sessão, as participantes realizaram o teste de repetições máximas para determinar a carga para a sessão seguinte. A equação baseada em repetições até a falha teve como objetivo ajustar a carga para carga de 8-12 RM. A segunda sessão foi conduzida com a carga ajustada de acordo com a equação, na qual as participantes realizaram três séries até a falha. Os oito exercícios testados apresentaram médias dentro da zona de repetições de 8-12 RM. Leg press 450 = 11,3 (8,8 - 13,6), remada sentada = 11,3 (8,9 - 13,7), extensão de joelhos = 9,3 (8,5 - 10,0), supino reto = 9,2 (8,2 - 10,1), flexão de pernas = 7,5 (6,5 - 8,4), puxada alta = 8,6 (7,4 - 9,8), elevação de panturrilhas em pé = 13,6 (11,3 - 15,9) e tríceps pushdown = 11,6 (9,8 - 13,3). Os resultados sugerem que a equação baseada em repetições até a falha é uma estratégia válida para ajustar a intensidade da carga de treinamento em exercícios resistidos em mulheres com experiência prévia em treinamento resistido.
