ResumoIntrodução: O método pareado agonista-antagonista (PAA) consiste em estimular previamente a musculatura antagonista do grupo muscular que se deseja otimizar, aumentando a ativação neural e força dos músculos agonistas. Objetivo: Comparar o método tradicional vs PAA sobre o trabalho total (TT) e volume de treinamento (VT) no exercício cadeira extensora (CE). Métodos: Doze mulheres treinadas realizaram dois protocolos experimentais randomizados: método tradicional -quatro séries da CE até a falha concêntrica; método PAA: quatro séries de mesa flexora (MF) + CE até a falha concêntrica. Foi dado um intervalo de 30 segundos entre os dois exercícios. Resultados: Pôde-se observar diferença significativa tanto no TT como VT, para o método PAA quando comparado ao tradicional. Conclusão: Sugere-se assim que o método PAA apresenta-se como melhor estratégia para otimização do desempenho de repetições máximas se comparado ao método tradicional, além de apresentar possibilidade de redução no tempo despendido para o treinamento.Descritores: Exercício; Desempenho; Força muscular; Treinamento de resistência. AbstractIntroduction: The agonist-antagonist paired set method (PAA) consists of previously stimulating the antagonist muscle of the muscle group to be optimized, increasing the neural activation and agonist muscle strength. Objective: To compare the traditional method vs PAA on total work (TT) and training volume (VT) in the leg extension exercise (LE). Methods: Twelve trained women performed two randomized experimental protocols: traditional method -four LE sets until a concentric failure; PAA Method: four sets of leg curl (LC) + CE until a concentric failure. An interval of 30 seconds was given between the two exercises. Results: A significant difference was observed in both TT and VT, for the PAA method compared to the traditional method. Conclusion: It is suggested that the PAA method presents itself as a better strategy for optimizing the maximum number of repetitions performance when compared to the traditional method, in addition to the possibility of reducing the length of training.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
