    Introduction: The performance of sequential sets for the same muscle group may cause a progressive reduction on practitioner’s ability to sustain load, on the other hand, the block model of sets may reduce such effect. Objective: Compare the strength performance of two models of sets organization (grouped and block) in well trained men. Methods:  The experimental procedure was performed in three sessions. The first session was a familiarization, and then a 10RM testing of biceps curl (BC) and triceps pushdown (TP) was conducted. The second and third sessions were randomized, and in each session just one model was used. Grouped Sets Model (GS): 8 sets of 10RM for each exercise (BC and TP) were performed, and Block Sets Model (BS): each exercise (BC and TP) was alternated every 4 sets (each block) twice, until 8 sets of 10RM were performed for each exercise. A rest interval of 2 minutes between sets and exercises was adopted. A repeated-measures ANOVA (2x2) was used. A significance of 5% was adopted. Results: GS and BS showed a decrease in impulse variable. For BC exercise, there was a decrease in impulse for GS (P<0.001), and BS (P=0.005). For the TP exercise, there were a decrease in impulse for GS (P<0,001), and BS (P=0,007). Conclusion: Both methods of strength training (grouped and blocks of sets) reduce the impulse of biceps curl and triceps pushdown at similar level.

    Introdução: A realização de séries múltiplas de forma agrupada para o mesmo grupamento muscular pode causar uma progressiva redução na capacidade de sustentação da produção de força, por outro lado, alternar a execução de exercícios em blocos de séries pode minimizar tal efeito. Objetivo: Comparar o desempenho de força antes e após dois diferentes modelos de divisão de séries (agrupadas ou em bloco) em sujeitos treinados. Métodos: Os procedimentos foram realizados em três sessões. A primeira sessão serviu de familiarização e determinação 10RM no exercício rosca bíceps na polia (RB) e tríceps na polia (ET). A segunda e terceira sessões foram aleatorizadas. Na sessão de séries agrupadas (SA) foram realizadas 8 séries sequenciais de 10RM em cada exercício. Na sessão de séries em bloco (SB) os exercícios foram alternados a cada 4 séries até que 8 séries com 10RM fossem realizadas. Um intervalo de 2’ entre séries e exercícios foi adotado. Uma ANOVA (2x2) medidas repetidas com os fatores condição (SA e SB) e momento (pré- e pós-sessão) comparou o impulso em cada exercício. Uma significância de 5% foi adotada. Resultados: Ambos os modelos (SB e SA) apresentaram redução do impulso. Para a RB houve uma redução do impulso na condição de SA (P<0,001), e SB (P=0,005). Para a ET houve uma redução significante na condição de SA (P<0,001) e SB (P=0,007).  Conclusão: Ambos os modelos de treinamento de força com séries agrupadas e bloco reduziram o impulso dos exercícios rosca de bíceps e extensão de tríceps na polia na mesma magnitude, sugerindo efeito similar de fadiga. ABSTRACTComparison on the strength performance on different models of sets organization in well-trained subjectsIntroduction: The performance of sequential sets for the same muscle group may cause a progressive reduction on practitioner’s ability to sustain load, on the other hand, the block model of sets may reduce such effect.
