Desempenho de repetições e tempo sob tensão no método Cluster Sets vs. tradicional em uma sessão de treinamento de força

Introduction: Cluster sets (CLS) comes up a resistance training (RT) method that includes short intraset rest intervals. Objective: investigate acute performance in multiple sets in the CLS method vs. traditional (TRAD) Methods : 14 men trained in RT participated in this study. Subjects performed two distinct protocols: TRAD – three sets of eigth repetitions with 90% of 8 repetition maximum (RM) and two minutes rest inteval; CLS – three sets of eigth repetitions with 90% of eigth repetitions, with intraset rest of 30 seconds every two repetitions. Results : CLS method was able to maintain performance throughout sets, without significant reductions in sets 2 and 3, in both exercises. Compared to TRAD, total repetitions performed were significantly higher than for CLS than TRAD ( p ≤ 0,05). Conclusion : CLS provided greater total repetitions performed compared to TRAD. No significant differences were observed for time under tension between protocols.
