Efeito do intervalo entre as séries sobre o volume de repetições no método piramidal crescente

Abstract

Effect of rest interval between sets on the volume of repetitions in the crescent pyramidal method The rest interval between multiple sets is a key-factor that determines the ability of maintaining the number of repetitions performed in subsequent sets. In this sense, the objective of the present study was to evaluate the effect of different rest intervals in a crescent pyramidal method on the volume of performed repetitions. Six individuals performed one maximal repetition test (1RM) in the bench press. Separated by 48h the volunteers randomly performed two crescent truncated pyramid sessions, composed of 5 sets at 70%, 75%, 75%, 80% and 85% of 1RM, with one or two minutes rest interval. The number of repetitions in each set and the total repetitions performed in the five sets, for the intervals of 1 and 2 minutes were, respectively: 1st set 13.83 ± 2.14 versus 14.67 ± 2.07 (p=0.07), 2nd set 5.50 ± 1.52 versus 7.83 ± 1.47 (p≤0.05), 3th set 3.67 ± 0.82 versus 6.00 ± 1.41 (p≤0.05), 4th set 1.83 ± 0.41 versus 3.67 ± 1.51 (p≤0.05), 5th set 1.00 ± 0.63 versus 1.83 ± 1.47 (p=0.09) and the total volume 26.67 versus 33.17 (p≤0.05). It was concluded that the alteration of intervals of 1 and 2 minutes between sets modifies the number of repetitions performed in the 2nd, 3th, and 4th sets and the total repetitions during the execution of a crescent truncated pyramid
