Efeito de diferentes intensidades de aquecimento sobre o desempenho no exercício supino reto

Abstract

The aim of the study was to verify the effect of different warm-up intensities on the number of maximal repetitions (nMRs), Root Mean Square normalized (RMSn), subjective effort perception (SEP) and the fatigue index (FI) in multiple series the bench press. Ten men (21.00 ± 1.73 years, 23.90 ± 3.50 kg.m2) recreational practitioners resistance trainning, after performing a maximum repetition test (1-RM) performed three procedures (without warm-up, warm-up low intensity and warm-up high intensity), previous to the nMRs test, with 70% external load of 1-RM in three series, in different sessions. Assesments RMSn for the pectoralis major sternal costal (STC) and clavicular (CLA), SEP and nMRs were quantified for each series and the force FI between the first and third series. Two-way ANOVA was used to analyze possible differences in values of nMRs and RMSn, and ANOVA One-Way for FI, both were followed by Bonferroni post hoc test. Differences in SEP were analyzed by the Friedman test, followed by Dunn's post hoc. The level of significance was P <0.05. No significant differences were found for the total nMRs between the procedures, as well as the nMRs for each series of protocols. The RMSn also showed no difference in both the ESC and the CLA between the procedures, as well as the SEP and the FI. These results suggest that the proposed warm-up protocols are not capable of modifying nMRs, neuromuscular responses, SEP, and FI on bench press exercise in recreational men practitioners’ resistance trainning.
