Comparação das respostas da concentração de lactato em indivíduos com diferentes desempenhos no teste de 1RM

Abstract

This study aimed to compare the responses of blood lactate concentrations in subjects with different performance in the 1RM test. Twenty-eight males, weight trained, performed a strength training protocol on bench press in smith machine, configured in 3 sets of 6 reps with three minutes rest between sets, and 60% of one repetition maximum (1RM). The sample was divided into two groups, individuals with higher value of 1RM (Group 1) and individuals with lower value of 1RM (Group 2). The blood lactate concentration was measured before, during and up to 12 minutes after protocol. The results showed no significant differences between the two groups of individuals. The data obtained in this study indicate that subjects with different performance in the 1RM test does not produce responses of different blood lactate concentration when subjected to a strength training protocol configured with the same training load.
