The aims of this study were to compare Brazilian Jiu-Jitsu (BJJ) experienced practitioners (EX) with beginners (IN) in relation to isometric and dynamic endurance strength, isometric maximal strength and maximal aerobic power (VO2max) and to examine correlations between tests as well. Twenty-eight BJJ practitioners were selected and divided into two groups: EX (N = 14, 33.8 ± 5.6 years; purple to Black belt, 6.5 ± 5.6 years of training in BJJ) and IN (N = 14, 30 ± 2.9 years; white belt, 0.6 ± 0.4 years of practicing BJJ). The volunteers performed tests, handgrip (dynamometer), maximum static lift (MSL) and maximum number of repetitions (MNR), the last two were conducted holding on kimono rolled around the bar, and 1600 m test for indirect determination of VO2max; which they were already familiar with, and appropriate pauses were respected. The t-tests of Student for independent samples and linear correlation of Pearson were used for statistical analysis with significance level of 0.05. The results showed that only the MSL was significantly different between groups (p <0.05) and no correlation between the different tests performed. Thus, we conclude that the specific experience in BJJ (practice time and graduations level) only influences the endurance of isometric strength and this valence, therefore, seems particularly to discriminate different levels of BJJ practitioners. Furthermore, there were no significant correlations between the tests investigated in this work.
