Abstract

We aimed with the present study, to observe the capacity of lactate production, and its kinetics of removal from muscle to blood, and from blood to other tissues after completion specific efforts of the Brazilian Jiu-jitsu (BJJ). We hypothesize to find high concentrations of blood lactate ([Lac]) after the fights, but until 10 minutes after observed significant decrease in [Lac]. Seven male athletes of BJJ (age = 30.4 ± 4.6 years, body mass = 85.4 ± 6.5 kg, height = 1.8 ± 0.1 m; years of practice = 5.1 ± 1.7) underwent a BJJ fight of 7 minutes length. The kinetics of lactate removal wasassessed on 6 moments: immediately after the fight (0), and 2, 5, 10, 15, and 20 minutes after the end of them. The data normality of data was determined by the Kolmogorov-Smirnov test, and analysis of difference between the means were compared using ANOVA, with significant reference value of P <0.05. We observed significant differences between collections relating to 15 and 20 to 0 (p <0.01). Our hypothesis to found a high [Lac] after exercise was confirmed. We observed [Lac] of 14.2 ± 5.9, illustrating a large contribution of the glycolytic pathway for this sport. However, the ability to remove the group showed significant decreases only 15 minutes after the end of the activity, despite some individual athletes tended to remove quickly. Observed that the [Lac] in the analyzed group were reduced significantly only at 15 compared to 0, and 20 compared to 0. Individually, it was in well-differentiated athletes for this kinetics, indicating that the ability to remove [Lac] may be subject to large intersubject individuality.
