Abstract: The purpose of this study was to investigate the lactate response to two Brazilian Jiu-Jitsu (BJJ) matches and to determine whether there is a correlation in the lactate responses across both matches. Twenty-one BJJ black belt athletes performed two 8-min matches separated by 48 hrs. To assess lactate responses, blood samples were obtained at rest, post warm-up, and after the BJJ matches (1 min, 5 min, and 10 min post-match). There was a statistically significant increase in blood lactate concentrations after both matches compared to the pre-values (Match 1: Pre-value, 0.9 ± 0.2 mmol·L-1; Peak-value, 10.1 ± 1.7 mmol·L-1, and Match 2: Pre-value, 0.9 ± 0.1 mmol·L-1; Peak-value, 9.6 ± 0.9 mmol·L-1) (P<0.05). No significant difference in blood lactate concentration was detected for the same moments after both matches. There were weak but significant correlations in blood lactate responses at 1 min (r = 0.47), 5 min (r = 0.44), and 10 min (r = 0.47) post-match for both matches (P<0.05). High peak blood lactate concentrations of similar magnitude were detected after both BJJ matches that indicates a strong energy contribution from glycolytic metabolism. Also, the lactate responses to each match were correlated, which suggests similar individual responses across successive matches of equal duration. Still, the metabolic and physiological responses to matches may vary in actual competition due to the unpredictability of combat sports and differences in match durations.
