Physiological and perceptual responses of a guard passing test and a simulated Brazilian jiu-jitsu combat: a pilot study. J Strength Cond Res XX(X): 000-000, 2024-Brazilian jiu-jitsu (BJJ) is a grappling combat sport characterized by high-intensity efforts during the scoring actions interspersed by low-intensity actions or pause during the referee stoppage. Therefore, understanding of the physiological response to a BJJ match and BJJ-specific test can contribute to both athletes testing and training prescription. Thus, the present study aimed to compare the physiological and perceptual responses to a guard passing test (GPT) and to a simulated BJJ combat (simulated combat [SC]). For that, 7 male BJJ athletes performed a BJJ SC and the GPT at different days at random order. GPT was composed by 6 sets of all-out guard passing movements. Heart rate, blood lactate concentration ([La]), and rate of perceived exertion (RPE) were measured immediately after SC and after each set of GPT. RPE increased after sets 4, 5, and 6 compared with set 1, with no differences to SC (p < 0.001). In additionally, no differences were observed between [La] or heart rate after SC to GPT. Results suggests that GPT is an efficient training protocol that elicits similar physiological and perceptual responses to BJJ combat. Future studies should investigate GPT reliability and validity for performance assessment.
