The aims of this study were to design a specific Jiu-Jitsu anaerobic performance test (JJAPT) and investigate the relationship between blood lactate ([La]), heart rate (HR) and rating of perceived exertion (RPE) during simulated Brazilian Jiu-Jitsu combat (SBJJC) and JJAPT.

The present study aimed to evaluate the effects of using hyperbaric oxygen therapy during post-training recovery in jiu-jitsu athletes.

Scientific information about the effects of caffeine intake on combat sport performance is scarce and controversial.

Brazilian Jiu-jitsu (BJJ) is a grappling combat sport that athletes, lying (guard fighter) or kneeling (pass fighter) on the mat, attempt to force their opponents to submit.

Although caffeine is one of the most commonly used substances in combat sports, information about its ergogenic effects on these disciplines is very limited.

The aim of this study was to analyze physiological responses in Brazilian jiu-jitsu athletes during simulated competition.
