Abstract: This study compares technical-tactical and physiological parameters between lightweight and heavyweight male Brazilian Jiu-Jitsu (BJJ) fighters. We included 11 adult BJJ fighters (lightweight: age = 28 ± 7 years; body mass = 73 ± 2 kg; height = 1.72 ± 0.7 m; body mass index = 25 ± 2 kg/m2; heavyweight: age = 27 ± 3 years; body mass = 95 ± 6 kg; height = 1.87 ± 0.6 m; body mass index = 27 ± 2 kg/m2). Six participants were considered lightweight (71 to 77 kg) and five heavyweight divisions (88 to 101 kg). Initially, sample characteristics and a graded exercise test determined the physiological parameters. A simulated competition (10 minutes maximum) assessed technical-tactical characteristics, Heart Rate (HR), Rate of Perceived Exertion (RPE), TRaining IMPulse based on HR, session-RPE, and time at HR intensity zones (Z1, Z2, and Z3). A comparison test revealed that heavyweight athletes exhibited a higher height, body mass, total time in low-intensity efforts per block, number of standing combat blocks, and less time in high-intensity efforts per block and lower VO2MAX than lightweight (p
