ResumoBrazilian Jiu Jitsu is a high intensity combat sport practiced in conditions that promote excessive water loss, impairing the athlete's performance and health. The aim of the study was to evaluate body mass, sweating rate and perception of thirst in athletes of different ages submitted to a single experimental protocol. This experimental study had the participation of 16 participants distributed in 2 groups with an average age difference of 9,4 years; G1: (30.86 ±3.58) years, and G2: (40.33 ±2.92) years. The athletes underwent a specific training protocol lasting 60 minutes without consuming liquids. Pre and post body mass was collected, and weight loss percentage (PPP) and sweating rate (TR) parameters were calculated. G1 presented PPP of 1.05 ± 0.36 and TR of 14.7 ±4.45. G2 obtained PPP of 0.81 ±0.43 and TS of 11.8 ±6.08. Regarding the sensation of thirst, no difference was observed between the groups at the end of the protocol. We conclude the BJJ training protocol reduced body mass in both groups, and PPP and TR although no statistical differences were found, the values were absolutely lower in middle-aged athletes. Training even with water restriction did not cause thirst in all athletes. It is recommended that fighting sports athletes perform fluid replacement during sports practice.
