ResumoBrazilian Jiu Jitsu is a sport that associates intense physical activity with the use of heavy clothing, usually in places where there is a high temperature, leading its practitioners to the risk of dehydration. The present study aims to evaluate the body water loss in Brazilian Jiu Jitsu practitioners during training, as well as to measure their water consumption in this context. For that, an observational, transverse and exploratory study was performed, where body mass measurements were performed before and after training; applications of questionnaires; measurement of the ambient temperature and relative humidity and statistical tests for the measured water loss. Were measured indicators of sweat loss (PS), percentage weight loss (PPP) and sweat loss per hour of activity (PSH). The results pointed to a significant variation of pre and post workout weight (p = 0.001), with mean PS of 980.69 ± 440.18 ml, PPP of 0.84 ± 0.55% and PSH of 1618.67 ± 900.78 ml / h. It is concluded that, despite heterogeneous water losses in the sample, the mean value of the percentage weight loss found is adequate when compared to the positions of specialized entities and that the average water consumption during the practice is lower than that estimated by reference institutes.
