Objetivo. Medir a rápida perda de peso e indicadores urinários do estado de hidratação, bem como avaliar os efeitos e sintomas de desidratação em atletas de Brazilian jiu-jitsu (BJJ) em diferentes momentos. Métodos. 17 atletas de Jiu-Jitsu do sexo masculino (idade: 24,4 ± 3,5 anos; massa corporal (MC): 76,8 ± 14,6 kg; gordura corporal: 16,6 ± 6,4%), foram avaliados entre 8 e 9 horas da manhã em três momentos diferentes: Linha de base (10 dias antes da competição), aferição de massa corporal e estatura, coleta de urina e registro alimentar das últimas 24 horas; pré-competição, mensuração de MC, amostras de urina e questionário para avaliação da perda rápida de peso (RWL), e pós-competição (24h após), dia seguinte à competição, com mensuração de MC, e amostras de urina para análise de gravidade específica. Resultados. Houve tendência de diminuição da MC para competir (basal: 76,8 ± 14,6 kg, pré-competição: 75,4 ± 13,4 kg, pós-competição: 77,3 ± 13,7 kg; p < 0,07), com 88,2% dos atletas usando métodos que aumentam a desidratação. A maioria dos atletas estava desidratada nos três momentos do estudo (94,1%; USG = 1,021 ± 0,005 Usg no início, 88,2%; 1,020 ± 0,007 Usg no pré-competição, 88,2%; 1,022 ± 0,008 Usg no pós- dia da competição), acompanhada de sintomas associados a RWL (82,4% aumento da frequência cardíaca, 52,9% dor de cabeça, 47,1% ondas de calor, 41,2% náusea, 41,2% desorientação e 29,4% tontura). conclusões. Perda de peso pré-competitiva rápida e sintomas associados à desidratação foram observados nos atletas de Jiu-Jitsu. Recomenda-se que medidas educativas sejam promovidas para inibir o RWL entre os atletas de Jiu-Jitsu, exigindo o engajamento dos profissionais de saúde e dos órgãos que regem o esporte (federações e confederações).
