  Introduction: The state of hydration is determinant for the practice of physical activities. Thus, assessing the knowledge and level of hydration is critical to avoiding health problems related to dehydration. Objective: To evaluate the level of knowledge and hydration of adolescents who are part of a soccer project. Materials and Methods: This is an observational and longitudinal study, with adolescents of the basic categories of UFJF football, male, aged between 13 and 17 years. Nutritional status was assessed according to BMI. The knowledge about hydration was evaluated through questionnaire and the level of hydration through weight and urine test (staining, pH and gravity), both before and after training. Results: Twenty-seven players were evaluated. According to urine color, 48.1% presented moderate dehydration. Regarding urine pH, 63% are acidic. About 80% of the density is hydrated. In the evaluation of the questionnaire it was identified that 81.5% of the players have the habit of moisturizing themselves during games with only cold water. They reported having some symptoms of dehydration as an intense thirst, in addition to having received basic guidance on hydration. Discussion: To diagnose the practice of hydration of the players allows an effective action for the correction of their habits, with strategies for the consumption of liquids before, during and after the games. Conclusion: It was verified that the players have a previous knowledge about hydration. However, they did not have a technical instruction on the subject, interfering in the level of hydration.

  Introdução: O estado de hidratação é determinante para a prática de atividades físicas. Assim, avaliar o conhecimento e o nível de hidratação é fundamental para evitar problemas de saúde relacionados à desidratação. Objetivo: Avaliar o nível de conhecimento e de hidratação de adolescentes integrantes do um projeto de futebol. Materiais e Métodos: Trata-se de um estudo observacional e longitudinal, com adolescentes das categorias de base do futebol UFJF, sexo masculino, com idade entre 13 e 17 anos. O estado nutricional foi avaliado segundo o IMC. Avaliou-se o conhecimento sobre hidratação através de questionário e o nível de hidratação através do peso e exame de urina (colorações, pH e gravidades), ambos antes e após o treino. Resultados: Foram avaliados 27 jogadores. Segundo a cor da urina, 48,1% apresentaram desidratação moderada. Em relação ao pH da urina, 63% encontram-se ácidas. Sobre a densidade, cerca de 80% encontram-se hidratados. Na avaliação do questionário foi identificado que 81,5% dos jogadores têm o costume de hidratar-se durante os jogos, somente com água gelada. Relataram ter alguns sintomas de desidratação como sede intensa, além de já terem recebido orientação básica sobre hidratação. Discussão: Diagnosticar a prática de hidratação dos jogadores permite uma ação efetiva para a correção de seus hábitos, com estratégias para o consumo de líquidos antes, durante e depois dos jogos. Conclusão: Constatou-se que os jogadores têm um conhecimento prévio sobre hidratação. Porém, não tiveram uma instrução técnica sobre o assunto, interferindo no nível de hidratação. ABSTRACT Assessment of the level of knowledge and hydration in adolescents practicing soccerIntroduction: The state of hydration is determinant for the practice of physical activities.
