Introduction: The low hydration status can compromise cognition, technical skills and physical performance when there is a high loss of body mass. Therefore, the objective of the present study is to assess the hydration status of female futsal athletes in a competitive match. Materials and Methods: 14 players (25.9 ± 4.5 years) were evaluated during a women's futsal match. The analysis of the hydration status was performed through water balance, specific gravity of the urine (GEU) and color of the urine. These measures were performed before and after departure, and for a better analysis, control of water intake and environmental stress (temperature and relative humidity) was carried out. For the statistical analysis, a Student t test was performed with the Graphpad Prism 8.0 software. Results and Discussion: The players presented a loss of 2.2 ± 0.9% of body weight with a sweating rate of 0.68 ± 0.2 L / h and ingested 1383.0 ± 495.2 ml of water. There was a significant reduction in body weight (p=0.009). The GEU before departure was 1029.7 ± 8.3 and at the end 1024.1 ± 11.9 there was no statistically significant difference between the moments (p=0.1374) with a significant dehydration classification. Conclusion: The athletes started and finished the futsal match in a state of minimal dehydration and that, despite the environmental conditions being in a very high risk condition, the water intake promoted the stabilization of the previous condition of dehydration, so as not to aggravate that state.
