Introduction: In futsal, there is a large production of sweat with consequent loss of fluid and electrolytes. Such loss can cause various organic disorders including dehydration, capable of compromising performance during exercise and harm health. Objective: To assess the water loss and hydration habits of college athletes of competitive futsal. Methods: Data were collected on two non-consecutive trainings (A and B), in which the variations of weight of 17 male athletes pre- and post-workout were checked. Specific formulas have been used for the evaluation of variations. The athletes drank 360 ml of water 40 minutes before training, and other liquid intake and urinary excretion were not allowed. Hydration habits were identified through a questionnaire containing objective questions related to the topic. Results: The water loss during training A was 1.02 ± 0.28 kg and during training B was 1.18 ± 0.44 kg, corresponding in percent dehydration of 1.40 ± 0.38% and 1.59 ± 0.56%, respectively. There was a significant difference between sweating rate of training A and training B (p < 0.0474). The whole group (100%) used to hydrate during trainings and competitions; 52.95% showed indifference to the type of beverage ingested; water is the most consumed hydrating solution (100%), followed by natural juice (88.23%) and coffee (76.47%). The most important symptoms of the dehydration were intense thirst (88.23%), feeling of loss of strength (82.35%) and fatigue (82.35%). Conclusion: The evidenced water loss in training was significant, as it implies the beginning of dehydration. Most athletes have inadequate hydration habits, especially when compared to the level of understanding of the subject. It is suggested the strengthening guidance and establishment of strategies aimed at ratifying the seriousness of the matter and mitigate potential risks associated with heat.
