Abstract:

Introduction: Football is characterized by intermittent actions of high intensity for prolonged periods that can cause large losses of sweat. The loss from 1% to 2% of body weight resulting from dehydration, compromises physiological function and negatively influences the athlete's performance. Based on this, the aim of this study was to evaluate the hydration status of university athletes in a women's football match. Materials and Methods: Twelve women football players (24.3 ±5.3 years) were evaluated during a football match. The hydration status analysis was performed through water balance, urine specific gravity (GEU) and urine color. These measurements were taken before and after the match, and better analysis was performed control of water intake and environmental stress (temperature and relative humidity). For the statistical analysis, a Student t test was performed with the Graphpad Prism 8.0 software. Results and Discussion: The players showed a loss of 1.78 ±1.0% of body weight with a sweating rate of 1.06 ±0.47 L / h and ingested 967.1 ±52.3 ml of water. There was no significant reduction in body weight (p=0.307). The GEU before the match was 1029.2 ±12.48 and at the end 1028 ±2.70, with no statistically significant difference between the moments (p=0.533) with a significant dehydration classification. Conclusion: Water intake promoted the maintenance of the previous condition of minimal dehydration, so as not to aggravate the state of dehydration, and it should reinforce the importance of starting the practice in a hydrated condition.
