dc.description.abstractA simple method has been recently proposed to assess acute hydration status in humans; however, several questions remain regarding its reliability, validity, and practicality. Objective:Establish reliability of a simple method to assess euhydration, that is, to analyze whether this method can be used as a consistent indicator of a person ́s hydration status. In addition, the study sought to assess the effect exercise has on urine volume when euhydration is maintained and a standardized volume of water is ingested. Methods:Five healthy physically active men and five healthy physically activewomen, 22.5 ± 2.3 years of age (mean ± standard deviation) reported to the laboratory after fasting for 10 hours or more on three occasions, each one week apart.During the two identical resting euhydrationconditions (EuA and EuB), participants remained seated for 45 minutes. During the exercise condition(EuExer), participants exercised intermittently in an environmental chamber (average temperature andrelative humidity = 32 ± 3°C and 65 ± 7%, respectively) for a period of 45 minutes and drank water to offset loss due to sweating. The order of treatments was randomized. Upon finishing the treatment period, they ingested a volume of water equivalent to 1.43% body mass (BM) within 30 minutes. Urine was collected and measured henceforth every 30 minutes for 3 hours. Results:Urine volume eliminated during EuExer (1205 ± 399.5 ml) was not different from EuB (1072.2±413.1 ml) or EuA (1068 ± 382.87 ml) (p-value =0.44). Both restingconditions were practically identical (p-value =0.98) and presented astrongintraclass correlation(r = 0.849, p-value =0.001). Conclusions:This method, besides simple, proved to be consistent in all conditions; therefore, it can be used with the certainty that measurements are valid and reliable.es_ES
