Design outcomes

Primary

Measure	Time frame
1. Body fluid balance during the 2-hour dehydration period and the 2 and 3-hour rehydration period, calculated from changes in body weight measured with an electric balance. 2. Fluid retention ratio 2-3 hours after the onset of fluid ingestion, calculated from the ingested fluid weight and fluid balance. 3. Fluid intake, which is measured by weighing with an electric balance for 2-3 hours after the onset of fluid ingestion 4. Urinary flow rate is calculated from the weight of sampled urine, in which subjects were asked to empty the urinary bladder, and the time between sampling 5. Urinary excretion rate of osmotically active substances, sodium, potassium, and chloride, are calculated from the urine flow rate and urine osmolality (osmometer), sodium, potassium, and chloride (ion-selective electrodes)	—
