Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The main study parameter will be fluid balance. This will be determined by measuring urine production up to five hours after post-exercise rehydration (t=0,1,2,3,5 hours). | — |
Secondary
| Measure | Time frame |
|---|---|
| Urine samples will be analysed for osmolality and sodium and potassium content. Body composition (total body water) will be assessed by Bio-Impedance Analysis (BIA/BIS), immediately after exercise and at 2 and 5 hours after the start of rehydration. For safety purposes, breath alcohol concentration will be assessed up to five hours after post-exercise rehydration (t=0,1,2,3,5 hours). In addition, this assessment will give an indication of the velocity of alcohol degradation by the dehydrated body. | — |
