Primary Outcome Measures

Name	Time	Method
<p>The main study parameter will be fluid balance. This will be determined by<br /><br>measuring urine production up to five hours after post-exercise rehydration<br /><br>(t=0,1,2,3,5 hours). </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Urine samples will be analysed for osmolality and sodium and potassium content.<br /><br>Body composition (total body water) will be assessed by Bio-Impedance Analysis<br /><br>(BIA/BIS), immediately after exercise and at 2 and 5 hours after the start of<br /><br>rehydration.<br /><br>For safety purposes, breath alcohol concentration will be assessed up to five<br /><br>hours after post-exercise rehydration (t=0,1,2,3,5 hours). In addition, this<br /><br>assessment will give an indication of the velocity of alcohol degradation by<br /><br>the dehydrated body. </p><br>
