Abstract content: drink to prevent excessive dehydration (more than 2% body-weight loss from water deficit) and excessive electrolyte change; sweat rates and sweat electrolyte content vary considerably between individuals, so programmes should be customised, e.g. by weighing before and after exercise. The abstract gives no sweat sodium or potassium figures (abstract, PMID 17277604).
