What is it about?
The position paper represents the current scientific recommendations for fluid management in sports: - Sporting activities should always be commenced with a balanced fluid level. - In the case of activities lasting longer than one hour it is advisable to drink beverages rich in carbohydrates (4-8 %) and sodium (400-1100 mg/l) in order to replace sweat losses. - After sport fluids and electrolytes must be replaced. For quick and complete rehydration, approximately 1.5 l of rehydration beverage per kg weight loss is recommended.
