Dehydration in endurance sports
In a sedentary person, the daily exchange of water is about 2.5 litres (intake and output), but the liquids that actually circulate in the entire digestive system amount to about 9 litres. In an athlete, the quantities vary considerably due to an increase in outflow, mainly in the form of sweat. These losses must be adequately compensated for by an increase in intake.
