Any active sport participation leads to a considerable loss of water. Sufficient quantities of water should therefore be consumed during and after exercising. Drinking at least eight glasses of water a day will also reduce cravings for sweet and savoury things. Drink fresh or mineral water. Energy drinks can do more harm than good. Many of them upset the body's electrolyte balance, are too sweet and contain chemicals, colourants and preservatives. Diluted fruit juices can be taken while competing. Small sips of water should be taken throughout a competition or race.
It is unnecessary to take salt tablets. They upset the body's finely tuned electrolyte balance and make you thirsty. Rather use a potassium and magnesium supplement during competitions and races.
