Most athletes, no matter what their special event, will do almost anything to achieve an edge over their competitors. There is no evidence that water taken during exercise causes an upset stomach or any other problem. In fact, consumption of water is very important because it helps replace body fluids lost as sweat. MYTH - Muscle cramps are caused by inadequate salt intake.
Cramps are due to severe loss of water through sweating.
Drinking adequate amounts of water before, during and after exercise can prevent this water loss. Salt tablets can aggravate this condition by drawing more water out of the muscles and into the stomach. Normal salt intake during eating should replace the small amount of salt lost by sweating. MYTH - A candy bar, honey or soft drink before exercising will provide a source of quick energy. Although sugar from these items will enter the body quickly, it can cause fatigue, hunger and dizziness.
