The Importance of Salt in the Athlete's Diet
Athletes who sweat heavily lose large amounts of sodium during exercise, a mineral that is important for proper body function. If it isn’t replenished, it can lead to muscle cramps, low blood sodium (hyponatremia), and reduced performance.

Mineral salts and water in the diet of the athlete
Losses of key minerals such as sodium, chloride, potassium, and magnesium through sweating can negatively affect athletic performance. It is therefore important to replenish these minerals.
