Hydration is important

Sports drink is a beverage that designed to help athletes rehydrate when body fluids are depleted after training or competition. Electrolyte replacement promotes proper rehydration, which is important in delaying the onset of fatigue during exercise. As the primary fuel utilized by exercising muscle, carbohydrates are important in maintaining exercise and sport performance.

There are three types of sport drinks:

  1. Some contain a higher concentration of salt and sugar than the human body: Hypertonic sport drinks.
  2. Some contain a lower concentration of salt and sugar than the human body: Hypotonic sport drinks.
  3. Some contain similar concentrations of salt and sugar as in the human body: Isotonic drinks.

Isotonic drinks are often preferred by athletes because they contain a small amount of carbohydrate (less than 8%) and sodium. This carbohydrate content provides a small amount of extra energy – always helpful on a long run – but it’s the sodium that’s crucial. In isotonic drinks, you find the same concentration of sodium as you get in blood plasma. Here’s how the word came about: “iso” means “equal”, and “tonos” means “pressure” in Greek language. Put them together and you get “isotonic”.
