A sports drink is a drink designed to help athletes rehydrate, as well as replenish electrolytes, carbohydrates, and other nutrients, which can be depleted after an endurance activity such as running. 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.
Types of sports drinks
According to Wikipedia, there are three types of sports drinks
- Isotonic sports drinks contain proportions of water and other nutrients similar to the human body, and typically are six to eight percent sugar.
- Hypertonic sports drinks contain a lesser proportion of water, and a greater proportion of sugar, than the human body.
- Hypotonic sports drinks contain a greater proportion of water, and a lesser proportion of sugar, than the human body.
Most sports drinks are moderately hypertonic, having between 13 and 19 grams sugar per an eight ounce serving.
