Carbohydrates are the body’s fuel. They are macronutrients which provide energy to cells, particularly brain and muscle cells during exercise1.
The body breaks down carbohydrates during the process of metabolism to release energy, and the body is also able to store a limited amount of this energy as glycogen in the muscles and liver. The most common type of carbohydrate found in sports drinks is sugar.
When a person has insufficient fuel, it can result in fatigue, a reduced ability to train, impaired competition performance, and a decrease in immune system function1
