Carbohydrates and Sports Drinks

Sports Drinks containing Carbohydrates and Electrolytes can help maintain your endurance during extended training sessions and events. Carbohydrates are your brain and body's preferred source of energy. The correct use of carbs, before, during and after physical exertion can help extend your endurance, improve your performance, and speed recovery.

Simple carbohydrates or short chain carbs, sucrose (50:50 glucose:fructose), and glucose (aka dextrose), provide a quick release of energy. Complex carbohydrates, or long chain carbs - maltodextrin - provide a more stable and sustained energy source.
Fructose helps restore liver glycogen more readily than other sugars, making it beneficial for use during extended endurance exercise however it doesn't restore muscle glycogen.
