[...] Source: www.marathonguide.com Carbohydrate intake within two hours of endurance exercise is essential to building adequate glycogen stores for continued training. The reason for this is that carbohydrate consumption stimulates insulin production, which aids the production of muscle glycogen. Combining protein with carbohydrate in the two-hours after exercise nearly doubles the insulin response, which results in more stored glycogen. Carbohydrate to protein ratio for this effect is four grams of carbohydrate for every one gram of protein. Solid foods can work just as well as a sports drink, a drink may be easier to digest make it easier to get the right ratio and meet the 2-hour window. [...]
