After weight training, there is a need to refill glycogen stores, although they are not likely fully depleted.
To compensate for this glycogen reduction, athletes will often take in a large amount of carbohydrates in the period immediately following exercise. Typically, high glycemic index carbohydrates are preferred for their ability to rapidly raise blood glucose levels.
For the purpose of protein synthesis, protein or individual amino acids are ingested as well.
