Final answer:
Athletes should consume high glycemic index foods after training to enhance glycogen storage.
Step-by-step explanation:
Athletes should consume high glycemic index foods after training to enhance glycogen storage. High glycemic index foods are quickly digested and absorbed, resulting in a rapid increase in blood sugar levels. This stimulates the release of insulin, which helps facilitate the uptake of glucose into the muscles for glycogen storage. Examples of high glycemic index foods include white rice, white bread, and potatoes.
