Unlike the whole grain foods described above, pasta is an easily digestible carbohydrate. They are intended to fill the glycogen stores, which are located in the muscles, among other things. Carbohydrates are bundled in the glycogen stores and converted into energy to supply the muscles during sport. Professional athletes try to empty these stores as much as possible through intensive training in order to replenish them with light carbohydrates shortly before the competition. In this way, the glycogen stores are to be maximised in order to ensure maximum energy for the competition.
