Soccer is a sport with physiological demands among energy systems. During a match the athlete performs a high intensity effort with actions of moderate intensity, which makes the modality with an intermittent character, in other words, with the participation of different energy systems. There are three distinct and integrated energy systems to perform the energy demand of skeletal muscle: the Alkaline Anaerobic System; Lactic Anaerobic System; and the Aerobic System. The average distance of the player in an official match is 10.80 Km, of which 60% of the total time in the game is represented by walking and 30% by jogging; the remainder is divided into maximum spikes. Because of this, the participation of the three energy systems occurs throughout the game. However, one system will be predominant over the other, according to each specific situation that a soccer match requires. For this reason, Carbohydrate is an organic molecule essential to both anaerobic and aerobic metabolism and its ingestion is a necessary factor so that the soccer athlete can start the game with an adequate concentration of that nutrient. But nutritional strategies should be adopted by taking into account the glycemic index and glycemic load of carbohydrate-source foods so that low-glycemic foods are ingested before the match, to provide energy during it and foods with high glycemic index after the game, to recovery faster and to improve the performance of soccer athletes
