    Key Points

    • Repeated sprint activity, characteristic of football, results in a net reduction in muscle glycogen concentrations, which has been associated with impaired performance toward the latter stages of a match.​
    • The daily intake of carbohydrate should be proportionate to estimated fuel cost of the training session or match.​
    • The ingestion of 2.5 g of carbohydrate/kg BM in the “pre-match meal” three hours prior to exercise will “top up” stores of glycogen in the muscle and liver.​
    • The ingestion of 60 g of carbohydrate/h, prior to and during exercise (including halftime) will preserve endogenous glycogen and increase blood glucose concentrations. As a result, players are able to maintain high intensity running throughout the match, identified as key performance attributes of top level football players and teams.​
    • Muscle damage as a consequence of frequent changes in direction, decelerations from sprints and contact between players during match play can impair glycogen synthesis after exercise.​
    • Evidence is accumulating that carbohydrate ingestion also has a beneficial impact on skill performance, however future studies are required to determine the exact mechanisms involved. ​

    חברת משקאות אנרגיה (GATORADE) מלאי סוכרים ממנת מחקר, בזמן המונדיאל, שמצא כי צריכת פחמימות ומילוי מאגרי הגליקוגן חשובים לשחקני כדורגל? No shit!
