Athletes are advised to consume sufficient amounts of sugar (carbohydrate) and fluid post exercise in order to speed up recovery. Co-ingestion of protein may also be efficacious. In this study, the effect of different drink combinations on recovery from exhausting exercise and subsequent exercise performance were investigated by directly measuring change in muscle and liver glycogen concentration using 13C NMR spectroscopy at 3T
