Effect of postexercise sucrose administration on liver glycogen repletion in rats.
In Wistar rats after swimming for 3 h, the glycogen level remained low in the liver during a period of 7 h. When sucrose was administered immediately after exercise, the liver glycogen content increased rapidly. From the 3rd to the 5th postexercise hour a secondary reduction was observed in hepatic glycogen. Sucrose administration inhibited the reduction of the blood glucose concentration which increased during exercise. However, 7 h after exercise, a slight hypoglycemia occurred in sucrose-treated rats. Administration of sucrose as a bolus immediately after exercise does not ensure a complete refilling of the hepatic glycogen store.
