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.
在Wistar大鼠中，游泳3小时后，肝脏中的糖原水平在7小时内一直维持在较低水平。运动后立即给予蔗糖，肝脏糖原含量迅速增加。在运动后第3至5小时，观察到肝脏糖原出现二次减少。给予蔗糖可抑制运动期间升高的血糖浓度的降低。然而，运动7小时后，蔗糖处理的大鼠出现了轻微低血糖。运动后立即一次性给予蔗糖并不能确保肝脏糖原储备完全补充。
