Previous reports have indicated that administration of a glucose-citrate (G-C) drink after a bout of exhaustive exercise results in more effective glycogen repletion in liver and skeletal muscle in rats as compared with administration of glucose alone. The present studies report the effects of the energy pattern and the type of carbohydrates, dextrin or starch from rice, in diet given following the G-C drink after exercise, on further glycogen repletion in the tissues of rats. Rats were adapted to meal-feeding 3 times a day and trained with light swimming for 7 to 10 days. On the final day of experiments, rats received the G-C drink after 2 h of exhaustive swimming and were then fed on diets with different energy patterns or carbohydrate types. Results showed that a high-carbohydrate diet is more effective than a high-fat diet for further glycogen repletion in liver and skeletal muscle. In addition, dextrin was revealed to be superior to starch as a carbohydrate source in tissue glycogen repletion. As compared with the high-fat diet, the high-carbohydrate diet, however, resulted in a lower serum free fatty acid concentration 4 h after ingestion of food possibly by decreasing adipose tissue lipolysis.
先前的报告表明，与单独给予葡萄糖相比，在一轮力竭运动后给予葡萄糖 - 柠檬酸盐（G - C）饮料能使大鼠肝脏和骨骼肌中的糖原再合成更有效。本研究报告了运动后饮用G - C饮料后所给饮食中的能量模式和碳水化合物类型（糊精或大米淀粉）对大鼠组织中糖原进一步再合成的影响。大鼠适应一天喂食3次，并进行7至10天的轻度游泳训练。在实验的最后一天，大鼠在力竭游泳2小时后饮用G - C饮料，然后喂食具有不同能量模式或碳水化合物类型的饮食。结果表明，高碳水化合物饮食在肝脏和骨骼肌的糖原进一步再合成方面比高脂肪饮食更有效。此外，在组织糖原再合成方面，糊精作为碳水化合物来源优于淀粉。然而，与高脂肪饮食相比，高碳水化合物饮食在摄入食物4小时后可能通过减少脂肪组织脂解导致血清游离脂肪酸浓度较低。
