Effect of high-fat diet intake on glycogen loading.

用几代长期喂食FAT或CHO饲料的大鼠研究了短期从高脂肪（FAT）（F-F）到高碳水化合物（CHO）（F-C）或从CHO饲料（C-C）到FAT饲料（C-F）对静息状态下肝脏和肌肉糖原含量以及长期运动后肝脏和肌肉糖原补充的影响。结果表明：（1）在运动前和运动后恢复早期，脂肪饲料（F-F和C-F）组大鼠肝脏和肌肉中的糖原含量低于CHO饲料（C-C和F-C）组。(2)与长期摄入CHO饲料（C-C）相比，长期摄入FAT饲料（F-F）引起的糖原储存能力差，通过短期摄入CHO饲料（F-C）迅速改善。

The influence of short-term changing the diet from a high-fat (FAT) (F-F) to a high-carbohydrate (CHO) diet (F-C) or from a CHO diet (C-C) to a FAT diet (C-F) upon liver and muscle glycogen contents in resting conditions and glycogen repletion in liver and muscle after a prolonged exercise bout was studied using rats fed the FAT or CHO diet for long-term over generations. The results were summarized as follows :(1) Glycogen stores in liver and muscle in pre-exercise conditions and at an early period of recovery following a bout of exercise were less in rats fed FAT diet (F-F and C-F) than in rats fed the CHO diet (C-C and F-C).(2) The poor capacity of glycogen store induced by a long-term FAT diet intake (F-F), as compared with a long-term CHO diet intake (C-C), was promptly improved by a short-term intake of the CHO diet (F-C).
