Glycogen carbohydrate loading

Let us view more details of carbohydrate loading procedure. With fasting after exercise, muscle glycogen is restored, but only at a slow rate. A maximal rate of muscle glycogen restoration occurs with glucose or sucrose consumption. Fructose consumption can also restore muscle glycogen, but only at half the rate produced by gluco.se or sucrose. 

EXAMPLE 13.26 Manipulation of glycogen concentration by exercise or dietary intervention is often referred to as carbohydrate loading. The strategy favored in the late 1960s was a highly invasive program that involved two exhaustive...

The liver s role is to maintain chemical homeostasis and it can, in certain circumstances, be stressed by means of a metabolic load. One example has been to administer an oral fructose load which causes minimal spectral changes in normal subjects but, at very low dosage, results in an increase in the fructose-1-phosphate peak in patients with fructose intolerance. Other metabolic stresses have been administered to investigate galactose intolerance, glycogen storage diseases and cirrhosis. The rat liver (in situ or perfused) has been studied to elucidate details of carbohydrate and fatty acid metabolism, sometimes by a combination of and P NMR. The control of pH in the liver has also been studied.
