Document Summary
Effect of quantity of cho ingested during exercise on cho oxidation rate: Dotted lines represent the oxidation rate when it equals ingestion. In a perfect world, the more you consume the more you should oxidize. not the case with carbs- not linear but theres a plateau. O2 rate increases until you reach a limit and can"t oxidize anymore. Glucose is oxidized at a higher rate than fructose and galactose because once those are absorbed they need to be converted into glucose. The pressure the molecules form are low so can get greater concentration of glucose polymers. 1-1. 1 g/min and will enhance glucose concentration. Once fructose and lactose are absorbed, need to be converted. attribute to low rates of oxidation of this type of sugar. When you combine certain sugars may be able to increase o2 rate. Med-glu: participant had 1. 2 g/min and this made 0. 8 g/min oxidation of carb.
