I appreciate your response pobre, but I can't agree. Nutrients make their way into cells throughout the day without ultra-high GI carbs, so the ion channels that the cell walls use to shuttle nutrients across are not reliant upon a dextrose induced insulin spike. I have to agree with cooker that any carb will yield an insulin response. I assume the dextrose just makes it happen faster. So why is instant feeding of fatigued cells with dextrose more favorable than letting the body break down solid food? Does using dextrose maximize gains or help recovery? Or does is just boost a good pump?
Again, you are missing the key physiological point....it is all about bringing an ion channel to the membrane of
muscle cells. Glucose ingestion does this very favorably via GLUT4. Other simple sugars, such as fructose, will trigger another member of the GLUT family (there are actually 12) of transporters in the
liver and this is not what you want post-workout. The whole purpose of taking the dextrose is to initiate GLUT4 exocytosis to the cell membrance from the intracellular vesicles they are stored in. This will allow the glucose, and more importantly, your whey protein and creatine, to be delievered to the cell in a manner far more rapidly, and efficiently, than in the absense of your dextrose.
Bottom line is, take your dextrose post-workout. 2:1 ratio of carbohydrate to protein. Throw your creatine in as well.
