Carbohydrates, Insulin and the Glycemic Index
by Casey Butt
You'll remember from the What A Weight Trainer Needs To Know About Muscle
article that glycogen is the main component in the anaerobic glycolysis
mechanism of ATP production and ATP is what fuels intense muscular
contractions. Each set you do decreases the muscles' momentary ability to
produce ATP and the substrates (including glycogen) required to produce more
ATP, and time is then needed for stores of these substrates |
