Why Does Creatine Work?
Improving muscle bioenergetics is one of the main ways creatine works, which I will elaborate on a bit here, and more in Part Three. One thing that occurs in your muscles from engaging in strength sports and resistance training is that you stimulate your type II muscle fibers to grow. The type II muscle fibers are the ones that can get big in size and generate fast, strong muscle contractions; they can contract very fast to generate tremendous power, when compared to slow-twitch muscle fibers which contract a slower rate of speed. For example, a 100 meter sprinter has big muscles to blast off of the starting line and run as fast as possible for a short distance. This takes big large, well conditioned fast-twitch muscles. Compare this to the marathon runner, who is faster then most people, but runs half as fast as the sprinter, but can do it for much longer. This is because marathon runners have well conditioned their type I, slow-twitch muscle fibers, with very little type II muscle fi
