The main reason for taking a serving of Micronized Creatine before training is to buffer the depletion of energy substrates in muscle that occurs during intense exercise.
Adenosine-Tri-Phosphate (ATP) is the biological currency of energy; it drives muscle contraction. Intense exercise is the most productive form of exercise. However, it promotes rapid depletion of adenosine intermediates that regenerate ATP. The inability to regenerate enough ATP quickly contributes to muscle failure during a tough set.
Creatine is a molecule that binds with phosphate easily and serves to restore ATP directly. The idea of supplementing with Micronized Creatine before training is to have a supply of ATP intermediates circulating in the blood stream during exercise. This provides muscles with an essential substrate that promotes quicker regeneration of ATP. Supplementing with creatine just before exercise promotes greater work capacity and better results from training.
