An important factor to optimize physical performance is to maximize cellular levels of stored nutrients as fuel for ATP. Adenosine triphospate (ATP) is our chemical energy. 3 systems or pathways play a key role in using our chemical energy. The creatine phosphate system, anaerobic glycolysis, and the aerobic system which includes tca cycle, beta oxidation of fatty acids, and aerobic glycolysis.*
Our macronutrients turn into ATP using micronutrients as coenzymes and cofactors.* Most people are aware of needing macronutrients for this process, but often can have sub optimal levels of micronutrients in the diet.
A few of these micronutrients include the following:
- B vitamins
- vitamin c
Creatine is a key component of an energy compound called phosphocreatine. It’s made through a series of reactions that require arginine, glycine, and methionine. Once made, creatine is released into blood to the tissues with the majority going towards muscle tissue. Its found as either free form or phosphorylated form in tissues. The phosphorylated form is essentially stored as high energy phosphate phosphocreatine replenishes ATP in a muscle that is rapidly contracting.
