Creatine

An Over View

Creatine, a nitrogenous organic acid, biosynthesized (click here for pathway diagram) from the amino-acids Arginine, Glycine, and Methionine in the kindeys and pancrease, is pharmacologically referred to as an ergogenic, as, through the catalyzing enzyme creatine kinase (CK, also known as creatine phosphokinase), bonds with free inorganic phosphate hydrolyzing an ATP molecule to produce phosphocreatine (PCr) and ADP in skeletal muscle.

Creatine is considered an ergogenic, as once it is phosphorylated into Phosphocreatine, is a high-energy phosphate-store (a phosphagen) within the muscle. It releases this energy through anaerobic metabolism to re-generate ATP (free energy) in the 2 to 7 seconds following intense physical effort.

The creatine to energy reaction looks like this (2 parts); Notice that it is a cyclical reaction and acts as a spatial and temporal buffer of ATP - the energy given off from Part 1, is used to regenerate the other compound.
Part 1
creatine kinase
Free Cr + iPhospate + ATP → PCr + ADP

Part2:
PCr + ADP → Free Cr + ATP + iPhosphate

It is thought that by supplementing with free creatine, or creatine monohydrate (creatine with a sugar bound to it), one is able to increase their skeletal muscle concentrations of creatine and which, theoretically would promote faster regeneration of ATP after strenuous high intensity efforts, like training. The practical application of this reported 'ergogenic' effect, would allow an athlete to work harder, for a longer period of time - the recipe for promoting hypertrophic gains in muscle mass.

Many nutritional supplement manufacturers believe that these reported effects are absolutely true, and promote the use of creatine for the training athlete. Many athletes and coaches see the marketing hype, and accept the reported 'benefits' and think creatine is key to their training successes. But does the research support it use? Is it practical for your training? Is it appropriate for you? The materials on this page will try to provide you with what you need to know - the science and practical applications (if there are any) regarding creatine use.

To date, creatine monohydrate is the only creatine supplementation product that has been thuroughly investigated in the scientific literature and shown to be a legitimate performance enhancer. The following is a review of creatine monohydrate supplementation...Read More... It is easy to only focus on the purported benfits of creatine use, however, the training athlete must be aware of the risks associated with its use. There are several side effects that may influence your performance. Before you consider beginning a creatine supplementation regime, review the risks. The practical purpose of consuming supplemental creatine is to harness it's ergogenic properties in explosive high-intensity anaerobic exercise. This page discusses the practical application to creatine supplementation in power activities, and how it may, or may not help you.

How to Safely Supplement with Creatine - 'The Creatine Cycle' & Recommended Intake From the Lab - The Research & Science of Creatine Supplementation Performance Training Systems' Position Stand on Creatine Use What to Consult a Performance Nutritionist about your Nutrition Plan?
Several different 'loading' and 'maintenance' strategies are reported throughout the literature - which is appropriate for you? Safe creatine cycling protocols are discussed here... Do you trust the guy at the nutrition store? Do you think he's on top of his research? Educate yourself, and know what you're subjecting your body to. This page includes a collection of peer-reviewed, scientifically published research articles investigating the effects of various creatine supplementation protocols and training regimes. It is the position of Performance Training Systems, and all the members of it's team, that creatine supplementation not be recommended for training or athletic purposes, and that it is our mission to educate our athletes about the risks associated with it use.
