Creatine and Phosphate Suplimnation

Anssi Manninen’s article is divided into three sections. The first deals with creatine supplements. “Creatine is a naturally occurring amino acid that is obtained from the diet and/or synthesized endogenously (within the body) from the amino acids glycine, arginine and methionine.” (Supplement Performance: Creatine Plus Phosphate, 2003, p. 138). Creatine is now the supplement of choice among athletes and is the most recognizable of all to the general public (which is in relation to the amount of media coverage that it gets). Creatine really moved into the public’s eye when Mark McGuire admitted to using it during his MLB home run record chase during 1998. Creatine has been proven, in mo

Creatine is the widely recognized leader in the nutritional supplement category. It is believed that it “…has a performance enhancing capability as important for brief intense exercise efforts as dietary carbohydrate is for activities where glycogen supplies limit performance.” (Lemon, 2002, par. 1). “Several studies have shown that creatine loading improves muscle strength and performance, either during intense, maximal exercise or during repetitive exercise when compared with the pre-loaded state.” (Culpepper, 1998, par. 6). Creatine assists in the production of ATP and helps in the process of muscle growth and strength. Manninen stresses these benefits of creatine in her article and reinforces them with facts from the 1970s when Soviet scientists conducted research into creatine supplementation. Creatine, like most other supplements does have some noted negative effects or lack of effects. When commenting on studies on creatine, Gina (2003) noted:

A possible side effect is “…from the known effect of high-protein intake on kidney function and its relation to progressive dysfunction in previously diseased kidneys.” (Culpepper). Other concerns are raised by Dempsey, Mazzone and Meuer (2002):

Most studies that have been completed on creatine monohydrate powder are done on small numbers of young, healthy males, yet effects of creatine supplementation have been shown to differ in older populations [Balsom 1994] and may be even more disparate in women, [Forsberg et al 1991] and certain ethnicitial Athletic Performance.

Lastly, the third part of the article talks about combining creatine and phosphate supplementation. A test was run by Dr. Eckerson and colleagues to examine what affects that this combination of supplementation has on the performance of a test study group. Beyond this test virtually no research has been committed to this area in the supplementation field.

In the third part of the article, it debates the value of combining creatine and phosphate supplementation for increased benefits. It cities studies completed by Dr. Eckerson and colleagues that find “The placebo and creatine groups increased anaerobic working capacity by -3.0 percent and 16.0 percent, respectively. The creatine plus phosphate group increased anaer
