Vitamin B6: Functions, Complexities, and History
In recent years vitamin B6 has become a focus of research describing the compound’s critical function in cellular metabolism and stress response. For many years the sole function of vitamin B6 was considered to be that of an enzymatic cofactor. However, recently it became clear that it is also a potent antioxidant that effectively quenches reactive oxygen species and is thus of high importance for cellular well-being. In view of the recent findings, the current review takes a look back and summarizes the discovery of vitamin B6 and the elucidation of its structure and biosynthetic pathways. It provides a detailed overview on vitamin B6 both as a cofactor and a protective compound. Besides these general characteristics of the vitamin, the review also outlines the current literature on vitamin B6 derivatives and elaborates on recent findings that provide new insights into transport and catabolism of the compound and on its impact on human health.

Vitamin E and C for Strength and Bodybuilding: Should You Take Them for Exercise Induced Oxidative Stress?
Oxidative stress is an imbalance between free radicals (pro-oxidant molecules) and the body's oxidative defense mechanisms. Primarily the free radicals in our bodies are derived from the consumption of oxygen but there are many possible radical species. The basic definition is a particle that contains one or more unpaired electrons and this can be true of many different substances. However the most important ones for us are those derived from oxygen or nitrogen. They are called reactive oxygen/nitrogen species or RONS for short.

Controlling Anxiety During Lifting
Much of the Getting in the Zone series of articles are focused on areas of sport psychology. Having psychologists help athletes perform better is a relatively new thing. While I have drawn from that, as I read some of the articles on this subject (controlling anxiety, etc) from sport psychologists, I wonder if many of them really "get it". Sure they understand the statistics and have a background in the psychology effecting performance, but have they ever been there? Do they know what it feels like? I read with interest an article in the "Mind Games" section of the NSCA's performance training journal by Suzie Tuffey Riewald entitled "Help, I'm Nervous". It's related, of course to my Getting in the Zone series of articles.

Why Programs Work
I've never seen a strength training or bodybuilding program developed for a mass audience that didn't "work". No matter how ridiculous the program is and how unfounded it's principles all such programs tend to be seen as largely successful.

Fight Or Flight: Lift or Die?
Have You ever heard someone say that in order to lift a very heavy load they imagine they are "doing battle" with the bar? Of course the real hardcore lifters don't say the word bar, they say "iron". "It's just me and the iron in a battle to the death," they say, or some such similar nonsense.1
