Intro to sports nutrition

I came across a good article, Pre-season nutrition for sports, which covers the basics of sports nutrition.  It starts off talking about using the off-season for weight loss and tuning your body composition.  But while the title suggests that this is the main theme of the article, it quickly moves into in-season dietary topics.  These include pre- and post-workout nutrition; hydration; and why high-protein, low-carb diets are not a good idea for athletes.
