Answer: Sure. I’m guessing you’ve already done a google search, so I’ll show you some other sources you have access to. Medline (also known as PubMed) is the best source for scholarly articles in the field of medicine. I found a number of good results in the database using keywords sports, (diet or Nutritional Requirements ) and adolescent. The easiest way to find more articles, and to get the full text of those available, is to go into the database (at www.mannlib.cornell.edu, select medline under top databases at the top in the middle_) and do the search. One nifty way to get more articles is to use the citing articles and related articles features to the right of any reference.
Some of the article titles I found were “Nutritional requirements of the child and teenage athlete” and “Special nutritional concerns for the female athlete.”
Oh, and also, try a similar search in catalog.library.cornell.edu to see about books on this topic. You can have books shipped from Mann to your Extension office for free.
This is probably enough to get you started–feel free to let me know when you need some more help.
