Over the years of scouring Pubmed and other sources for research sources that provide insight to exercise physiology, I've compiled a list of bookmarked links to relevant studies. Here is a good opportunity to organize and share them in a topical format.   The Medicine of Cycling also has a very comprehensive database of research links.  I focus more on studies that are related specifically to training and exercise physiology, and this is by no means comprehensive ...yet, but is an organic and expanding library of research.  Enjoy
