Enoka's Neuromechanics of Human Movements is basically 'the book' for this type of stuff. This is where most of the information has been synthesized and you can reference any individual studies that you might want to read through right from there. You might also take a look at nwlifter's site http://www.hypertrophy-research.com/, specifically the page for contraction and fatigue http://hypertrophy-research.com/page5.html. Lots of great stuff there.
