DaCypher,
Will try to locate the thesis. It was done at Utah State University and the author was my trainer. I'll see if he can send me the info. The study was great. We began the 8 week experiment by taking body fat measurements and doing 1 rep max on deadlift. At the close of the study, the HIT group lost bf, gained in weight lifted, and had much fewer injuries and sickness. The bottom line, the volume groug was overtrained. If you buy the theory that muscle mass increases as you perform exercise to failure (or to some point), then doing multiple reps makes no sense. Get in the gym, hit it hard, and then get out. If you are there over an hour (preferably less), then something is wrong.
