Wouldn't vigorous masturbation elevate the same hormones?
Watching lots of p0rn for the T yeah. Althought it does then drop below normal level if you "consumate the relationship" so to speak. No idea how, or if, it affects IGFs or HGH.
Also supposed to be something of a feedback loop there.
Will - I think Rob Miller was pointing more towards the "big lifts" i.e. the back squat, the deadlift, the press etc...He alludes to a hormonal response that would increase strength
I'm aware of that. Which is why I sought the research to back up the premise that those "big lifts" actually do elcit such a response. And the research shows that while they do elicit a much greater response than just training the smaller muscles we would want to train (finger flexors, etc), that greater response doesn't correlate to improvement in strength or hypertrophy.
It seems that the bottom line is that the training stimulus on the specific muscle in question is the limiting factor, especially for the smaller ones where you aren't going to be building huge new amounts of mass in the best case, rather than a lack of sufficient hormonal activity/response.
EDIT: I should add, I actually do think some of those lifts are very beneficial, but not due to the hormone angle, just due to getting stronger throughout the chain...core and lower back, glutes and hip flexors. Many climbers say they train "core" and all they do is a few high rep ab exercises and do little to nothing for the lower back. Heavy, low rep deadlifts would probably benefit most climbers...provided they don't get injured...which is all too probable since many don't have a weight training background.
Here is a simplified breakdown of 10 different studies revolving around hormone response to specific weight training. Done by some folks at the University of New Mexico. Unfortunately they don't have the cited studies available to the general public as far as I can tell.
The first article uses untrained men for their study group. So I'm not sure what you're talking about regarding expecting to see increases in untrained men, since the study came to the conclusion that they didn't.
Additionally they only used a sample size of twelve (untrained) men, which is terribly small to apply these results to a larger population, let alone a trained individual. Their exercise regiment was one arm at a time per day, which is definitely not applicable to any scenario that a person would use.
