Hypertrophy in a surplus I'm jiggy with. Muscle-shaping, well, I'll leave that one to the physiology geeks. I don't know enough about it to argue intelligently about it, and it really doesn't matter what I "believe" now, does it?
Hypertrophy in a cut, now that's a different matter. Outside of newbie gains - or chemical assistance - that's gonna be a tough sell, although with a muscle-pump and less fat-covering, it can certainly LOOK like hypertrophy, especially after shit-loading! Gotta love a good junk-food pump!
Mental connection I have more respect for than you might think. For one, although my undergraduate degree is in Math (Statistics, specifically), my minor concentration was Psychology, and the area I spent the most time with was brain and behaviour.
I'm dealing with a left lat that won't fire properly right now - herniated disk in my neck is pressing on a nerve - and I'm using visualization and muscle-stim among other things to retrain the connection while I floss the nerves to allow for better nutrient flow along the affected neuron. I can imagine that fatiguing a muscle under a variety of conditions would strengthen the brain-body connection, making it easier to fire and therefore, to pump and pose.
Could make an interesting article, gopro. You should write it.
I am not trying to sell you! Not at all. I was just answering your question is all. I understand you have very strong opinions on things that are not going to change, which is totally cool by me. I know what the body is capable of, and it has surprised me the things it can do when you figure out how to trick it. It's all a game of cat and mouse and you have to learn to stay 2 steps ahead, and after 20 years of mad scientist-like experimentation I feel I have gotten there. Heck, I added 120 lbs of lean mass onto my own frame without drugs, so I even shocked myself, LOL.
As for the mind thing...well, to be honest, this is where I feel you can completely separate yourself from everyone else. My degree IS in psychology, with a heavy emphasis on physiological psychology. The mind/body connection goes so deep that it truly amazes me sometimes. You mention an article, of which I have done a few small ones already...but I am actually working on a book. Hopefully with 14 hour work days 6 days a week I will find time to finish it.
An interesting note: When an athlete strongly visualizes performing a lift or a sprint or similar activity, the muscle fibers will actually fire in the same sequence as if they were actually physically performing the task! Amazing stuff!
