Well thought and written, Pellius. Not everyone around here is a knucklehead.
You are correct about the paucity of research to answer the questions about hypertrophy. However, anyone who has been to university well knows the total bias most people there have against musclemen. I encountered that plenty of times during my time at various universities. Probably the last time a good mind in a good body was appreciated was ancient Greece about 2500 years ago. Plato argued that the mind was superior to the body and the religions adopted that value. What a pity. The vast majority of people value physical pleasures and not intellectual pursuits. If someone wins a big lottery do they quit their job and go to university? I doubt it. Most quit their jobs, take a holiday, buy a better house, car, jewelry, TV, computer and so on. That is what people value.
What I can't understand is why large muscles have a bad name. Fat is despised almost universally by both sexes. It is seen as a calamity. If fat is bad then muscle should be good, right? That isn't the way our culture works. Large muscles are not valued and just about everyone believes things about musclemen to discredit having large muscles. We are stupid, musclebound, gay, obsessed and selfish individuals.
All of this helps explain why universities do not do research on or for bodybuilders. To the academics we are mirror athletes and should not be either encouraged or valued.
I am still waiting for someone to obtain a PhD in human maximum hypertrophy. Why not? People study eating disorders, and all manner of different people but almost noone is studying bodybuilders. If we admit that drugs are a big part of professional bodybuilding then that is pretty much the nail in the coffin for all of us because no one will touch us with a 10 foot pole.
