HYPERPLASIA

Heavy negatives and extreme stretching induce hyperplasia.

A perfect example of this is shown with Arnold Schwarzenegger′s pectorals. He could touch the ground when performing dumbbell flys and he arguably has the best chest in the history of the sport .On the other hand Mike Mentzer loved heavy negatives

Hyperplasia is maybe the reason why bodybuilders keep getting bigger and bigger over the years.

Do you guys incorporate heavy negatives and stretching in your training?

more drugs and a blatant disregard for asthetics are why bodybuilders are getting bigger. The training of top pros has hardly changed at all in 3 decades so that can′t be the reason.

Hyperplasia in humans has never been proven.

How the friggin hell do the pros grow??? You ever seen a Ronnie Coleman video dude throws around the weights with no regard to form!! So what makes these freaks grow??(apart from the juice).

Following is taken from abcbodybuilding.com:

Although science has evidences of hyperplasia in animals, direct proof in humans is still out of reach. The reason behind this is the sheer number of muscle fibers and our ability to count them! The tibialis anterior muscle (on the front of the leg) contains approximately 160,000 fibers! Imagine counting 160,000 fibers, for just one muscle! The biceps brachii muscle probably contains 3 or 4 times that number! (Costill, D. L., E. F. Coyle, W. F. Fink, G. R. Lesmes, and F. A. Witzmann. Adaptations in skeletal muscle following strength training. J. Appl. Physiol. 46(1): 96-99, 1979.)

We have to rely on indirect evidence for hyperplasiaÂ…however that indirect evidence provides a clear conclusion.

Some scientists have suggested that the reason many bodybuilders or other athletes have muscle fibers which are the same size (or smaller) versus untrained controls is due to a greater genetic endowment of muscle fibers. That is, they were born with more fibers. If that was true, then the intense training over years and decades performed by elite bodybuilders has produced at best average size fibers. That means, some bodybuilders were born with a bunch of below average size fibers and training enlarged them to average size. I don′t know about you, but I′d find that explanation rather tenuous. It would seem more plausible (and scientifically defensible) that the larger muscle mass seen in bodybuilders is due primarily to muscle fiber hypertrophy but also to fiber hyperplasia. So the question that needs to be asked is not whether muscle fiber hyperplasia occurs, but rather under what conditions does it occur.”
