OK guys, thoughts please
I have been arguing on FB with several people over hypertrophy v hyperplasia
This photo started it
my point is that he has no "ADDITIONAL" muscle TISSUE form the firts pic to the second.
He had made the muscles larger and hes gotten fatter
Everyone seems to believe that hes adding NEW MUSCLE to his frame whe in fact all hes doing is expanding the muscles he has
Hypertrophy is building muscle size
Hyperplasia does not happen in humans, there is very little scientific evidence at all.
Here is an interesting article on muscle fibres

Muscle fibers experience two specific types of hypertrophy. Myofibrillar hypertrophy refers to the increase in size or thickness of individual actin and myosin protein filaments, which can improve the force-production capacity of individual fibers. Myofibrillar hypertrophy does not lead to larger muscles; rather, it results in thicker muscle fibers capable of generating more force. Sarcoplasmic hypertrophy is an increase in the volume of the semifluid interfibrillar substance surrounding an individual muscle fiber. This fluid contains the proteins used to promote tissue repair and growth. The muscle “pump” that bodybuilders work to achieve is actually sarcoplasmic hypertrophy—the cross-section of muscle fibers will increase, but most of the enhanced muscle size is due to an increased volume of the sarcoplasm and non-contractile proteins not directly involved with force production.
A simple example of why we dont increase the NUMBER of muscle fibres is that we eventually stop growing no matter how hard we train or how many drugs we take
Also the fact that after we stop training we shrink back down to how we looked prior to training shows we dont increase fibres, yet after three months back training we blow back up to what we were due to the cfact the fibres were previously streched so they just fill up again.
Also we wouldnt have stubborn bodyparts that simply wont improve if we could inrease muscle cells/fibres
oh, and a calorie is just a calorie.
