What is Hyperplasia?
Very little is known about hyperplasia. Hyperplasia means the increase in the number of a cell type; hence hyperplasia is the splitting of muscle fibers. Testing done with animals has shown muscle fiber splitting; cats where subjected to heavy resistance training for a prolonged period of time. It has also been noted that many Russian scientist that increases in muscle mass is not only through hypertrophy of muscle fibers (i.e. muscle cells enlarge) but also through an increase in fiber number by means of splitting into smaller sections. It has also been documented that satellite cells, which can activate new cell formation, has been shown to be associated with muscle hyperplasia, through stretching and dynamic exercises. Many people believe that hyperplasia does exist in humans possibly through heavy intensive training sessions, but lack of human testing cannot conclude this.
