Heavy Weight Training, New Muscle Fibers
More articles from this author:2007-09-03 06:15:00 Muscle biopsies from the quads of strength-trained athletes after heavy resistance exercise showed an increase in mRNA and protein expression of a particular myosin heavy chain (MHCneo). Essentially, this suggests hyperplasia ? the formation of new fibers ? something that hasn't been proved conclusively in humans. Only 10 of the 26 subjects showed this effect, so it may just be luck of the genetic draw. Why grow your muscle fibers bigger when you can just make new ones?!
