Remodeling of Muscle to Match Function: Hypertrophy, Hyperplasia, Atrophy, Changes in Muscle Length
Muscle remodeling occurs, to match the requirements placed on the muscles. Hypertrophy is an increase in the total mass of the muscle, by enlarging individual muscle fibers. It occurs when the muscle is loaded during the contractile process. Atrophy, is a decrease in the total mass of the muscle, which happens when the muscle remains unused for an extended period. Hyperplasia is the increase in the number of muscle fibers, due to extreme force generation. And finally, adjustment of muscle length, occurs depending on how much the muscle is being stretched on a regular basis.

Hello, it's very nice but correct me if there's any evidence for hyperplasia in myofibers and not rather for myofibrils (that too in very few according to current literature) ? Plus as you mentioned regarding the length of muscle, i.e adding of sarcomeres in length requires to change either the origin of insertion of muscle which in any cases is clearly false according to current literature but rather the pennation angle changes to around 7 to 14 degree in angle , and hence resulting for the longitudinal fascicle growth . Thank you
