Muscle growth can actually be attributed to the trauma caused by working out. When long bouts of weight training exercises are performed, the muscles are put under a certain amount of stress which causes “satellite cells” to activate. These satellite cells are located on the outside of the muscle fibers between the sarcolemma (plasma membrane) and the basal lamina (basement membrane). The body’s effort to repair and/or replace the muscle fiber that has been traumatized leads to the satellite cells fusing together, which leads to another process called hypertrophy. During this process, the muscle cells continue to multiply and form new muscle strands called myofibrils. Myofibrils further work to repair damage to the muscles that have been put under stress and begin to increase in number, and thicken. This thickening process starts to increase the overall muscle tissue, leading to a larger appearance. Muscles continue to grow whenever the rate of muscle protein fusion is greater than the
