The Physiology Of Muscle Growth. After you workout, your body repairs or replaces damaged muscle fibers through a cellular process where it fuses muscle fibers together to form new muscle protein strands or myofibrils. These repaired myofibrils increase in thickness and number to create muscle hypertrophy (growth).Sep 17, 2013
Even though both can hurt a lot, strains are not as serious as sprains. Because a strain is pain in the muscle, it may start to hurt immediately or several hours later. The area will be tender, feel sore, there may be some swelling, and it might also appear bruised.
All muscles are made of a kind of elastic tissue. Each muscle consists of thousands, or tens of thousands, of small musculus fibers. Each muscle fiber is about 40 millimeters long. It consists of tiny strands of fibrils.Apr 11, 2017
Protein is made up of amino acids. Amino acids are the building blocks of your muscles and body. Without them, it would be impossible to build, repair or even maintain muscle tissue. Protein is made up of carbon, hydrogen, oxygen and nitrogen.Dec 12, 2011
