Skeletal muscle cells regenerate in mammals faster than any other type of muscle in the body, according to Miranda D. Grounds, writing for Wiley Online Library. Certain conditions are important to successful muscle cell healing.
Incurring damage to skeletal muscles usually results in damage to the cells of nerves and blood vessels, which must also regenerate and repair as the body heals, according to Wiley Online Library. When body cells die, they become unusable by the body and are necrotic. Inflammation around injuries is painful but necessary to allow the body to remove the dead tissue and replace it with new growth cells. Environmental factors such as the extent of damage in the body, how quickly the muscle injuries are addressed medically and the general health of the patient affect how quickly muscles heal.
