Skeletal muscle is an important organ that utilizes iron during body movement. Movement will change the stability of iron in skeletal muscle cells. The deficiency or overload of iron in skeletal muscle cells will affect the functioning of skeletal muscle cells, thus affecting the body’s moving abilities. There-fore, the relation between movement and iron metabolism has caught the attention of more and more scholars. Transferrin receptors on skeletal muscle cell membrane, divalent metallic ion transporters, and ferroportins, have participated in iron intake and release. NO may play an important role in regulating iron metabolism of skeletal muscle in motion, but its special molecular mechanism needs for further study. In addition, hemojuvelin, which par-ticipates in iron absorption by intestines, is distributed on skeletal muscle cell membrane, its functions on regulating iron absorption by intestines in motion need to be further specified.
