Abstract: With the aging of population in China, sarcopenia has become one of the important problems in the field of public health. Sarcopenia (sarcopenia for short) is a syndrome with a high incidence in the elderly, especially in the long-bedridden elderly. The disease is characterized by decreased muscle mass, decreased muscle strength and decreased muscle function. Sarcopenia in the elderly directly leads to an increased risk of falls, decreased independence, and increased hospitalizations. The etiology of sarcopenia has not been identified, and many potential mechanisms have been studied.
