The occurrence of disability in the elderly is closely related to sarcopenia. Previous views have suggested that decreased muscle mass is the key cause of disability, but recent studies have shown that the relationship between decreased muscle mass and disability is not significant. The decline in muscle strength and muscle mass is the decisive factor leading to dysfunction in elderly people, and muscle fat infiltration may play a core role. Proper nutrition and active exercise can significantly improve sarcopenia and effectively reverse the occurrence of disability. This article elaborates on the mechanism of disability caused by sarcopenia and the interventions for disability.
