Abstract: BACKGROUND: Type 2 diabetes mellitus is a disease caused by energy metabolism disorder. Muscles and bones participate in the body’s energy metabolism regulation through their endocrine function under the condition of exercise stimulation. Currently there are few studies on the mechanism of “Muscle-Bone” Crosstalk mediated exercise regulating bone metabolism in type 2 diabetes mellitus. 
OBJECTIVE: By analyzing how exercise regulates the expression level of “Muscle-Bone” Crosstalk secretion-related factors and acting on the pathological reasons of bone tissue, to explore the mechanism of bone metabolism mediated by “Muscle-Bone” Crosstalk exercise in type 2 diabetes mellitus.
METHODS: CNKI, WanFang, and PubMed were searched for relevant literatures published in recent 10 years. The keywords were “exercise, type 2 diabetes mellitus, bone metabolism, “Muscle-Bone” Crosstalk, muscle factor” in Chinese and English, respectively. After screening, 50 eligible articles were analyzed and discussed. 
RESULTS AND CONCLUSION: Some of bioactive factors in muscles and bones act on the bones in an endocrine manner, such as myostatin, bone morphogenetic protein, musclin, etc., and the others act on the bones in a paracrine manner, such as insulin-like growth factor 1, interleukin 6, irisin, etc. These factors participate in the regulation of bone metabolism, balance the bone formation of osteoblasts and bone resorption of osteoclasts in bone tissue, and become the messenger factors of exercise-mediated musculoskeletal system. Exercise is an important means to regulate energy metabolism. Exercise-mediated internal stimulus changes can trigger the signal response of muscle cells and bone cells, activate Wnt, bone morphogenetic protein/Smads, transforming growth factor-β and other signal pathways, thereby regulating the endocrine function of the musculoskeletal system, promoting metabolic adaptation and influencing bone metabolism in type 2 diabetes mellitus. 


Key words: exercise, type 2 diabetes mellitus, bone metabolism, “Muscle-Bone” Crosstalk, muscle factor
