ABSTRACT

BACKGROUND:

Mitochondrial quality control is a complex process,which involves three aspectsmitochondrial biogenesis,mitochondrial dynamics change and mitochondrial autophagy,among which mitochondrial dynamics change is the intermediate link between mitochondrial biogenesis and mitochondrial autophagy.Mitochondria can improve their own quality control through dynamics change and then maintain their stable state.

OBJECTIVE:

To explore the molecular mechanism underlying the influence of exercise on mitochondrial dynamics,so as to provide theoretical basis for improving mitochondrial network homeostasis and promoting functional health.

METHODS:

Using the method of literature review,CNKI,Bailianyun Library,PubMed,Web of Science,EBCSO were searched for relevant literature with the keywords of"Exercise,Mitochondrial Steady State,Mitochondrial Quality Control,Mitochondrial Dynamics,Mitochondrial Fusion and Mitochondrial Division"in Chinese and English.The finally obtained literature was screened,read,and summarized. RESULTS AND

CONCLUSION:

Dynamin-related proteins 1/2 are responsible for mitochondrial fission,while mitofusins 1/2 and optic atrophy type 1 mediate the fusion of outer membrane and inner mitochondrial membranes respectively.Exercise training can improve the function of mitochondria by up-regulating the protein expression of mitofusins 1/2 and optic atrophy type 1 and down-regulating the protein expression level of dynamin-related protein 1,promoting mitochondrial fusion and inhibiting mitochondrial fission.The findings that a single acute exercise affects changes in mitochondrial dynamics are controversial.Furthermore,there is tissue variability in exercise-mediated changes in mitochondrial dynamics.
