Abstract:

BACKGROUND: The phenomenon of atrophy or reduction of muscle, causing degenerative changes of muscle functions, appears along with age. Sports training, in which muscle satellite cells are of great importance, is beneficial to increase in muscle mass and improvement of muscle function. 
OBJECTIVE: To summarize regulatory mechanism of satellite cells in skeletal muscle mass; changes of satellite muscle cells in the degenerative process of muscle mass and strength; declining and reverse effects of sports training intervention; situations and problems of current research and prospective of the future. 
METHODS: A computer-based online search was conducted in PubMed database by using the key words of “sarcopenia, skeletal muscle, satellite cells” from 1986 to 2015. The language was limited to English. The eligible papers were further analyzed and reviewed.
RESULTS AND CONCLUSION: A total of 168 papers were screened. Finally, 39 papers were selected according to the titles and objectives. Skeletal muscle atrophy is shown as II type muscle fiber atrophy, and the II type muscle fiber satellite cell content decreases simultaneously. Exercise is beneficial to increase muscle mass and improve muscle function in older people. Both resistance and endurance trainings can increase the skeletal muscle, especially the II muscle fiber satellite cell content with a further increase in the satellite cell activation and proliferation. The number and activation degree of satellite cells are related to muscle aging, and satellite cells and proliferation factors regulate muscle cell formation. Therefore, future researches should not only focus on the increase of satellite cell bank, but also explore effective ways to promote the activation of satellite cells, such as exercise training, nutrition and drugs.
