Sarcopenia, exercise and muscle reconstruction
Zhu Zhi-feng
Abstract： BACKGROUND:Sarcopenia is the muscle loss in the elderly with aging, and it is closely related to the <br> degradation of muscle function in the elderly. The research on the mechanism of sarcopenia as wel as effect of movement intervention is developed. <br> OBJECTIVE:To summary the mechanisms of sarcopenia cel level as wel as the effect of movement intervention. <br> METHODS:A computer-based retrieval was conducted on CNKI database and PubMed database for literatures on sarcopenia and elderly resistance training from January 2000 to December 2012. The key words were <br> “sarcopenia, muscle, resistance training, aging, protein metabolism”. The literatures on sarcopenia, protein <br> metabolism and resistance training were included, and the obsolete and repetitive literatures and the literatures lack of credibility were excluded. Final y, 58 literatures were included for analysis. <br> RESULTS AND CONCLUSION:Resistance training can inhibit sarcopenia to a certain extent, so that to increase muscle mass in the elderly and promote the recombinant of motor units. But the recombinant is limited to the <br> mutual conversion between the type Ⅱa and Ⅱb fibers. Resistance training combined with protein supplement can effectively promote elderly muscle reconstruction;the elderly muscle anabolic response confrontation <br> reaction after resistance training is slower than young people, but the inflammatory response after training is stronger than younger people. However, Omega-3 has a good effect on the elimination of such inflammatory response.
