Abstract:
BACKGROUND:Sarcopenia is the muscle loss in the elderly with aging, and it is closely related to the
degradation of muscle function in the elderly. The research on the mechanism of sarcopenia as wel as effect of movement intervention is developed.
OBJECTIVE:To summary the mechanisms of sarcopenia cel level as wel as the effect of movement intervention.
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
“sarcopenia, muscle, resistance training, aging, protein metabolism”. The literatures on sarcopenia, protein
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.
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
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
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.
