Abstract:

BACKGROUND: Elderly muscle protein metabolism appears negative balance status, which is considered to be the main reason for elderly muscle loss and muscle function decline. In recent years, many studies have confirmed that resistance training and protein supplements can effectively improve the phenomenon of the negative balance of the elderly muscle protein metabolism, increase the elderly muscle mass, and improve muscle function.
OBJECTIVE: To review the effect of the elderly resistance training, protein supplement and resistance training combined with protein supplements on muscle protein metabolism and muscle function, and to explore possible ways to improve the elderly muscle function and inhibit muscle loss.
METHODS: The CNKI database (2005-01/2012-12) and PubMed database (2010-01/2012-12) were retrieved by the computer for the literatures addressing muscle protein metabolism and the effect of protein supplements and resistance training on muscle protein metabolism in the elderly. The key words were “protein metabolism, muscle cells, muscle loss, resistance training, protein supplement” in Chinese and “muscle cell, resistance training, sarcopenia, protein metabolism” in English.
RESULTS AND CONCLUSION: A total of 81 literatures were screened out, 22 literatures that did not meet the standards were eliminated, and then finally 59 literatures were included for the analysis and review. The results show that the negative balance of elderly muscle protein metabolism is the direct reason to elderly muscle loss. Resistance training and leucine-rich protein supplement can effectively enhance the the elderly muscle protein anabolism level, and improve muscle function of the elderly. But the elderly muscle protein anabolic response capability against resistance training and protein supplements is much lower than young people.
