ABSTRACT Hospitalization may induce a decrease of muscle strength and muscle mass in older patients due to physical inactivity , malnutrition and diseases , negatively affecting health outcome .
We aim ed to examine the literature on change in muscle strength and muscle mass in older patients during hospitalization .
EAA supplementation to increase nitrogen intake improves muscle function during bed rest in the elderly.
BACKGROUND & AIMS Older individuals are more likely to experience extended hospitalization and become protein malnourished during hospitalization . The concomitant compulsory inactivity results in functional decline . Increasing protein intake in hospitalized patients improves nitrogen balance , but effects on function are unknown . In the present study , we examined the effects of increasing protein intake by essential amino acid ( EAA ) supplementation in older individuals subjected to 10 d bed rest on LBM and muscle function . METHODS Subjects were given a placebo ( n=12 , 68+/-5 ( SD ) yrs , 83+/-19 kg ) or 15 g of EAA ( n=10 , 71+/-6 , 72+/-8 kg ) 3 times per day throughout 10d of bed rest . LBM , muscle protein synthesis , and muscle function were determined before and after bed rest . Due to an imbalance in r and omized gender distribution between groups , gender and beginning functional and LBM measures were utilized for analyses by repeated measures analysis of covariance ( RMANCOVA ) . RESULTS Analyses revealed the potential for the preservation of functional outcomes with EAA supplementation . CONCLUSIONS Increasing protein intake above the RDA may preserve muscle function in the elderly during compulsory inactivity . EAA supplementation is potentially an efficient method of increasing protein intake without affecting satiety
