In conclusion , decrease in muscle strength and muscle mass in older patients is dependent on the type of admission .
HIGHLIGHTSPhysical inactivity during hospitalization is associated with detrimental outcome .Muscle strength and muscle mass decreased in electively admitted older patients .Muscle strength and muscle mass did not change in acutely admitted older patients
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 .
Bed rest promotes reductions in walking speed, functional parameters, and aerobic fitness in older, healthy adults.
CONTEXT The exact relationship between the bed rest-induced loss of skeletal muscle and reductions in muscle strength and physical performance in the older individuals is still unclear . OBJECTIVE We examined the effect of 10 days of bed rest on changes in regional body composition , muscle strength , and functional status , and the relationship between these variables in older individuals . DESIGN , PARTICIPANTS , AND INTERVENTION Regional body composition was measured using dual energy x-ray absorptiometry . We also determined changes in leg strength and several indices of functional status , including walking speed . RESULTS Body weight , body mass index , and total and lower extremity lean mass decreased with bed rest . There were also significant reductions in knee extension one repetition maximum , isometric knee extension , knee extension 60 ° concentric , stair ascent time , stair ascent power , stair descent time , VO2 max , floor transfer test , 5-minute walk time , and chair st and . The overall change in total and lower extremity lean mass was also directly related to bed rest-induced reductions in one repetition maximum knee extension . CONCLUSIONS Bed rest promoted overall declines in muscle mass , muscle strength , and physical function in older individuals . The changes in lean tissue were closely correlated with the bed rest-induced decline of muscle strength
