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 .
Little effect of physical training on body composition and nutritional intake following colorectal surgery—a randomised placebo-controlled trial
Objective : Postoperatively patients have a reduction in nutritional intake and body weight . We studied the effect of postoperative physical training on nutritional intake and body composition . Methods : Patients ⩾60 y admitted for elective colorectal surgery were  r and omised to train muscular strength ( group A ) or to nonstrengthening exercises ( group B ) for 3 months  . Fat mass ( FM ) and lean body mass ( LBM ) were assessed with bioimpedance preoperatively , 7 , 30 , and 90 days postoperatively . Nutritional intake was registered in a sub population . Results : Of 119 included patients , 60 were r and omised to group A and 59 to B. The changes in LBM at postoperative day 7 were a mean ( s.d . ) of 0.4 ( 2.1 ) kg in group A compared to −0.7 ( 2.0 ) kg in B. The difference between groups of 1.2 ( 0.5 ) kg at day 7 was statistically significant ( P=0.03 ) . At no other time was observed difference between groups in weight , LBM , or FM . The energy and protein intake rose during postoperative day 1–7 and rose further after discharge . At no time were differences between groups . Conclusion : Physical training had little effect on body composition following abdominal surgery . The nutritional intake in well-nourished patients did not increase by training
