- Background Loss of muscle mass is common among old people living in institutions but trials that evaluate interventions aimed at increasing the muscle mass are lacking. Objective, participants and intervention This randomized controlled trial was performed to evaluate the effect of a high-intensity functional exercise program and a timed protein-enriched drink on muscle mass in 177 people aged 65 to 99 with severe physical or cognitive impairments, and living in residential care facilities. Design Three-month high-intensity exercise was compared with a control activity and a protein-enriched drink was compared with a placebo drink. A bioelectrical impedance spectrometer (BIS) was used in the evaluation. The amount of muscle mass and body weight (BW) were followed-up at three and six months and analyzed in a 2 × 2 factorial ANCOVA, using the intention to treat principle, and controlling for baseline values. Results At 3-month follow-up there were no differences in muscle mass and BW between the exercise and the control group or between the protein and the placebo group. No interaction effects were seen between the exercise and nutritional intervention. Long-term negative effects on muscle mass and BW was seen in the exercise group at the 6-month follow-up. Conclusion A three month high-intensity functional exercise program did not increase the amount of muscle mass and an intake of a protein-enriched drink immediately after the exercise did not induce any additional effect on muscle mass. There were negative long-term effects on muscle mass and BW, indicating that it is probably necessary to compensate for an increased energy demand when offering a high-intensity exercise program.

- OBJECTIVES: To evaluate whether age, sex, depression, dementia disorder, nutritional status, or level of functional balance capacity influences the effect of a high-intensity functional weight-bearing exercise program on functional balance.DESIGN: Preplanned subgroup analyses of a randomized controlled trial.SETTING: Nine residential care facilities.PARTICIPANTS: One hundred ninety-one people aged 65 to 100 dependent in activities of daily living and with Mini-Mental State Examination scores of 10 or greater.INTERVENTION: A high-intensity functional weight-bearing exercise program or a control activity, each comprising 29 sessions over 3 months.MEASUREMENTS: Functional balance capacity was assessed blindly using the Berg Balance Scale (BBS) at baseline, 3 months, and 6 months. The BBS consists of 14 tasks, common in everyday life, such as standing up from sitting and, while standing, reaching forward or turning 360°. Interactions between allocation to activity group and each subgroup were evaluated according to the intention-to-treat principle.RESULTS: The subgroup analyses revealed no statistically significant interaction for age, sex, depression, dementia disorder, nutritional status, or level of functional balance capacity at 3 (P=.65,.65,.51,.78,.09,.67, respectively) or 6 (P=.69,.62,.20,.94,.48,.85, respectively) months. In addition, at 3 and 6 months there was no significant interaction for cognitive level (P=.28,.47, respectively) or number of depressive symptoms (P=.85,.49, respectively).CONCLUSION: Older age, female sex, depression, mild to moderate dementia syndrome, malnutrition, and severe physical impairment do not seem to have a negative effect on functional balance from a high-intensity functional weight-bearing exercise program. Consequently, people with these characteristics in residential care facilities should not be excluded from offers of rehabilitation including high-intensity exercises.
