Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1. standard treatment and no supplementation for 12 months

Arm 2. standard treatment and milk protein supplementation of 20 grams (50% whey) twice a day for 12 months. The protein supplementation will be given in a form of 250 ml x 2 strawberry flavoured beverage and it contains 70 kcal/100ml of energy.

Arm 3. standard treatment and isocaloric placebo supplementation twice a day for 12 months. The isocaloric placebo supplementation will be given in a form of 250 ml x 2 strawberry flavoured beverage and it contains 1 g/100ml milk proteins (20% whey) and 70 kcal/100ml of energy.

Standard treatment will include: a) instructions to perform twice a day 10-30 min home based unsupervised simple exercises (chair rise, steps, etc.), b) instructions to eat proteins on every meal from different protein sources of regular foods, and c) instructions to use vitamin D3 supplementation with a dose of 20 ug/d. The compliance to all treatments is up to the participants themselves and the compliance is followed by daily written patient diaries that are collected every three months.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The patients will be randomized into three arms by computer generated random numbers. The content of the supplement (protein vs. isocaloric placebo) will be randomized off-site by staff not belonging to the research group and kept sealed until the analysis of 12-month endpoints.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A list of 100 sets of numbers 1, 2, and 3 in random order are computer-generated to indicate each treatment.
Masking / blinding
Blinded (masking used)

Summary
Brief summary
Age related muscle loss i.e. sarcopenia is a common health problem among older people and physical exercise and dietary protein has been emphasized in prevention and treatment of sarcopenia. Rigorous trials investigating effects of protein supplementation on physical performance in sarcopenic populations are still scarce. The aim of this study is to investigate the effects of protein supplementation along with simple home-based exercises on physical performance among home-dwelling sarcopenic older people. During 2012 the entire 75+ population (N = 3275) living in Porvoo, Finland will be approached by a postal questionnaire and persons at risk of sarcopenia are further screened for this randomized controlled trial.
