Brief Summary
Physical inactivity and protein malnutrition have been implicated to be key and modifiable causes of enhanced muscle mass loss among seniors. However, the individual benefit, as well as the additive or possibly interactive benefit of exercise and Protein supplementation on fall prevention has yet to be confirmed in a large clinical trial. This study aims to test the individual and combined effect and cost-effectiveness of a simple home exercise program and / or protein supplementation on the risk of falling in seniors at high risk of progressive muscle mass loss and sarcopenia.

Study Arms (4)
Protein Supplement plus Active Exercise
ACTIVE COMPARATORParticipants will ingest twice daily 23.7 g of L-leucine-enriched whey protein isolate powder (equivalent to 20 g of Protein) and perform a simple home exercise strength program (3x30 minutes/week)
Protein-free Supplement plus Active Exercise
ACTIVE COMPARATORParticipants will ingest twice daily 23.7 g of a protein-free, isocaloric powder blend and perform a simple home exercise strength program (3x30 minutes/week)
Protein Supplement plus Control Exercise
ACTIVE COMPARATORParticipants will ingest twice daily 23.7 g of L-leucine-enriched whey protein isolate powder (equivalent to 20 g of Protein) and perform a joint flexibility home exercise program (3x30 minutes/week)
Protein-free Supplement plus Control Exercise
SHAM COMPARATORParticipants will ingest twice daily 23.7 g of a protein-free, isocaloric powder blend and perform a joint flexibility home exercise program (3x30 minutes/week)
Interventions

Predosed protein-free powder; can be added to various dishes and drinks
Program includes five strength exercises that can be easily performed at home
Program includes five flexibility exercises that can be easily performed at home
Eligibility Criteria
You may qualify if:
- At least 1 of 5 frailty criteria, definition by Linda Fried: 1) weight loss of \> 4.5 kg in the last 12 months; 2) reduced grip strength in Martin Vigorimeter test: ♂ ≤ 64 kPa, ♀ ≤ 42 kPa; 3) standardized question on exhaustion as published by Fried et al.; 4) gait speed \< 1 m/s; 5) 6-minute walk test \< 300 meters and/or Injurious (any injury) low trauma fall in the last 12 months prior to enrollment
- Reduced protein intake defined as a score ≤ 0.5 at item K of the Mini Nutritional Assessment (MNA)
- Community-dwelling or assisted living
You may not qualify if:
- Mini-mental state examination (MMSE) \< 24 (inability to follow the study procedures and give written informed consent)
- Inability to come to the trial centers
- Inability to walk at least 3 meters with or without walking aid
- Severe kidney impairment (Glomerular filtration rate \[GFR\] \< 30 ml/min)
- Inability to follow exercise instruction or inability to take protein powder mixed in drink or food (test at baseline screening examination)
- Severe gait impairment or diseases with a risk of recurrent falling (due to conditions such as, e.g. Parkinson's disease/syndrome, Hemiplegia after stroke, symptomatic stenosis of the spinal canal, polyneuropathy, epilepsy, recurring vertigo, recurring syncope)
- Major visual or hearing impairment or other serious illness that would preclude participation (e.g. alcohol abuse, alcoholic disease)
- Inability to read/speak/write in German (necessary to follow instructions incl. STRONG exercise manual)
- Living in a nursing home
- Contraindication to treatment (e.g. allergy)
- Contraindication to the vitamin D standard of care therapy
