Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Participants (n = 137) will be community-dwelling older adults. After a pre-participation screening participants will be distributed randomly but stratified by sex and age to one of the 3 groups (low protein + strength training, high protein + strength training, low protein and no strength training(=control)). Study participants are eligible if they are male or female with an age between 65 and 85 years and if their cognitive status as well as their physical fitness level allows to participate at the strength training sessions. Exclusion criteria comprise chronic diseases which contraindicate the training sessions, serious cardiovascular disease, diabetic retinopathy and manifest osteoporosis, a frailty index at or above 3, medication with anticoagulants or cortisone drugs and also regular strength training during the last six months.
Primary outcome measure is the change in the Chair Stand Test. Secondary outcome measures comprise anthropometric data, functional performance tests, immunological and oxidative stress parameters, microbiota, metabolomics, proteomics and the nutritional status.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Strength Training and Protein high
6 weeks of high protein intake (additional 1g/kg bw/d) followed by a 8 weeks resistance training (Progressive strength training in a fitness center is applied; the intensity is adjusted continuously in order to obtain a sufficient training stimulus). During the training period the protein intake remains.
High protein intake
6 weeks of high protein intake mainly via food (additional 1g/kg bw/d) followed by a 8 weeks resistance training (Progressive strength training in a fitness center is applied; the intensity is adjusted continuously in order to obtain a sufficient training stimulus). During the training period the protein intake remains.
Strength training
6 weeks of different protein intake followed by a 8 weeks resistance training (Progressive strength training in a fitness center is applied; the intensity is adjusted continuously in order to obtain a sufficient training stimulus). During the training period the protein intake remains
Strength Training and Protein low
6 weeks of low protein intake (1g/kg bw/d) followed by a 8 weeks resistance training (Progressive strength training in a fitness center is applied; the intensity is adjusted continuously in order to obtain a sufficient training stimulus). During the training period the protein intake remains.
Low protein intake
6 weeks of low protein intake (1g/kg bw/d) followed by a 8 weeks resistance training (Progressive strength training in a fitness center is applied; the intensity is adjusted continuously in order to obtain a sufficient training stimulus). During the training period the protein intake remains
