What does this rating mean?
A solid systematic review with caveats, or consistent indications with a limited scope.
Findings
The effect of whey protein on sarcopenia in older adults, with and without concurrent strength training.
Who this applies to
Older adults diagnosed with sarcopenia (age-related muscle loss), living at home or in hospital.
Size of the research
Ten randomised trials with 1154 participants in total.
What to keep in mind
The number of studies is limited. The authors say more research is needed to confirm the result, especially for the combination with strength training.
Practical conclusion for REZA
Confirms that supplementation without training delivers considerably less than the combination.
