The Claim
Handgrip strength increases modestly over a 12-week period in healthy older adults, irrespective of protein supplementation, with non-intervention factors such as repeated testing or seasonal variation contributing to the observed change.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In healthy older adults, handgrip strength increases slightly over 12 weeks even without protein supplements, and this change is likely due to factors like repeated testing or seasonal changes.
See the scientific wording
Handgrip strength increases modestly over 12 weeks in healthy older adults regardless of protein supplementation, suggesting non-intervention factors such as repeated testing or seasonal variation may influence outcomes.
Repeating the handgrip test trains the brain and muscles to work together more efficiently, making the grip stronger without needing more muscle size or protein.
What the research says
1 studyEven without drinking extra protein shakes, older adults in the study got a little stronger in their grip over 12 weeks—probably because they got better at the test itself, not because of what they ate.
