Hypothesis
Can whey protein supplementation improve functional recovery in older adults post-hospitalization?
Conclusion
The study found that while whey protein supplementation was feasible, it did not show statistically significant improvements in physical function or body composition.
Supporting Evidence
- 116 subjects were enrolled in the study.
- Retention rate was 76.8%.
- Adherence rates were around 58.5% for maltodextrin and whey protein.
- Data collection feasibility rates were moderate to high.
Takeaway
Older adults who were hospitalized might benefit from whey protein, but this study showed it didn't make a big difference in how well they moved or their body composition.
Methodology
A pilot randomized-controlled trial with subjects aged 65+ recruited from a hospital, randomized into three supplementation groups.
Limitations
The study had slow recruitment, low adherence, and moderate retention rates.
Participant Demographics
Subjects were older adults aged 65 and above.
