NCT ID NCT07571720
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether plant-based protein (soy and rice) works as well as animal-based protein (whey) for building lean muscle in 25 elite male youth soccer players aged 16-18. Over 4 weeks, players took a protein drink after training. Researchers measured changes in fat-free mass using body scans and other methods.
