Protein pacing may shield Soldiers' muscles during boot camp
NCT ID NCT07438158
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether spreading protein evenly across meals or taking a leucine supplement at breakfast can help tactical athletes (like soldiers) keep muscle and perform better during 8 weeks of hard training. Sixty-nine healthy men aged 18-35 will be assigned to one of three diet plans, all with the same total daily protein. Researchers will measure changes in lean body mass, strength, and markers of muscle damage.
