NCT ID NCT06406907
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how a short training method that restricts blood flow to the muscles affects muscle size, strength, and performance in 68 sedentary young men. Participants did exercises with a cuff on their limbs to limit blood flow. The goal was to see if this approach can improve muscle health and function without long workout sessions.
