Can tightening blood flow boost muscle gains?
NCT ID NCT05863039
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether doing leg strength exercises while restricting blood flow (using a cuff) builds more muscle and strength than regular training. Eight healthy adults completed different types of leg workouts. The goal was to see if blood flow restriction could make low-load training as effective as heavy lifting. Results may help design better exercise programs.
