The Claim
Six weeks of low-load resistance training with blood flow restriction significantly increases hamstring muscle thickness and stiffness in recreationally trained men.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In recreationally trained men, six weeks of low-load resistance training with blood flow restriction increases the thickness and stiffness of the hamstring muscles.
See the scientific wording
Six weeks of low-load resistance training with blood flow restriction significantly increases hamstring muscle thickness and stiffness in recreationally trained men, demonstrating that muscle hypertrophy and mechanical property changes can occur without high mechanical tension.
When blood flow is restricted during light exercise, waste products build up in the muscle, which signals the muscle to make more protein and stiffen its structure, leading to thicker and stiffer muscle fibers.
What the research says
1 studyThis study found that using light weights with a blood flow cuff on the legs made the hamstrings just as thick and stiff as using heavy weights — meaning you don’t always need to lift heavy to build muscle.
