The Claim
Blood flow restriction training using 40% arterial occlusion pressure with elastic wraps, when combined with high-intensity resistance training, produces muscle hypertrophy comparable to high-intensity resistance training alone in healthy young 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.
Using elastic wraps to partially restrict blood flow during high-intensity weight training can lead to similar muscle growth as high-intensity weight training without wraps in healthy young men.
See the scientific wording
Blood flow restriction training using 40% arterial occlusion pressure with elastic wraps can be safely and effectively combined with high-intensity resistance training to produce muscle hypertrophy comparable to high-intensity training alone in healthy young men.
When you lift heavy weights, your muscles are pulled hard, which tells them to grow. When you also use a tight band to partly block blood flow, your muscles get hot and burn because waste products build up, which also tells them to grow. Together, these two things make your muscles grow just as much as lifting heavy weights alone.
What the research says
1 studyThis study found that using elastic bands to partly block blood flow during leg exercises, even with lighter weights, helped people build muscle just as much as lifting heavy weights alone. So yes, it supports the idea that you can get similar muscle growth with bands and lighter lifting.
