The Claim
When you do heavy lifting while restricting blood flow to your muscles, your muscles feel more burned and stressed during the workout than when you lift heavy without restricting blood flow.
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.
When you do heavy lifting while restricting blood flow to your muscles, your muscles feel more burned and stressed during the workout than when you lift heavy without restricting blood flow.
See the scientific wording
High-load resistance training with blood flow restriction induces significantly higher acute metabolic stress, as measured by greater increases in deoxyhemoglobin and total hemoglobin during training, compared to high-load resistance training without restriction.
What the research says
1 studyThe study found that when people lifted heavy weights while restricting blood flow to their muscles, their muscles showed much bigger changes in blood oxygen levels — meaning more stress — than when they lifted the same weights without restricting blood flow.
