The Claim
Twelve weeks of blood flow restriction training at 70% arterial occlusion pressure increases insulin sensitivity by 25% in overweight and obese older women, as measured by HOMA-IR.
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 overweight and obese women over 60, 12 weeks of blood flow restriction training at 70% arterial occlusion pressure increases insulin sensitivity by 25%, as measured by HOMA-IR.
See the scientific wording
Twelve weeks of blood flow restriction training at 70% arterial occlusion pressure improves insulin sensitivity by 25% in overweight and obese older women, as measured by HOMA-IR, suggesting this modality may help reduce metabolic disease risk.
Tight bands around the legs during light exercise block blood flow out of the muscles, causing buildup of metabolic byproducts. This triggers muscle growth and reduces chronic inflammation. Larger muscles absorb more sugar from the blood, and lower inflammation allows insulin to work better, so blood sugar levels drop.
What the research says
1 studyIn a study, older women who did light weight training with a tight band around their legs for 12 weeks saw their body’s ability to use insulin improve by exactly 25%, which is what the claim said would happen.
