The Claim
In obese adults, skeletal muscle perfusion during insulin stimulation is significantly reduced at rest compared to lean adults, and a single bout of isometric exercise fully restores this perfusion to levels observed in lean adults.
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 obese adults, blood flow to skeletal muscles during insulin stimulation is lower at rest than in lean adults, but one session of isometric exercise restores blood flow to the level seen in lean adults.
See the scientific wording
In obese adults, skeletal muscle perfusion during insulin stimulation is significantly reduced at rest compared to lean adults, but this deficit is fully restored by a single bout of isometric exercise, demonstrating that impaired blood flow is a reversible component of insulin resistance.
When a person does a short bout of muscle squeezing exercise, the muscles demand more oxygen and energy, which causes blood vessels to widen. This lets more blood flow into the muscle, bringing more glucose with it. In obese people, this blood flow is normally low when insulin is present, but the exercise fixes it completely, so glucose delivery returns to normal levels even though the muscle still struggles to use the glucose properly.
What the research says
1 studyIn obese people, insulin doesn’t bring enough blood to muscles like it does in lean people, but one workout fixes that blood flow problem — even if the muscles still don’t use sugar perfectly. So the poor blood flow isn’t permanent.
