The Claim
Impaired insulin-mediated microvascular perfusion in skeletal muscle is associated with obesity, insulin resistance, and ageing in both animal models and humans, and this vascular dysfunction may precede the development of myocyte-level insulin resistance.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When the tiny blood vessels in muscles don't respond well to insulin, it's linked to being overweight, having insulin resistance, and getting older — and this might actually happen before the muscle cells themselves become resistant to insulin.

What the research says
1 studyStudy: Muscle microvascular blood flow responses in insulin resistance and ageing
The study shows that when tiny blood vessels in muscle don’t respond well to insulin, it can lead to insulin resistance, especially in older people or those with obesity, which matches the claim.
