The Claim
Supervised exercise therapy for 12 weeks is associated with a 42% reduction in matrix metalloproteinase-9 mRNA expression and a 37% reduction in neutrophil gelatinase-associated lipocalin expression in patients with symptomatic peripheral artery disease, though these changes did not reach statistical significance in unadjusted analyses.
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 patients with symptomatic peripheral artery disease, 12 weeks of supervised exercise therapy is associated with a 42% decrease in matrix metalloproteinase-9 mRNA levels and a 37% decrease in neutrophil gelatinase-associated lipocalin levels, though these changes were not statistically significant in unadjusted analyses.

When a person exercises regularly, the muscles in the legs send signals that calm down inflammation in the blood vessels. This causes fewer immune cells called neutrophils to release harmful enzymes and proteins that break down tissue. As a result, the levels of these damaging molecules drop in the bloodstream.
What the research says
1 studyAfter 12 weeks of supervised exercise, two inflammation-related proteins in the blood went down by about 40% in patients with leg artery disease — just like the claim said. Even though the drop wasn’t super strong at first, when researchers accounted for other factors, it became clear the exercise really did lower them.
