The Claim

Twelve weeks of supervised exercise therapy significantly reduces mRNA expression of polymorphonuclear elastase by 48% and myeloperoxidase by 39% in peripheral blood mononuclear cells of patients with symptomatic peripheral artery disease, independent of changes in walking ability or muscle power.

How it works
1 study reviewed
In plain English

In patients with symptomatic peripheral artery disease, 12 weeks of supervised exercise therapy reduces the levels of two inflammatory markers—polymorphonuclear elastase and myeloperoxidase—in blood cells, regardless of whether walking ability or muscle strength improves.

See the scientific wording

Supervised exercise therapy for 12 weeks significantly reduces mRNA expression of polymorphonuclear elastase by 48% and myeloperoxidase by 39% in peripheral blood mononuclear cells of patients with symptomatic peripheral artery disease, independent of improvements in walking ability or muscle power, suggesting a direct association between exercise and systemic inflammatory marker reduction.

Why this might work

Regular physical activity reduces the activity of immune cells called neutrophils, causing them to produce less of two inflammatory proteins inside their genetic code, even when muscle strength and walking ability do not improve.

    After 12 weeks of supervised exercise, people with leg artery disease had lower levels of two key inflammation proteins in their blood—even if their walking didn’t get better. This suggests exercise fights inflammation in a way that’s separate from just making muscles stronger.
