Foam rolling study reveals sex differences in muscle oxygenation
NCT ID NCT07078448
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at how a single foam rolling session affects oxygen levels in the hamstring muscles of 36 healthy adults with tight hamstrings. Researchers measured muscle oxygen saturation before and after rolling, and also checked flexibility. The goal was to see if men and women respond differently, which could help personalize warm-up routines.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Foam rolling (self-myofascial release)
- What this could lead to
- If successful, this could help tailor foam rolling routines for men and women to improve flexibility and prevent injuries.
- What could go wrong
- This is a small, completed study with only 36 people, so findings may not apply broadly. It only looks at short-term effects from one session.
