Simple bike test could catch Athletes' hidden artery blockage
NCT ID NCT05229250
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a non-invasive cycling test, combined with a muscle oxygen monitor (NIRS), could detect a condition called flow limitation in the iliac artery (FLIA) in endurance athletes. FLIA can cause leg pain and limit performance, and early detection is difficult. Researchers compared trained cyclists with FLIA to healthy cyclists, measuring muscle oxygen and power output during exercise. The goal was to see if this simple test could help screen athletes at risk.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could lead to a simple, non-invasive screening test to catch leg artery problems early in athletes, preventing serious injury.
What could go wrong
This is a small, early exploratory study that was terminated, so results may be limited. The test may not prove accurate enough for widespread use.
