Which exercise style builds better muscle blood vessels?
NCT ID NCT07237854
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how two different cycling workouts affect the tiny blood vessels in muscles. Twenty-five healthy but inactive adults did either steady cycling or short bursts of hard cycling. Researchers took small muscle samples and measured oxygen use to see which exercise type leads to better blood vessel health.
