Scientists compare High-Intensity workouts to find the best for your heart
NCT ID NCT07180550
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how different types of exercise—like high-intensity interval training (HIIT) and functional training—affect heart rate, breathing, and muscle recovery right after a workout. Researchers will monitor 27 healthy, active adults before and after exercise sessions. The goal is to understand which workout style is most efficient, which could help design better exercise plans for people with health conditions.
