Stair snacks: tiny workouts, big heart gains?
NCT ID NCT07558421
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether brief, intense stair-climbing sessions (called 'exercise snacks') can improve blood vessel function and body composition in overweight adults aged 18-35. Sixty participants will be split into four groups, including a no-exercise control group, for 6-8 weeks. Researchers will measure changes in artery health, body fat, and blood lipids.
