Core workouts may help heavy smokers breathe easier
NCT ID NCT07241624
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether isometric (static) or isotonic (dynamic) trunk exercises better improve lung function in heavy smokers. 90 smokers aged 20-45 who smoked at least 20 cigarettes daily did either planks and static bridges or sit-ups and Russian twists three times a week. The goal was to see if strengthening core muscles could help breathing.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- trunk muscle strength training (isometric and isotonic exercises)
- What this could lead to
- If successful, this could point toward a simple exercise program to help heavy smokers improve their lung function.
- What could go wrong
- This is a small, completed study with no phase designation. The results may not apply to all smokers, and exercise alone cannot reverse smoking damage.
