Can a breathing exercise boost Smokers' muscle strength?
NCT ID NCT07200895
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at how a single session of breathing muscle training affects vital signs and muscle strength in 34 young male smokers aged 18-25. Participants did breathing exercises at either 30% or 60% of their maximum effort. The goal was to see if the training could temporarily improve breathing and handgrip strength.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Inspiratory muscle training device
- What this could lead to
- If successful, this could point toward a simple breathing exercise to improve respiratory and peripheral muscle strength in smokers.
- What could go wrong
- This is a small, single-session study in healthy young men, so results may not apply to older smokers or those with lung disease. Long-term benefits are unknown.
