Can six weeks of breathing training make Kids' lungs stronger?
NCT ID NCT07810361
First seen Sep 09, 2026 · Last updated Sep 10, 2026 · Updated 1 time
Summary
Researchers are testing whether a six-week program of breathing-muscle training combined with high-intensity interval exercise improves diaphragm thickness, lung function, and aerobic fitness in boys aged 10 to 12 with obesity. Fifty boys are randomly assigned to the combined training or to usual activity. The breathing training uses a handheld device that adds resistance as participants inhale, and the exercise sessions alternate short bursts of hard effort with rest.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a six-week program of inspiratory muscle training with a pressure-loading breathing device plus functional high-intensity interval training
- What this could lead to
- If it works, this could offer a low-cost exercise program that helps children with obesity breathe more efficiently and stay active.
- What could go wrong
- The trial is small and short, so any benefits may fade once training stops. Results in boys aged 10 to 12 may not apply to girls or other age groups.
