Breathing training may boost fitness in teens with learning disabilities
NCT ID NCT07787546
First seen Aug 26, 2026 · Last updated Sep 01, 2026 · Updated 3 times
Summary
This trial tests whether a 12-week program of respiratory muscle training—using a device that strengthens breathing muscles—combined with exercise can improve lung function and exercise tolerance in obese adolescents aged 10 to 16 who have specific learning disabilities. Half of the 44 participants will receive this training, while the other half will follow a different exercise routine. Researchers will measure changes in breathing strength, lung function, walking ability, and related factors to see if the training offers extra benefits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Respiratory muscle training using a breathing exercise device (POWERbreathe) combined with exercise
- What this could lead to
- If effective, this approach could offer a simple, drug-free way to improve breathing and physical fitness in obese adolescents with learning disabilities, potentially enhancing their daily function and quality of life.
- What could go wrong
- The trial is small (44 participants) and early-stage, so results may not apply broadly. The training requires regular supervision and may be challenging for some teens, and benefits might be modest or short-lived.
