Breathing exercises to help children with obesity and asthma

This trial is testing whether inspiratory muscle rehabilitation—special breathing exercises using a device called the PrO2—can help children who have both obesity and asthma. The study compares children who use the PrO2 device with real breathing resistance against a control group using the same device with less resistance. Researchers hope this treatment will reduce asthma symptoms and improve breathing in children who haven't responded well to standard asthma medicines alone.

Many children with both obesity and asthma have symptoms that don't improve even with typical asthma medications. Scientists believe the problem may not just be inflammation in the airways, but also weakness in the breathing muscles themselves. This trial is testing whether strengthening those muscles through targeted breathing exercises could help these children breathe easier and have fewer asthma problems.
