Measurement of the Diaphragm Loading During the Training With a IMT Device

This study is measuring how much work the diaphragm (the main breathing muscle) does at different resistance levels during inspiratory muscle training (IMT), a type of breathing exercise therapy. IMT devices are commonly used to strengthen breathing muscles, but it is not fully understood how much the diaphragm specifically is contributing versus other muscles. You may be eligible if you are a healthy adult over 18 without anticoagulation therapy, esophageal lesions, or airway problems. Participation involves having small pressure-measuring tubes (catheters) placed in your esophagus and stomach while you breathe through an IMT device at varying resistance levels, during a single session. This summary was prepared using AI to help patients understand this research.
