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

This study looks at how much effort the diaphragm (the main breathing muscle) exerts when people use an inspiratory muscle training (IMT) device — a tool that makes breathing in harder so the breathing muscles get a workout. Understanding the load placed on the diaphragm could help optimize training programs for respiratory patients and athletes. You may be eligible if: - You are over 18 years old - You are a healthy person with no major breathing or health problems You may NOT be eligible if: - You are on anticoagulation (blood thinning) medication - You have lesions in your esophagus or airways - You have abnormal results on spirometry (lung function) testing Talk to your doctor to see if this trial is right for you.
