BREATHWORK FOR DIAPHRAGM STRENGTHENING

WHY THIS WORKS

During expiration, the diaphragm is relaxed, giving it its classic dome shape; elastic recoil of the thoracic wall causes the thoracic cavity to contract, forcing air out of the lungs.

 

During inhalation, the diaphragm contracts and thickens, its centre moves downward and the dome shape flattens thereby pulling air into the lungs. The change in diaphragm amplitude during the breathing cycle, measured by using ultrasound imaging, is a measure of diaphragm strength.
