Diaphragmatic breathing uses which muscle?

• A. Intercostal muscles
• B. Neck muscles
• C. The diaphragm
• D. Abdominal muscles

Answer: (C)

Diaphragmatic breathing centers on the diaphragm, the main muscle of inspiration. When it contracts, it moves downward, expanding the vertical dimension of the thoracic cavity and drawing air into the lungs. This downward pull also makes the abdomen appear to rise as the abdominal contents are displaced, which is why this breathing style is often called belly breathing. The intercostal muscles between the ribs assist with chest expansion but are not the primary driver in diaphragmatic breathing. Neck muscles may act as accessory muscles in heavy breathing, but they are not the main muscle for this technique. Abdominal muscles are more involved in forcing expiration and stabilizing the abdomen rather than initiating the inhalation in diaphragmatic breathing.
