What is one effect of diaphragmatic breathing on the ribcage during inhalation?

Diaphragmatic breathing has a significant impact on the ribcage during inhalation by enhancing the alignment of the ribcage over the pelvis. When you engage in diaphragmatic breathing, the diaphragm contracts and moves downward, creating negative pressure in the thoracic cavity. This allows the lungs to expand more fully, which in turn encourages the ribcage to move outward and upward in a way that promotes better alignment.

This improved alignment supports proper posture and overall biomechanics. A well-aligned ribcage helps ensure that the pelvis is also positioned correctly, which is essential for maintaining an effective and balanced movement pattern. By promoting this alignment, diaphragmatic breathing not only aids in efficient respiration but also contributes to stability and support for the spine and surrounding musculature.

The other options do not accurately reflect the physiological responses associated with diaphragmatic breathing. Instead of collapsing or restricting movement, diaphragmatic breathing facilitates optimal expansion and alignment, which is crucial for both breathing efficiency and postural integrity.
