This is for two reasons: 1) the abdomen is compressed during the twist which means it cant push out as easily or at all; this means that the ribs need to move more during the act of inhalation, 2)the rib cage itself is under more pressure, it is loaded with tension from being stretched in the twist; this makes it harder for the ribs to separate and allow air in.

The diaphragm, also known as the thoracic diaphragm, is a large structure located at the bottom of the thoracic cavity that facilitates the breathing process. The contraction and relaxation of the diaphragm creates alternating pressure between the abdominal and thoracic cavities. Because air will always move from the highest pressure area to the lowest pressure area. The diaphragm completely separates these two cavities and keeps individual structures from travelling between compartments.
