* The anteroposterior distance (L) of the diaphragm decreases as the angle of posterior tilt of the thoracic spine relative to the lumbar spine increases.
* The shorter the anteroposterior distance (L) of the diaphragm, the greater the upward and downward travel of the diaphragm during breathing, which can increase the volume of thoracic breathing.
* A posterior tilt of the thoracic spine, similar to that of a runner, activates thoracic inspiration by lifting the ribs upward and then downward.
* Moving the thoracic spine backward relative to the lumbar spine reduces the abdominal space, somewhat restricting abdominal breathing.
