CAN SITTING WITH POOR POSTURE EFFECT YOUR BREATHING?
The answer is yes. This study showed pelvic position could effect how well a person can fill their lung while breathing.
The study showed as a person posture become less optimum, there lungs did not fill as well.
The upper thoracic spine level showed increased anterior tilting at 10–30° posterior pelvic tilt sitting. This was measured (spirometry) with a device that measure how much air is expelled during a cycle of breathing.
Respiratory Function using spirometry was significantly reduced at 30° posterior pelvic tilt sitting. Also know as sitting in a slouched posture. Than at 0° posterior pelvic tilt sitting. Sitting up straight.
The authors posit that respiratory impairment may be due to changes in rib angles in PPTS which restrict thoracic excursion during respiration as well as compression of internal organs and resulting restriction of diaphragm motion.
