There are many factors that can result in both faulty respiration and poor posture including poor exercise tolerance (being “out of shape”), dyspnea (shortness of breath), poor chest expansion, poor neuromuscular control of core and pelvic floor muscles, diaphragm issues (hernia, muscle shortness, poor pressure output), increased lumbar lordosis, and low back pain. This is because several of the muscles that help control posture and stabilize the core—such as the thoracic diaphragm, transverse abdominus, and the pelvic floor muscles—are also involved in the breathing process.
One of the most critical and overlooked factors is the ability to maintain an optimal zone of apposition (ZOA) of the diaphragm. This refers to the dome, or “umbrella” part, of the diaphragm and its attachments to the lower rib cage. The ZOA is important because it is largely controlled by the abdominal muscles and plays a role in how much air you can take in while breaking, or maximal respiration.
