The Problems with Traditional Diaphragmatic Breathing

Lowering of diaphragm from relaxation of transversus abdominis

With traditional diaphragmatic breathing, one is taught to focus on expanding the lower abdomen at the start of inspiration. This breathing technique actually restricts diaphragmatic breathing, besides causing other problems.

Expanding the lower abdomen at the start of inspiration relaxes the transversus abdominis (deep lower abdominals), resulting in a lowered position of the diaphragm and excessive shortening of the diaphragm (Figure E). This relaxation of the transversus abdominis also increases the compressive stress on the lower back.

YogaBack breathing promotes a spontaneous co-activation of the transversus abdominis and diaphragm. Activation of the transversus abdominis results in a raised position of the diaphragm at the start of inspiration (Figure F). As the diaphragm descends, the transversus abdominis optimizes diaphragmatic breathing by preventing excessive shortening of the diaphragmatic muscle fibers. This inspiratory transversus abdominis muscle activity also improves the diaphragm's ability to lift the lower ribs, thereby expanding the lower rib cage.

This co-activation of the transversus abdominis and diaphragm reduces the fatigue and spinal compression from traditional diaphragmatic breathing. Learning this optimal diaphragmatic breathing technique is effortless with YogaBack's Sacral Support and Lower Thoracic Support.
