The Pelvic and Respiratory Polar Caps

In our map of the horizontal diaphragms of the body, the respiratory diaphragm is the third horizontal. It correlates with the first two broad, sling-like structures that we have already reviewed—one at the sole of the foot and the other at the pelvic floor. As we have seen, congestion, rigidity, or laxity in any one of these planes can impair movement in the other diaphragms. Since we stand on two legs, our aim in yoga practice is to move from the ground upward, initially gaining elasticity and responsiveness within the plantar fascia at the sole of the foot.

The sphere-like space of the abdomen can be compared to a globe. The northern cap of the globe is the respiratory diaphragm and the southern cap is the perineum. Both structures have central tendons—tough fibrous weaves at the center of the “polar caps” that orient and reinforce the diaphragms. In all yoga postures, we align these two caps in order to facilitate a more prolonged, uninhibited breath. The dynamic tension between these two poles in part determines efficiency in breathing. When the lower pole of the pelvic diaphragm is positioned directly under the upper pole of the respiratory diaphragm, breathing is easier (see B of fig. 5.3). When the two diaphragms are misaligned, the tensions within the pelvic and abdominal cavities compete and breathing may be compromised (see A and C of fig. 5.3).

In haṭha yoga, the compatibility of these two diaphragms is critical, especially during prāṇāyāma when movements within the spine, rib basket, and abdominal muscles are subtle. (I prefer rib “basket” to rib “cage,” for the weave of a wicker basket better resembles the plaiting of intercostal muscles between the ribs.)
