I've been using improper terminology, for clearly "diaphragmatic support"
is a conceptual inaccuracy. Being an exclusively autonomic muscle, the di-
aphragm is beyond our conscious control. What we are really doing during
the process of supporting the air stream is exploiting the diaphragm's auto-
nomic function (of always applying outward force) by manipulating the length
of time that it is allowed to stay expanded, via the abdominal muscles. If
we didn't have abdominal muscles to counteract its autonomic function, the
diaphragm would remain fully expanded forever and we would never be able to
exhale. That would suck.
