Breathe
Breathing deeply -- in through your nose and out through your mouth -- engages a "relaxation," or "parasympathetic response," which decreases your blood pressure, lowers perceived exertion levels during cycling, improves circulation, lowers your pulse rate, diminishes oxygen consumption and can create a sense of mental and spiritual well-being while on the bike
I don't think they meant that to apply when your say hauling ass in a TT, or trying to climb a 10% grade.
To the extent it diminsihes oxygen consumption, my bet it is do so at the expense of work output.
The only thing I try to think about breathing when I'm really suffering is to exhale fully. The body will take care of the inhale part.
