the diaphragm is a pressure device
this is a note meant to discount the strange idea that an inevitable 'pregnancy symptom' is shortness of breath. if you feel short of breath you can do two things:
- train for pregnancy and you will acclimatize (just as one might to altitude)
- decrease the pressure in your abdominal cavity.
the diaphragm is a pressure device. with your powerful transverse abdominus engaged to keep your posture upright while running, they add quite a squeeze to the gut. the pressure applied by an athletic set of abs is necessary for stability and for generating power in your legs and hip flexors, yet a hindrance for your poor diaphragm.
in order to allow that overworked muscle (yes, your diaphragm is also a muscle) to expand fully, take some of the pressure off your belly. you mountain mommas will breathe deeper with the support of a belly band while running. choose your brand, I'm not shilling them. slap one on and breathe a little deeper. ahhh.
