so we're at one of our pregnancy classes last night and they stressed deep, even breathing to push oxygen further into the lungs, control heartrate as reasonably as possible, control pain, etc. I'm thinking, "how is this new? In ever sport I've participated in, this is what I was taught and how I survived." Come to find out, Lamaze technique stresses shallow, quick breathing. So, my question is... is there any sport, activity, pain management, whatever where there is value to quick, shallow breaths? What am I missing (since that's a popular technique and maybe I can apply it in some fashion with cycling or something)?
