This post is part of the Run & Reflection series – where I reflect on running, or a completely random topic. Or sometimes, a little bit of both.
In anticipation to the upcoming Ridley Scott directed film, I’ve begun reading The Martian by Andy Weir (and it was only $1.99 on Kindle).
I won’t spoil too much of it for you – but one passage reminded me of the importance of breathing out fully while running:
“After a while, the CO2 (carbon dioxide) absorbers in the suit were expended. That’s really the limiting factor to life support. Not the amount of oxygen you bring with you, but the amount of CO2 you can remove.”
The general idea is in order to get as much oxygen into your lungs as possible, you must rid of as much CO2 as possible. So breathing out is as important as breathing in. Keep that in mind next time you run – trying to push out the CO2.
