Why did we need to work on breathing again?

So a recent post discussed ways to breathe better while exercising. But did I mention why that might be important?

If you are going to be exercising for more than a couple of minutes, your body needs to get oxygen to the muscles or the muscles will stop working. Just how much oxygen your muscles will use depends on two processes: getting blood to the muscles and extracting oxygen from the blood into the muscle tissue. Your working muscles can take oxygen out of the blood three times as well as your resting muscles. Your body has several ways to increase the flow of oxygen-rich blood to working muscle:
increased local blood flow to the working muscle
diversion of blood flow from nonessential organs to the working muscle
increased flow of blood from the heart (cardiac output)
increased rate and depth of breathing
increased unloading of oxygen from hemoglobin in working muscle
These mechanisms can increase the blood flow to your working muscle by almost five times. That means that the amount of oxygen available to the working muscle can be increased by almost 15 times!*

  1. Don’t you just hate predictive text??? That should have been “insight”! One day I will get the hang of this 👀
