Does anyone else suffer from oxygen debt after tumble turn?
Former Member
This is not the least of my worries in swimming, but I tend to fall into oxygen debt after tumble turns. In fact, when I keep doing tumble turns in lap swims, it is less taxing to swim 50 LCM than 25 SCY, because I have more time in 50 LCM to recover from the oxygen debt, whereas in 25 SCY, I have to do another tumble turn and fall, yet again, into oxygen debt, before fully recovering from the previous bout.
Do other master swimmers out there suffer from a similar problem? How do you over come this?

It is not a mind game, or anything of the type, it is CO2 excess. Tthe time it takes to turn allows an increase in the partial pressure of CO2 in your blood stream because you are not ventilating and blowing it off. This subsequently decreases the partial pressure of O2 in your blood because it binds to hemoglobin to deliver O2 to your tissues that are working hard and burning glucose.
The problem lies in the fact that you are making tons of CO2, if you aren't blowing it off you feel like you need to take a breath, thanks to the lovely chemoreceptor in the medulla. CO2 is the trigger to make you breath, not O2 debt, unless you have COPD.
