Life is an ultramarathon

This is the V0₂max reading I got from the sensor after a bit of noise removal. In other words, the amount of oxygen that each kilo of my body can metabolise in a minute (in millilitres). This is about 5 litres per minute in total. That's a bit higher than I expected, but I'm not sure how accurate this is as we're still novice in using this system, and the output was a bit noisy.

I started to run on the treadmill at 12km/h, then increased the speed by 2km/h every 2 minutes and stopped at 18km/h. In this kind of test, you're supposed to reach a plateau in the measured V0₂, and that is your actual V0₂max. I didn't reach such a plateau and was stopped by difficulty to breathe in the mask. This is somehow a known effect: The Great VO2 max Myth.


This is quite an interesting and fun measurement to take, but I've got the feeling that the results aren't of the highest reliability. It seems highly dependent on your mood of the day and how keen you are to push it. Let alone the 5 calibration stages involving a specific gas mix, a 3 liter syringe and breathing in tempo with fast beeps.

Ultra measure.
