I was listening to the latest FLO podcast (only because I was al caught up on the TR podcast of course) and it was a really good one on training/racing at altitude.
One of the things that the special guest Dr. Robert Chapman said was that oxygen saturation during maximal efforts at sea level can be an indicator of how well an athlete will tolerate the change to a higher elevation. Basically using something like a VO2 max test or a ramp test to exhaustion and you look at the O2 saturation during that last minute of effort. Those that are 92% and above seem to not have an easier time making the transition to altitude and those that are under this number have a more difficult transition. I believe his exact words were that under 92% and the altitude is going to kick your butt.
I remember Nate going through all of the prep for proper acclimatization while getting ready for Leadville. There are pulse/ox meters with Bluetooth to android/ios. Seems like it would be a cool feature if you could pair a pulse/ox with trainer road and collect this data. Just another arrow in the quiver and might help folks understand what’s going on if they really struggle with altitude.
Have a great Friday,
