Hi! Thanks for making these forums available, I’ve learned a ton just rifling through these.
I was hoping to ask a question regarding heart rate drift and AeT. When I began reading the training bible that is Training for the Uphill Athlete I did the treadmill test (breathing through the nose) to determine the ballpark of my AeT. After reading some of the comments I began to doubt whether or not my AeT really was the 158bpm that I had calculated from the treadmill. I sort of put myself in the ADS category and then read that those individuals can potentially breathe through their noses above AeT. So I did the heart rate drift test this morning, as advised, on a relatively flat loop for about an hour. Training peaks calculated the Pa:Hr (according to the app on my phone) at 1.6% which hints that I was correct about my AeT? My question is, as the calculation is a simple ratio is it possible that I am above my AeT but simply running at a constant pace/HR so the ratio is good? Is it possible to be above AeT but still get a Pa:Hr below 5% ?
It’s not that I don’t think it’s impossible for me to have this AeT, I just want to be sure I’m getting the most out of my training! Thanks so much for reading!
