Hi Reed !
I was thinking …. if 180bpm is AnT then the test has been distorted because once you got to 180 there was no further increase possible.
I’ve seen Scott Semple comment, from time to time, on AeT test questions where he observers that if a test is at or close to AnT HR there’s low drift because AnT HR is a ceiling.
I wonder if in this case hrTSS is actually a better reflection of the actual stress.
The power based TSS for the hour following your warm up is around 45 and doesn’t vary much between the first and second 30 mins.
But by HR measurement you were close to 180bpm (AnT) for the final 30 mins which by definition should be a TSS of around 50 for those 30 mins.
If true then a significant difference between hrTSS and power TSS could be a really handy insight / indicator.
I’m experimenting with power based work on the turbo trainer and I am looking to see where my power at Hr AeT lies relative to FTP and the traditional % of FTP zones that are in the literature.
