TL;DR, CP and FTP are describing the same thing. That is, the phase transition between the heavy and severe exercise domains.

I think where FTP became defined as a 60 minute max effort TT is from confusion of Dr. Coggan's wording in his paper. He suggests an _approximate_ 40 kilometer TT which should last approximately 50-70 minutes.

It's practical to simplify it to 60 minutes as it's a practical test. But FTP is not defined in terms of time, but in effort.

Dr. Coggan was aware of the critical power model and also mentions that in the paper:

"Conceptually, critical power is a power that can be sustained “for a very long time without fatiguing”, and is “an inherent characteristic of the aerobic energy supply system”. Experimentally, an individual’s critical power has been found to be closely related to (although again somewhat higher than) their power at LT as determined via laboratory measurements.

Continued thread

"... functional threshold power is therefore to simply measure their average power during a ~40 km (50-70 min) TT. This highly pragmatic approach is justified by laboratory research showing that the power a cyclist can generate for 60 min correlates very highly with, but is slightly greater than, their power at LT (defined as a 1 mmol/L increase in blood lactate over exercise baseline)."

IE, FTP describes the same phase transition as CP.

I was under the impression that the difference between critical power (CP) and functional threshold power (FTP) is:

CP: power that represents the phase transition between heavy and severe intensity domains. Roughly LT2/VT2/MLSS.

FTP: the maximal power you can sustain for 60 minutes. Estimated as 95% of a max-effort 20 minute TT.

Dr. Andrew Coggan defined FTP in his 2003 paper "Training and racing using a power meter: an introduction". How did he define it?

A nice 10km course around the ‘Idroscalo’ in Milan with many participants and very warm. ☀️

I had covered my watch with tape and was planning to run around 6’45/km by feeling, but to my surprise I suddenly saw the 50’ pacers in front of me. 🙈

My clocked time was 50’48. I don’t know the official time yet. No medal this time, but a nice shirt again. ☺️

Nice run! 🏃‍♂️

Everyone I meet on my runs gets a smile and a friendly "hello" from me. It's actually quite selfish. It costs me nothing, but every smile I get back gives me strength. Especially this elderly lady who is walking regularly along the Moselle. She seems very bitter. She always gets a special friendly smile and, on Saturdays, a "have a nice weekend." When she smiles and says hello back, it gives me superpowers. 😀🏃🏞
