Always so entertaining to see such confusion over the FTP concept.
I know someone who suffers from a loss of metabolic control after 33 minutes at 100% FTP so the poor chap has to ride a 40k TT at well below FTP.
People should stop confusing what FTP is with how to test and estimate FTP.
FTP is power at MLSS which can be maintained for anything from 30 to 80 minutes before loss of metabolic control, but on average most people can maintain it for approximately 60 minutes or approximately for 40k. ( "on average about as long as it takes someone to complete a ~40 km TT, but with some variability between individuals. Based on the WKO4 model? 59 +/- 13 min").
Well, that's what FTP was a few weeks ago. Life was far simpler when FTP was the power you could maintain in a semi quasi state for approximately 60 minutes or a 40k TT but that was just so year 2000 thinking. Things have moved on and Dr Andrew Coggan PhD who invented FTP has said, " ..the notion of a power threshold power is really the same sort of mental convenience as the notion of a lactate threshold. Regardless, anybody in the field worth their salts realizes that the notions of "thresholds" are really just mental conveniences, i.e., that the underlying physiology isn't quite that simple, ... """ and Alex Simmons who really does understand FTP can explain why some people can only maintain their 60 minute power for less than 40 minutes and are unable to ride a 40k TT at 100% FTP.
Obviously some people have always said FTP is a load of complete bollocks because the simple fact is the longer the duration the lower the power, but they are just confused, don't understand the concept, or trolls.
