In part 1 of this video Why the Anaerobic threshold (MLSS) of INSCYD does not equal your FTP – pt. 1, we talked about the difference between MLSS and FTP or Critical Power. In this video we talk about why a 20 minute or 60 minute FTP test does not give you the right information about your anaerobic threshold (MLSS), even when subtracting 5% or any other percentage.
Subtracting a percentage from an FTP all out test may work on average, but it reminds us of a statistician who put his head in an oven and his feet in a freezer, and jokes: “On average, I feel fine.”
In the video, Sebastian Weber shows some examples that clarify why doing an FTP test does not give you reliable information, even when subtracting 5% of the average power. One of those reasons is that the percentage you should subtract differs per person AND it differs between two tests of one and the same athlete.
Moreover, the anaerobic threshold itself is maybe not that interesting.
What is really interesting: How fast you accumulate lactate above this threshold and how fast you recover from a lactate accumulation
