First time poster here. I’ve been enjoying TR for a few months now and on completing by third ramp test this week and taking a closer look at the numbers I had a realisation:
- As your FTP goes up, the starting power and the size of each step also goes up.
- This means you arrive at the peak power of your previous test sooner and with fresher legs
- Consequently, you can exceed your previous power, even if your fitness has not improved
- If FTP=75% of highest 1-minute power then this will result in a higher FTP being awarded
- Return to step 1 and repeat
Isn’t there a positive feedback loop going on here? Even at a constant level of fitness, each time you take the test it will get a little easier so you will get a higher FTP so it will get a little easier the next time and so on?
For reference, take a look at the last two ramp tests:
(1) 11th Dec, 339 FTP awarded (318 going in) https://www.trainerroad.com/career/rupertb/rides/68184105-ramp-test
(2) 4th Feb, 345 FTP awarded (339 going in) https://www.trainerroad.com/career/rupertb/rides/72442429-ramp-test
[Ignore the final minute in (1): I got out the saddle (I know I shouldn’t have) but this didn’t affect the result as average power for the final minute was less than for the preceding minute. FTP awarded was bang on 75% of the penultimate minute at 452*75%=339]
In ramp test (1) I start at 146W and each step the power goes up by 19-20W.
In ramp test (2) I start at 156W and each step the power goes up by 20-21W
Therefore in (2) by 1-min power peaked at 20:00 whereas in (1) it peaked at 21:00. In other words in test (1) I had to fight for longer in order to reach a lower power than in (2).
Now I’m thinking that the small FTP bump of 6W from my last test may be illegitimate. Let me know your thoughts. Would love to hear @chad and @Nate_Pearson have to say, too (huge fan of the podcast, guys)
EDIT: sorry if this has already been covered before - let me know and I’ll remove the post
