I’m not comparing INSCYD AT (251w) vs TR FTP (276W). I’m comparing INSCYD PVO2max (261W) vs TR FTP - and an implied TR PVO2max of ~330W (120% of FTP).
The OP said they can do workouts like Kaiser in TR (3 min intervals at 330W), which would not be possible if PVO2max was actually 261W.
With VLaMax = 0.1 and Lactacte_Rest = 2.0 your highest possible measured lactate value can be 3.2… I would go back to them…
@tofel Were you using the same bike? power meter as at home? or their bike?
I’m currently in the middle of the power based protocol. I say “in the middle” because my 15 sec sprint is irregular (likely due to trying to do it on a wheel on trainer…will do it outside once the weather clears). It was .28 but we’re suspicious of that value.
My other values in the report did not surprise me in the least, and have been very helpful in some cases (particularly fueling).
Because of the odd data point, the lab that did my test is going to show Sebastian my numbers on a support call in a few days. Wonder if you could get your lab to do the same.
If it’s helpful, I’m happy to share mine but don’t want to do it until we’re confident the VLamax is valid. In other news, ramp test, baseline progression, 20 min, and 8 min all overestimate my theshold (big surprise, not). I’m now using INSCYD’s anaerobic threshold range (yep RANGE, guys!) to drive my training moving forward.
Not same bike, but the same smart trainer I am using at home.
On my last ramp I did
1min 368W
5min 336W
Using the ramp test, TR sees my FTP at 276W. My INSCYD Anaerobic Threshold (zone) is centered at 251W (it ranges from 233W to 268W). So if TR-FTP=Upper limit of INSCYD AT zone, then they are not too far from each other. Especially, if the ramp over-estimates FTP.
INSCYD AT and TR FTP do add up.
INSCYD PVO2max does not seem consistent with what you are actually able to do.
Exactly, @DaveWh This is what I do not understand
In the INSCYD test protocol, did you do a 4 or 5 min test? What was the resulting power?
I don’t know how to interpret what’s in the chart. What was your power in the 3 min and 5 min intervals?
@tofel @DaveWh I agree with Dave as well. If you would’ve gotten the same AT values from INSCYD as a TR ramp test, I would’ve been suspicious. FTP simply isn’t lactate threshold. The degree to which it differs is highly individual.
Ramp test FTP = 284W.
INSCYD AT centers on 277W.
At first I think “oh that’s not that different”. But my medio range target is 234W. Your Medio target is 20w lower even though we have similar ramp test results.
What I’m trying to say is that this part seems correct. I would question the data @DaveWh is talking about
Yes, the first two rows are the average power and corresponding time of the run.
They measured the development of lactate at four different runs at different respectively same Watt levels. It is less about achievement than lactate values over time for different power levels.
This is 100% the case for me
The Watt levels were chosen beforehand. You are put in ERG mode throughout the run and required keep your cadence consistent during the run. Cadence was 85rpm, except for the “All-out” run, I chose 100rpm there (maybe this skewed things).
So how do they estimate VO2max? Did you do any effort in the INSCYD protocol that felt like a Kaiser interval?
Good question. My assumption was that VO2max was tested via a mask…since lactate values are measured by „real“ blood samples.
Outside of the discussion of mathematical impossibilities etc, this page from Joe Friel has some good suggestions for sessions which could improve your VLaMax. Go find a small local hill…
