[image] FTP, VO2max and VLaMax: what triathletes need to know with Sebastian Weber |... Sebastian Weber is a sports scientist and highly successful coach, in both professional sports (having worked with athletes like Peter Sagan, Tony Martin, and André Greipek) and with age-group enduran…

[image] roflsocks: Given any two values, you can calculate the 3rd. (1 + 1 / Vlamax / Vc) * Vo2max * Pc = FTP This uses two constants, one is a multipler for vlamax, and one for overall power output. Vc is the Vlamax constant: approx 7.43 Pc is the power constant: approx 3.45 @roflsocks : …

[image] tofel: This is a plot of your function FTP Looks good. I think showing some isoquants for FTP on a 2D chart would even be better for readability…

Yes, if you know two the third can be calculated. Not sure what the formula is, I know it can be done in the INSCYD software at least. But @abalakov when you say FTP can be tested - a classic FTP-test has zero value in this case. And even a lactate test isn’t really that accurate. Same goes for est…

This is a great observation. I don’t yet have a massive data base of tests to draw from, but from what I’ve seen so far, a fractional utilisation of 76-80% is not at all unusual (the lowest I’ve seen is in the 73s) and neither is 86-88%. 84% may well be pretty good as an average but the variance i…

There is a regression model in there for sure, but it’s as far as I’m aware not fundamentally built upon just a regression model, but actually on an equation system of biochemistry, because we know exactly how much ATP can be produced anaerobically with glycolysis and aerobically with oxygen etc. Ex…

@tofel : Wow! This is perfect. It really nicely shows sensitivity and the axis you need to work on to get to the next step…from a marginal gain perspective.

@tofel : just a remark: if you want to push it even further, you could invert the y-axis so that improvements go from right to left and bottom to top. And not everybody will start at 50Vo2max. Don‘t get me wrong, there is no need for any changes, just if you are striving for perfection…

I’m a triathlete. So if I want to maximize my performance on the bike I should focus on getting my VO2max as high as possible, and VLAmax as low as possible. Without knowing my actual VO2max and VLAmax, I should still be able to monitor progress by performing the following test every 6 to 8 weeks : …

Let’s say as a die hard TrainerRoad user I want to try to lower my VLaMax. How would I even effectively do that following TR plans? Just do Sweet Spot Base repeatedly? I mean even Sustained Power Build appears to be too heavy on intensity and too light on Sweet Spot.
