Is it possible to add the Astrand Ryhming test to the Vo2Max approximation? Just find a 6-minute segment of a ride with a constant load and heart rate. You can also calculate Vo2 for different powers and find the power for which Vo2 / power (or power / Vo2) is best or worst. But it should be a linear relationship, although my intuition tells me that it changes on the thresholds (LT1 LT2). You can follow the calculated Vo2 calculated for your lactate threshold heart rate and see if it rises or lowers with training.
I think that may already be on David’s to do list: https://forum.intervals.icu/t/pvo2max-in-relation-to-pftp/1042/27
Seems was originally planned to be implemented with the MAP chart though. Did implementing VO2max run into obstacles @david?
Having read this paper on the Astrand Rhyming method, it is quite different to the ones covered in that other thread, being very submaximal. I imagine it could be hard to automatically tease appropriate efforts out of users’ data.
Vo2max estimation got bumped down the list unfortunately. This separation from Strava stuff has taken a lot of time. There are a number of ongoing issues I need to sort out (duplicates, some signup and login issues, Stripe support) before I can get on to new features again.
The MAP chart needs nice data or it just doesn’t work out (for most athletes). So I need a different way to get VO2max and will look at the paper.
This thread has a lot of info:
