How do people approximately calculate their LT1 and LT 2 without a blood test?

yep - definitely do longer . steps to allow levels to stabilise. Marco suggests 6-8 min steps and every time I’ve seen people here use shorter steps they also seem to get strange numbers. Have a look at his suggested protocol in this post. [image] HRV Logger FAQ The Heart Rate Variabili…

For all of these tests, very much need longer times at each step. Throw away anything you have read or done with three minute lactate (or other) tests with short times at each power level. For LT1, this power level is well within the ability to ride for a long time. Set up a workout with 8-10 min s…

I recommend you guys do this test by HR rather than power. You can start with an estimate. San Milan suggest the talk test. Seiler recommends 65% of HRmax. Warm-up, get your HR in that range and see where DFA a1 is. Go 5 beats higher or lower depending on the reading. Once you find your DFA a1 he…

[image] GoLongThenGoHome: I’m in a base block at moment. I’m 4 weeks in and will keep it in base till mid March. I see LT1 as a cap but I do tend to ride as close to it as I can. I have regular 1.5 hour up to 2.5 hour loops plus 3.5 to 4.5 hour loops. Currently I’m at average 8.5 hours of riding…

Hello, in my DFA Alpha 1 records i can see some extrasystoles, especially when my puls / power changes (goes up or down). In this example i did a 3 minute All-Out effort. The green line is the power output, and the black dots are the RR-Intervals (millisecounds between heart beats). Still have be…

Thought I should point out that alpha 1 isn’t just for finding lt1 threshold but can also be useful to track fatigue https://physoc.onlinelibrary.wiley.com/doi/full/10.14814/phy2.14956 Another reason why I’d love tr to be able to do the recording and calculations in the app to help train the model…

Doesn’t TR need to be recording RR interval first? I thought that they had updated it to record it, but I didn’t see it when looking through the settings the other day. My .fit files exported to garmin don’t have it, so Kubios cannot do any analysis on the TR files.

[image] AJS914: You can start with an estimate. San Milan suggest the talk test. Seiler recommends 65% of HRmax. these are too vague or too low. Better to do the ramp test. [image] AJS914: I’ve found that actual power at DFA a1 will fluctuate with freshness. This is true and very key,…

[image] Bioteknik: Doesn’t TR need to be recording RR interval first? They don’t. This is not really a simple ask as getting good data isn’t simple. -have to use ble over ant+ (so need some way to tell users which option they should pick which is more a UX problem) -have to identify which s…
