Anaerobic Training Effect - how does it work?

I've been a little confused. Since firmware 17.xx or so, I get no longer  an anaerobic TE (AnTE) of more than 2.7-2.8.

Example: Yesterday my DSW was a sprint, 7 x pace 3.20 for 10 seconds each. Expected AnTE - 3.0. So far - so good. I went a bit faster - @3.07 - average. Should work?
To monitor my AnTE I created a separate data field where I can see what  AnTE I have after each interval.
I got the following measurements -
The total after each interval - 1.2, 2.3, 2.5, 2.6, 2.7, 2.8, 2.7.
And yes, as you can see, for the last interval I got negative values ​​- the sixth was 2.8 and the seventh was -0.1, so that in the end I had the total of AnTE - 2.7.


Some time before that I wanted to reach 3.0 on every price and on DSW [email protected] I did 11x and what did I achieve? AnTE: 2.8, nothing more. And my legs were dead the next day.

Same pattern - at the beginning - +1.2, +1.1, so huge increase, then, +0.2, on 3rd repetition +0.1 and... nothing more.

Can someone explain to me what I'm doing wrong?

PS I use chest stripe and Stryd every time I do ints.

    I did that mistake in July. My interval session was 800m, 700m, 600m, 500m, 400m, 300m, 200m, 100m. I ran at the speed I could maintain for each distance, so the 100m was pretty much full sprint. I have fast twitch muscles, so that is too fast for my age (53). The result was strained hip adductors, and I still can't run properly after that mistake. I also found out that the cadence got too high for my Garmin chest strap. It reported zero cadence at my top speed. It was probably around 250+ in reality. Stay safe with those sprints!

    That's what Garmin tells me (autodetect).

    Good. Garmin has improved their algorithm (in the past year maybe) and now it seems to be reliable enough.

    Today i done 8x20sec@3:05 min/km, and got a aTE 3.2 and anTE 3.1.

    Coincidentally I did a DSW anaerobic workout 7x40s and I got the same TEs as you. I ran my maximal steady pace as usual and I ended up right at the upper limit of the target pace zone.
