Iñigo San Millán training model

[Captain_Doughnutman]

Thought I’d post my n=1 recordings.
Perhaps the best one I have is from a cardiac stress test I did on the trainer.
Visually it tells me one thing, numerically another; so…I can only guess at the efficacy.

Inflection point @ 115bpm with DFA/alpha 1 @ 1.18…

…however, DFA/alpha 1 remains steady (at above value) until ~132bpm when it drops 25% to 0.88 (now showing RR graph):

So, do I believe AeT is at the visual inflection point (115HR), or the “mathematical” inflection point (132HR)?

My theory is that 115 is perhaps more my FatMax and 132 my AeT (which is also consistent with my MAF). Insights?

Also, a post on a different HRV thread which might interest you:

Anyone using HRV? (Heart Rate Variability)

thanks! My take is the following: many HRV features are simply statistical ways to look at the same thing (variability between heart beats, or changes in heart rhythm), hence they tend to be highly correlated. Historically, a few features had been used more than others, for different reasons: SDNN: this was used in the context of 24 hours measurements, so that we would get an understanding of cardiac variability changes throughout the day, as a response to circadian rhythm and acute stresso…
