@jem_arnold It’s something like this: https://t.co/xGjYXGjfnj – so, none of the above :-)

@CoachSusigan For athletes, I think that steps longer than 3 minutes only bring disadvantages ...

@jem_arnold You should try a mixed model for repeated measures (MMRM). That includes modeling with a variable number of individual results ... 🧐

[Ergonizer Software e.K. @ergonizer]

@jem_arnold Yes, most sprinters hyperventilate heavily after their race. And that's not just to breathe out CO2 ...

@felipe_mattioni @uni_tue 👍👍

@Alan_Couzens Interestingly, the original conclusion sounds different: "Both LOW and MIX training programs improved performance and V O2peak by the same magnitude, whereas LOW attenuated the blood lactate response to a given exercise intensity more so than MIX". No influence on performance!?

@Alan_Couzens Now it works, sorry!

@jem_arnold @nntaleb @Alan_Couzens @waydiscipline The picture shows the hyperbolic increase pattern that I mentioned above. Since that is always the same, it is irrelevant at which moment you take your samples - you only have adjust the level …

[Ergonizer Software e.K. @ergonizer]

@jem_arnold @nntaleb @Alan_Couzens @waydiscipline Here's to consider that lactate also accumulates to some extent. Therefore, increasing stage duration results in increasing fuzziness. You measure something that did not happen at the respective step. That also applies to the LT(1) …

@jem_arnold @Toptimum_Perfor @JonasZakaitis @thenwerun And lastly: Unfortunately, 125W was left out here. This significantly worsens the possibilities for interpretation.

[Ergonizer Software e.K. @ergonizer]

@jem_arnold @Toptimum_Perfor @JonasZakaitis @thenwerun Another thought: reliability and exactness also counts. Not given with the publication cited. But my feeling is that both gets worse with a longer step duration (less values means less averaging).

[Ergonizer Software e.K. @ergonizer]

@jem_arnold @Toptimum_Perfor @JonasZakaitis @thenwerun I think this is good indication of my view: one could calculate identical references from each of the curves shown. The informational content is similar in each curve (little bit better at 3min). What is sometimes called LT2 is not a physiological but a computational phenomenon.

[Ergonizer Software e.K. @ergonizer]

@Toptimum_Perfor @JonasZakaitis Could it also be that he is not reaching his 2:34 because he's going on too fast in his race attempts (due to his reduced exertion sensation)? Anyway, I do know too less about the case. That's the point.

[Ergonizer Software e.K. @ergonizer]

@Toptimum_Perfor @JonasZakaitis @thenwerun I do not think (or say) that step duration does not affect lactate concentration. I meant that a changed duration does not affect reliability of any anchor points: A threshold is relatively as high with 2 minute steps as with 10 minute steps. Just at a different level.

@spinmonk @JohanTanman @Alan_Couzens @Marinak12781887 Oups. That is important to know! I'll send an link to you privately ... sorry for the inconveniences.
