Not something I’ve heard, however there are more Seiler podcasts on my playlist saved for a future listen.
The few podcasts I’ve heard Seiler talk, if memory serves correct that he was pretty explicit “sweet spot = zone 2” and should be avoided. At least on Fast Talk episode 54 where he defined zones.
Are the 16 min intervals you are referring to from the Seiler/Joranson/Olesen/Hetlelid 2013 “Adaptations to aerobic interval training…” study involving 37 recreational cyclists?
Because Seiler isn’t a coach, my question for @Mikael_Eriksson is to ask Dr Seiler the following questions:
- which cycling coaches have adopted polarized training?
- do those coaches only use polarized training, or do they only apply it to certain phases of the training year?
- do those coaches use sweet spot and/or tempo training with their athletes, and if yes, during what phase of the training year?
- I’d also like to hear what Dr Seiler thinks of Sebastian Weber’s remark (paraphrasing here, from EP#169) about how if sweet spot training works, and polarized works, they both have something valuable to offer and which to use depends on the specifics of the athlete at a particular point in time (its similar to Joe Friel’s comment on Fast Talk episode 68 podcast)
