True, and no harshness taken, it’s always good to revisit and refresh one’s strategy. However, my current training (if that’s what it can be called) is based on the following considerations:
- Being heavily de/untrained for the better part of the year, I’m back to making those “noob gains”. My requirement for a high degree of specificity isn’t a requirement at all.
- In lieu of specific/personalised laboratory testing, I’m relying on the information of those who have years of testing knowledge and experience.
- My “data” isn’t specific, but then again, I don’t believe my personal physiology differs significantly from the larger pool.
Regarding testing, all of it has been conducted in the pain cave.
I know my HRmax and according to Friel, AeT occurs at ~70% HRmax.
(He also claims AeT+30bpm ~LT.)
For the record, I rely more on HRR calculations than HRmax.
It’s been assumed that MAF is the upper end of Z2 (power)
I have conducted several ACE protocol talk tests to establish VT1.
I have conducted several HRV protocol tests to establish VT1.
I rely on published conclusions from several lab testing experiments to establish a FatMax zone.
To continue the Couzens quotes, “…if I was dealing with beginners or low volume athletes [me], where the difference in output between ‘recovery’ and ‘base’ wasn’t all that substantial, a 3 zone model might suffice…” My understanding is that in a 3 zone model, Zone 1 correlates to 55-85% HRmax/50-70%HRR/55-75% FTP; my training range falls well within Zone 1. Maybe when I turn pro I’ll seek out some of those precise 7 zone marginal gains.
Even the lauded FTP is an estimated anchor (of which I have also estimated using a proxy protocol), so I’m not overly concerned with true exactness, especially, and I think rightly so, at the lower/est intensities. Yup, all ball park, but at this point, the possible differences between lab procured thresholds vs DIY values isn’t causing any great degree of damage (nor would being ‘bang on’ create significantly greater gains).
As Couzens also says, “the number of training zones need to be sufficiently precise to cover the major training objectives of the event.” The training objective of my “event” requires but a single training zone, which I believe is sufficiently fuzzy enough.
