Ok, forgive me for starting yet another thread on FaCT, but Juerg's FaCT Clear and Simple thread unsurprisingly was neither clear nor simple and has degenerated into a PhD thesis on Oxyhemoglobin Dissociation Curve and it's inverse relationship to the UCP3 and UCP2 messenger ribonucleic acid.
Ok, let's see if I've got this as far as the methodology is concerned:
You do the high tech test with lots of laptops, projectors and other highly impressive technical stuff that Rob likes so much and then he will put all the numbers produced in a big pot and pull out one which will give you a heart rate to train at...it seems to normally be LBP-20.
Why -20?
Why not train at LBP or LBP-5 or LBP+8?
Then, in a few weeks/months you go back, pay Rob more cash and he does another super impressive high tech test, probably with even more graphs and numbers, to see....errrr... if your biomarkers show improvement?
Basically does this mean that for the same watts your LBP has gone up a few bpm?
Then what?
You carry on training at LBP-20, which will be a slightly higher HR but still very low?
So, do you keep having to go back to Rob and get tested every few weeks/months to see if you can change your training range? If I was being cynical, I'd say that this was a nice little arrangement for the tester, since it's not a one-off thing. Punters keep having to go back.
Putting my cynicism aside for a moment, how does this help racing form which is all about threshold and above performance i.e.top end stuff?
