How should I define my HR training zones according to this result? Does the V1 Value should be the top of my Z2 (Joel Friel 5 Zones)? Cause it doesnt match with what is calculated for a LT of 178bpm…
But I still not understanding it. As I mentioned, if I use any of the HR Zones calculation methods (Joe Friel, MyProCoach, etc.) my Zone 2 is way higher than the value above…
The body doesn’t know or understand zones. There is, in my opinion, far too much emphasis placed on what our ‘zones’ are.
You’ll know yourself what your zones are.
To give you an idea … I am still not recovered from COVID that I got last July. Ask me today to go out and ride 315 watts for an hour and I guarantee I can do it (not that that is anything to write home about, but hear me out). That would put my Z2 to about 175w to 235w. It’s nowhere near that however. I estimate at the minute that my upper Z2 (aerobic threshold) is 160-170 watts.
So I have my FTP in at 280 but that’s really just to track TSS. My endurance spins at the minute are done at 150 -160 watts (down from 210w a year ago).
Forget about your ‘zones’ on paper and ride to what they actually are. You’ll know by your breathing where you’re at.
Summary - If you think you might be going too hard on an endurance ride then you’re going too hard ;-). It doesn’t matter a jot what Coggan’s or Friel’s zones say you should be doing. Ride to feel on those aerobic spins. You’ll know yourself without ever looking at the watts or HR
An ergospirometry test is a ramp test to exhaustion with the purpose of eliciting VO2max. AT/FTP is very roughly about 75 % of max power.
Unless this was another protocol?
