Hey guys, can I manually enter my HIE? Xert estimates my HIE@37,1 KJ. If you are not a 400m runner or a cycling spring classics victory contender or something like that, that value is completely unrealistic. From monitoring my FRC in anaerobic intervalls (W’ balance app for Garmin) my HIE should be rather in the 16-20KJ ballpark which already is quite a fair value. WKO5 has determined a cycling FRC of 15,6 KJ.
The result: all SMART exercises with target MPA that are above 3,5 stars are completely unsustainable. Hardest I can do is Micros with Target MPA 4.0 (I do it as a substitute for 30/30s), this is only 3.5 stars. This workouts includes 3 60 second intervalls that ask me to do 405 Watt (FTP is 260 Watt). I can complete the 60s, but then I have to stop due to suffocation (although legs could sustain further punishment), it feels like I am dying, I need a ~15s rest before I can do the recovery intervall (30s). Rest of the workout is easy-peasy lemon squeezy (sure it is hard, but I do not even have to start to “negotiate” if you know what I mean).
Is my assumption correct that if my Xert-determined HIE was lower, the targeted MPA would stay the same, the suggested duration would stay the same, but the suggested power would drop? Because if I understood the “model” behind Xert right, lower HIE with same Peak Power (which Xert determined quite accurately) should result in a faster MPA-drop in efforts above FTP.
Supra-Threshold using Target MPA - 4.0, four stars difficulty. It suggests me to do 6 minutes of 330 Watt. My Power@VO2Max is 325 Watt. I cannot do that. Plain impossible, no matter how restend and motivated I aim. I can do 5x3min@315 Watt.
I am aware that non-pros are not supposed to complete a 5 star workout. But I could do “harder” workouts if my HIE was determined correctly.
