Conversation starter… Can anyone shed some light how quickly could HIE decline relative to the other parameters?
I am seeing interesting situation. I was in a several month base building block with pretty good hours almost every day. I got to nearly five stars TL and my Fitness signature got up to something like 1300W PP 28 Kj HIE and 417W TP. Mind you, not so much above 4 wkg
Anyway, I live far above polar circle and it got just too hard to maintain longer hours. I got back to shorter rides, more sweet spot and Zwift racing, expecting moderate fitness progress. Need to survive until end of April.
But. I noticed my above threshold work capacity is going down. I can hit high TP no problem, but just a month ago my HIE was much higher, I estimate it should have dropped by almost 10 Kj. It just got easier for the opponents to wear me out in the rolling terrain and I feel like I am on my way to being one trick pony again.
Does it make sense? Any ideas what could be going on from physiological point of view? I will sprinkle my schedule with above TP work with incomplete MPA recovery and hope it will help
