I did my 20 min FTP test a few weeks ago. This isn’t the first time I’ve done this test, however, I either tested very poorly (which I don’t think was the case b/c I was dry heaving at the end) or my HR as I age is getting substantially slower.
I naturally have a very low HR. In the past 5 years or so I’ve been training endurance rides at 120-130 bpm and Tempo at 130-140 bpm. Currently, the power zones that are set for me have me in an endurance zone of about 117-125. Even during the muscle tensioner portions of the rides, I’m barely breaking 120 bpm. My average HR over a long endurance ride isn’t coming close to 120 bpm but I’m hitting my power targets.
While I do feel my peripheral system working, I’m wondering if my cardiovascular system is being stressed enough with the current power targets?
Did I just test very poorly or is my ticker slowing down even more?
