The other day I had to workout where the intervals prescribed 200% of ftp, then z5, then all out.
I found that for the second and third opening sprints, my heart had trouble going from a recovery mode to the demands of the sprint efforts. This is just a thing that my body does (observed by a cardiologist), I can’t fix it. I’m 31 now and I started to notice it when I started structured training 3 years ago.
But as far as cycling goes, it means when I suddenly go hard, I have to lay off, wait for the heart, and then make the best of the remaining Z5 time. The all-out 30 seconds at the end goes fine, tho my power is below the suggested target watts. It’s just that from-rest to sprint stuff is sometimes very hard for me to achieve. It’s gotta be a perfect day to snap from a recovery interval.
Any thoughts on this?
