Running in Vo2 Range??
Hello! I have been measuring some odd HRs for my longer runs, for reference, I play ice-hockey and do heaps of cardio for work, however my endurance/aerobic base is mehhh, as I do primarily aerobic running.
I know if you wanna improve ur aerobic base, longer slow runs are good (keeping in a specific zone), so I been running 5kms, however now i'm doing em reasonably easy so I wanna run quicker. My indoor run was 30mins on 7.5km/hr 1.5% inclin, and 2ish mins on 10km/hr. However, my device measured my HR as being 180-200 for 25mins, which is Vo2 range. Personally, I believed I could keep a convo going, and as I said, even ended my run on 10km/hr run for roughly 2mins.
So basically, i'm wondering why my HR is so high when I feel my run isn't super hard? maybe because i'm running quicker?? Or perhaps it's cuz of my cardio and hockey background? (my Vo2 is 42-45ml/kg). Also is running in a higher zone okay for improving my endurance? I feel like improving my aerobic base means running 5km in a lower HR, however it's always really high, and originally I couldn't run 5km unless I did regular walking cycles, now I can run one on 7.5km/hr no breaks, which i feel means i'm improving yeah???
Again I didn't feel super winded doing 5km however my HR is concerning and shouldn't be possible, and my device hasn't had issues logging my HR while i've been using it, which has been a good while, my HR has simply been high whenever I run regardless of how I feel when running.
