Training Zones and Blood Pressure Meds
Say my max heart rate was 175. Then I am put on blood pressure pills - beta blockers - that are known to suppress heart rate. Now, my maximum heart rate (same course) is 150.
In setting training zones (e.g., if I want to ride at 70-80% of my max), do I now use 175 or 150 as the maximum on which to base the percentage zones? On one hand, if my body is still pretty much the same except that my heart rate is artificially suppressed, it makes sense to continue using 175. On the other hand, if the max at which my cardiovascular system can be driven is 150, then perhaps cardiovascular work needs to be geared to that level.
Has anyone ever seen authoritative commentary on which is the right view?
