Heart rate training effect with pacemaker
I haven't been able to form a useful Google search for this question, so I'm hoping someone here will have an answer.
Most athletes understand the concept of the "training effect" -- challenge the body (including the heart) to perform at a higher-than-comfortable level over a number of intervals, to accustom/train/strengthen it so the higher level becomes the "new normal"... and repeat.
So I'm wondering, since the pacemaker controls the heart rate more or less independently of the body's requirements, does gradually increasing one's efforts *with* a pacemaker still lead to the same improvements as it would without one?
Before my pacemaker, I was walking on a treadmill 5 miles a day, 5 days a week, at about 3.5 mph/17 minutes/mile and 3.0% grade. It's been about 10 months since implantation, and I'm back up to about 3 mph/20 minutes/mile and 3.0% incline.
The HR monitor on the treadmill isn't very accurate, but it does seem to be consistent from day to day. If my current program results in a heart rate around 95BPM and I push the pace up to 3.5mph over several weeks, such that my heart rate initially goes above 95, can I expect that eventually the training effect will bring it back down to around 95 at the new pace?
Thanks for any insight on this!
