I have been running relatively regularly in the last several months. I noticed that my pulse now is quite low, it used to be about 60 and now it is around 52 or so.
This could be a result of two things, an adaptation to running, or insufficient dose of thyroid hormone that I am taking to compensate for absense of 2/3 of my thyroid.
I would like to know if, in your opinion, regular jogging over the period of about 8 months could lead to change in RHR from 60 to 52.
