I regularly run on a variety of treadmills (all Life Fitness) at the gym. I use my Polar HR watch and chest strap and that works fine on the LF machines. However I consistently see a jump of around 30bpm after I have been running for anything between 1 and 3 miles.
I am currently following Hadd training which for me means doing 4-6 miles at 125 HR and my wrist monitor and LF console both agree on my HR and then with a few seconds the LF console jumps from 125 to around 166 and generally stays consistent so that whereas my HR might go to 128 (both on what I believe it is and what the wrist monitor is telling me) whereas the console will go to 168. That remains high on the console until I finish the run.
I can even take off the chest strap or hold the hand rail pulse sensors and it will still not lose the 168 reading.
Recently I was doing a faster session and it showed a consistent 178 HR on the console which is pretty impossible for me for anything other than a 100% effort for 10 yards. My MHR is 168.
Does anybody have a similar experience?
