Maximum HR decrease?

[rudi-h]

I've been training with a HR monitor for about a year now. When I started I could, with effort, get my HR up to around 192bpm and actually measured 195bpm once or twice.

 

Now days I have to almost pass out to get to 187bpm.

 

I was under impression that maximum HR only decreases by a couple of bpm per year.

 

So do I need to get my HRM checked or is it something to do with getting fitter.

 

It might be a result of over-training. If you take 2 or 3 days off completely and you do a max HR test on a treadmill for example, you should easily get back to 190 something. HR goes higher with running than with cycling IMO, but if you ride hard enough its possible on a bike too
