HRM Questions

When you first started training with a HRM:

Did you learn you'd been training at a much higher rate than you thought, and higher than you should be?

When you slowed down to keep your appropriate HR, did you feel you'd slowed to a shuffle? I am running the lowest training paces of my entire life trying to keep my rate down (usually 130-140 on easy runs, as advised by my coach, whom I trust very much.)

Did your pace on normal or easy training runs change? Faster or slower?

Eventually did you become able to maintain a higher pace at a lower HR?

Does your HRM ever show outrageous momentary or max rates that make you wonder WTH?? I've wondered if: I threw some double or triple beats w/o feeling them; or if my ID dog-tag whapping against the chest sensor was being interpreted as beats (I've been hanging it down my back since then); or if there was some other kind of interference when you weren't near any power lines? Or if in fact your HR was over 200 at some point?

I haven't really seen 1140; I messed with the picture in PhotoShop to be cute :-) I have seen over 200. If I saw it when it was happening (as opposed to a recorded max at the end), a manual pulse check yielded a non-lethal rate like 150 or 160. And it didn't seem to change my average rate (which I do manage to keep within the parameters even though my max often goes over.) That's why I'm wondering about the dog-tag whapping, or some other kind of artifact. Like when I've tried to use a pedometer, just the bouncing as I move gets counted as steps.

LOL, I noticed the photoshopping first. :)

Ellie, when I first started training with a HRM, I also found I was training higher than I thought I should be.

But, really, there is science behind the base training at a low HR. What you'll find, is that after a couple weeks at this, your pace will increase at the same heart rate. Coach certainly knows best!

The ID tag shouldn't bother it (I wear one as well). Did you make sure to wet the electrodes? Maybe you don't have a good "connection".

I occasionally have a heart rate murmur when dehydrated that will cause my hr to jump to 210+ due to a skipped beat.

Holy cow, if your max HR is 1140 :)...u got so much HR zones to work on :)

My HRM tends to mess up when I do interval runs. It is more likely to mess up during winter time as well.

Yes on my slow one when my HR is low, it is very slow. Back in winter, i was training with an HR of mid 130s. That's super slow. I think i am going like 12 min/mile. This is compare to 160 when I think i run about a 8 min/mile.

As far as pace changes, I haven't taken enough data to find out. Effort wise, i believe i am running faster with a lower HR.

funny girl! HRM training is tuff for the reason...can't seem to keep it low enough. It takes time...major time, to get to a place where you can get faster and keep it down. I only wear it on long runs since everything is hills or interval & I don't monitor that (maybe I should). Anything too scientific and I can't hang. All else good??

I used to use my HRM all the time. I got kind of burned out. I tend to get too serious about things. Triathlon is easy for me to go overkill but it's supposed to be release. I stopped wearing the HRM, and my workouts were more fun. Now, I pay attention to my breathing rate and perceived effort to monitor how intensely I should be going. It works well for me.

I use my HRM more for curiousity to see if I am working hard enough and ya know most times I

I know lots of folks who have been forced to slow down and stay in a low HR zone. I don't know the science behind it but apparently it works.
Make sure your max HR is correct or it throws the rest of the math out the window.
