>General Running>Polar Heart Monitor
Because of my age and weight I am confining my running to a treadmill whereI can monitor, speed, distance, incline etc and build gradually.
Because I dislike holding onto the pulse monitor hand things I purchased a Polar T31 uncoded belt which I am told is the correct one for my treadmill.
When I am starting off the pulse is around 78-80 which is correct for my age etc. Then as I start to run the rate actually drops to around 60 which is weird. If I take the strap off and go back to the hand held it is showing around 112-114 which is about right for what I am doing.
Can anyone explain what is happening I emailed Polar but not very helpful. Would buy one of the watch type monitors but eyes not too good close up
Belt-type HRM's require a good electrical contact with your skin to give accurate results. Dry skin doesn't provide that connectivity, so your monitor tends to fluctuate when you start running. The accuracy improves quite a bit, though, once you've worked up a sweat.
With the hand-grip monitors, you're probably holding the monitor in a tighter grip, and that's why your accuracy is better even early in the run.
Oh roo roooo!
So what you can do to try to fix the problem is pre-wet the sensors on the HRM chest belt. I just use tap water, but I know they sell gels specifically for this purpose. Also make sure it's tight enough to have good contact--mine seems to loosen up after a while and I have to tighten it a smidge every so often. That will likely take care of it for you.
(wet the strap, as RLeMart & HoneyPig mention...)
Otherwise, I've heard of people who have had problems when wearing the HR monitor upside down. Don't know why it causes issues, but apparently, it matters.

And try the HRM with some different shirts...
I have connectivity problems while wearing some tight fitting technic shirts, especially in dry and cold weather (dry and cold won't aply to you indoor-circumstances I guess, but give it a try while wearing it with some different shirts.)

I got a polar model heart monitor last year when I tried out p90x and it was nothing but problems! The key is you have to have the electrodes soaking wet and keep them really wet throughout the workout. I also know what your talking about with the random 60-70 HR issue. Mine did this all the time when it lost connectivity. It was really anoying because it would always through the all important "average HR" value way off.
I dont know if garmin sells a stand alone HR monitor, but if they do GET IT. When I got my forerunner 410 this year I was completely amazed how much better the HR monitor worked. I never have to wet it at all, and I have never lost signal. Its also a lot smaller and doesn't look rediculous poking through your shirt.
I never used the polar because it was such a fuss to get working right.
This is really basic, but ... you're wearing the heart-rate strap UNDER your shirt, right? Not on top?

My Garmin never did work right until I prewet it AND used HRM goop.
