Whacking heart rate sensor with handle

[Willy.VdW]

I think the HRM manuals typically say to put the module middle of your chest or, if troubles, a bit on the left.

That' correct, probably because the human heart is located closest to the chest, behind the sternum.
But if the sensor is sensitive enough to register the pulses when worn on the back, this seems a very
solution. Easy to try, no work or cost invloved, just turn the belt and see if it works.

It always surprises me when manufacturers don't foresee issues of this nature. Perhaps I'm asking for too much.

Is there a workaround for this? I sometimes use a Polar H10 and give the sensor a bash every time I pull the handle to my sternum. I've heard that some wear the strap so that the sensor is slightly off centre. Thoughts?

If i wear my Polar HRM i now wear it with the monitor on my back seems to work fine.

Hi Glenn. I tried this tonight and I got either no reading at all or an entirely inaccurate one. However, I'll give it another go tomorrow, with slightly different positioning, and see how I get on. Many thanks.

If that still doesn't work, try connecting the monitor to the chest strap the opposite way. That may or may not help.

I'm late to this thread, but because I've never had problems with the handle being anywhere close to the HRM transmitter, yesterday I made it a point to notice where it is at the end of the drive, and in my case it's well below that. I'd say about +/- 1" of my navel, so no chance of hitting the transmitter.

You mean 1" above your belly button ? That would be too low according to what's recommended, no ?

I think the recommendation is that the strap sits just under the pecs, but people seem to get away with wearing them much lower. I follow an elite marathoner on YouTube who wears his very low. Frankly, if I was running with the strap that low, I'd be afraid of it slipping off.

When I start to run, the belt sometimes slips a bit downward when I exhale.
This only happens during the first few minutes, it stops when the belt becomes sweatty and sticks to my skin.
Wetting the belt beforehand avoids slip and improves instant detection of my heartbeat

Yeah, I always wet the 'electrodes'. Due to injury, my running days are now over, sadly. Very sadly.

That's about where the guy in the upper video in the link below seems to have it. (see at the 0:35 mark)

The gal in lower video is higher.

Hmm the upper video seems to be a veeery relaxed rowing ... I use rowerup.com occasionally and it seems to like it higher (the video on their 1st page shows it too).

Anyway I think that, thanks to bloody Murphy, the recommended handle height at the end of the drive is ... exactly where your HRM should be

I'm probably about the same, maybe a very little bit higher, but it is lower than the solar plexus where my HRM sits.

I'm guessing the lady in the video is higher up due to height? It's roughly a straight line in the stroke, so upper body height will make a difference.

My stroke ends about six inches above the HR transmitter around the SC joint.
