HRM monitor and heart rate

[Rob]

Is it real that a hear rate can drop from 157 to 140 in 5 sec? Or is it an anomaly? As I am still
getting accustomed to HR monitor I find it surprising that there is such a big drop in such a short
time! I have experience this also with climbs.

I'd say after 3 years of using mine, it is a bit steep of a drop, however in saying that, I
sometimes 'play' with my breathing after a run, and see just how much I can get it to drop in a
short amount of time, by doing things such as holding my breath or concentrating really hard on
dropping it (breathing rate). I would suggest it was a reading where the contact points on the strap
have slipped giving a slight false reading.

I read that Miguel Induran<SP> was once tested at dropping from 180 to 60 in something on
the order of 60-90 secs. This was from a full out to a stand still. If it were 60 secs thats
a drop of 2 beats per second, a little over half of what your experinacing in 5 seconds
except his continued for 60 secs. I don't think a drop of 17 BPM in 5 secs is a big deal,
particularly if going from Running to standing. It may be a bit misleading, IOW I'm not sure
how the HR monitor actually figures out BPM. Mine has adjustable sampling rates from every 3
secs, 10 secs or 60 secs. I'm sure there is some room for calcualtion rounding/error in
there somewhere particularly in a 5 sec sample. I haven't actually checked my HR drop. If I
can remember I'll look at some of my files and see what it does.

most likely the contact is poor. and it sort of just makes up a reading. every time i wear mine i'll
see readings that i know are false... way too high usually. i just press the strap to my chest for a
few seconds and watch the number average down to a stable reading.

after using it a few times you'll know what your HR is. just by how fast you're going. how hard it
feels. how hard you're breathing.. you'll just know. so, to learn that, listen to your body when
you're wearing the HR monitor. see how you can drop 5 bpm just by breathing deeper. or how the HR
goes up while you change running form. or wipe your face. ...thehick

Being a runner, I'm willing to bet that's not all you play with regularly.

The usual advice is to wet the back of the sender (active part of the = strap).

My advice is to wet the chest instead. Works better for me.
