Re: Heartrate Threshold

Hello Frank 
My guess is that something is loose to cause those extremely high
readings.  I have seen that happen and
tightening my girth, cleaning the tips of the wires that plug into the
electrodes, using more gel, duct-taping the snaps of the leads onto the
transmitter, etc. fixed it.

When everything is right I have trouble with getting the heart rate up as
high as 200 on the biggest mountain climbs with several different fit
endurance horses.  Even at a wide open gallop I cannot get the
heart rate to stay much above 180-190 for very long at all.  Most Arabs
are anaerobic well below this rate and cannot go for long in that state.
