HRM read 229 max??? what????

yup..

Finally got the new Blackburn Delphi 6.0 computer mounted and "calibrated" on my Obera bike. Bit of an ordeal as my drop bar is squashed to make the bar more aerodynamic...

Anyway. took for a short spin today (first ride in about two weeks. busy stressful work plus migrane hanging in for days...)

Interesting stat from the computer.

avg speed :p (sorry too embarassing)
max speed: 38.2 MPH
ride time: 1:38:48
distance: :p time and distance and you can figure out my avg so :p
avg HR: 171 :confused: :confused:
max HR: 229 :confused: :confused:
total climb: 1279ft

It even gave me the grade of my hill climb. 3-6% Wow I didn't think this short ride had that much hill climb.

NOWWW.... what is baffling is my HRM function... When I tried it on the other day, it seemed to be working ok. Buttt the average reading seems to be tad high on today's ride.

6 years ago before my big wreck, I generally kept my heart rate at 80-85% (160bpm-170bpm) and pushing 180bpm for more than a minute would put me in oxygen debt anaerobic state where I would need about 20 minutes to recover.

And today I was running around 170bpm for most of the ride. IN fact the avg reading confirms this. And on the hill climb with 5% grade, my HR bumped to 180-190bpm??? I know I can't hold that kind of rate... So what's going on with my HRM. There were no other riders nearby to interfere with my wireless connection.

My max HR 6 years ago was 204-206 depending on how much sleep I had the day before and how tired I was. And today it registered 229 (don't know what my real max HR today is)?? I thought max HR was supposed to come down with age.

Suggestion as to why the computer gave me a false reading? I know it has to be a false reading. The computer is literally brand spanking new. Got it for xmas of '06. Battery is fresh and not worn out... It hasn't been crashed or jarred violently...

I'll be riding in a group tomorrow. So I'll check my computer again tomorrow. An easy 24 "junk" miler.. ;)

229 - Sounds like your signal transmission went off.

I am often "dead" - either with cardiac arrest (HR=0) or atrial fibrillation (HR=223) on my polar.....

Sometimes "just because", or because my strips aren't soaked properly, or because I am cycling along a train line.

Those high reading usually are related to contact. If the HRM is moving around a bit it will read the electrical signals resulting from movement on your skin and will give a false high reading. See what you can do to improve contact and keep it from moving around.

yeah - mine will sometimes get strange readings around electric or invisible fences and down near the grocery store- I think its probably the cart retention sysem (works like an invisible fence and brings a "boot" down on one of the cart wheels if you take it outside the store property. It will read out 220 while I am standing still....
Some things make it lose the signal too - under certain powerlines seem to make it cut out.

Went out on a group ride but forgot to reset my computer so. the max heart rate still reads 229... My avg heart rate is still on the high side... all other reading seems to be okay and reasonable. I wonder about the HRM. I do ride by a power plant and I see those cross country transmission lines..

My computer in the past said that I've flat lined bp=0 but never gave me a ridiculously high reading. I've also had erratic reading as Wahine says. but this HRM seems to be pretty steady and hasn't twitched. Atleast when I was looking at it. Oh well

Thought the ride was supposed to have been 25 or so "junk" mile. The group had a change of heart and decided to do some hill work :eek: almost the same hills I did yesterday!!! Well it was a good work out. :D And a fun day.
