Polar pt2

August 4, 2008

So if you haven’t read (previous post) i’ve been going back and forth between BodyBugg and Polar HRM – after polar’s most recent email back… i think i know which one i’m going with:

Here’s my email:

If i was looking for the best device to track my Total Calorie Expenditure
for the entire day (day or night, awake or asleep, working out or resting)
which device would i want?

And Polar’s Reply:

Dear Anomoly,

Thank you for your email.

It is well known that the heart rate tends to overestimate daily energy
expenditure. This is because in everyday life heart rate can be elevated
due to other reasons than physical activity (changes in posture, emotional
factors, mental stress, heavy exercise before). On the other hand, heart
rate is practically never lower than the metabolic cost requires.
Subsequently, energy expenditure estimates tend to be too high in
measurements done over extended periods.

Polar heart rate based caloric equation has been shown to be very accurate
during physical activity (heart rate over 100 bpm). The accuracy is not as
good at low heart rates. Even below 100 bpm it is in the right level if
elevations in heart rate due to other factors than physical activity can be

So in short they confirmed what most had speculated… Heart Rate Monitor’s are decent for Exercise, not great when it comes to everyday calorie expendeture.

So that answers my question, now i just have to find out with the Bodybugg V3 is hitting the market….
