FitBit

October 4, 2008

As many of you already know i’ve been back and forth with a calorie burning monitor.  The latest two have been Polar or Bodybugg. Well a new monitor is set to hit the scene very soon. It is called the FitBit and it looks promising.

From the website:

You can wear the Fitbit Tracker loosely in your pocket, clipped to your pants, shirt, bra or to your wrist when you are sleeping. You can wear it all day!

The Fitbit Tracker is wireless. Walk within 25-50ft of the provided basestation and your data will be automatically uploaded to the Fitbit website. The auto-sync software runs on both Macs and PC’s.

View calories, steps and distance on the Fitbit Tracker itself. You can login to the Fitbit website to see even more detailed data and also participate in collaborative fitness goals with friends, family and co-workers.

So what makes it promising?

  • size- it’s very small, and with a built in clip (think almost like the new ipod shuffle) you could be wearing it, and no one would even know.
  • price – $99 puts it cheaper than the others and (atleast for the first few months) NO SUBSCRIPTION fee to use the website!!! this means your not paying $250 and then another $12-20 bucks a month.
  • wireless – dont have to worry about plugging it in

So what are it’s drawbacks?

  • the main on is it only uses an accelerometer to track your movements… this means it won’t always be as accurate in your calories burned.
  • No heart rate – again because it only uses the accelerometer you don’t get your heart rate during exercise.
  • Extra fees – they aren’t clear if the no subscription is forever or only for a few months or years.
  • New company – no track record.

I will let you know when i have more information on this product, it looks as though they are trying to get them out about December/January which is when the V3 bodybugg is to be released… interesting.

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
eliminated.

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….
