ISU researchers study accuracy of fitness trackers

whether walking across campus or working out
at the gym activity bands are an easy way to track
your steps heart rate calories burn because of the popularity of these
consumer monitors Iowa State university researchers want to know how accurately
the band’s measure different activities all the constant reminder they have
their own apps so I can track in real time graduate research assistant led
this latest round of testing Participants like Joe Ely wore the four wristbands
and 2 research monitors including this portable metabolic device which provides
a benchmark to measure the accuracy of the consumer models rate of error ranged from 15 to 30
percent from the monitors even though the accuracy might not be what we’d like
it to be it’s on par with what some of the research grade monitors are
providing the overall top performer was the body MediaCore one of the research
monitors while the misfit shine had the greatest rate of error researchers say
that the fitbit Flex Nike FuelBand St in the jaw bone up 24 all had reasonable
accuracy levels however the results vary greatly when measuring specific
activities such as working at your desk we spend lots of time for sedentary activities sitting around watching TV watching watching computers
and reading estimating the sedentary behavior and expenditure
the monitors were not as accurate or sedentary activity but the rate oferror
was even greater for resistance training researchers say this is not surprising
because the monitors are designed to capture acceleration in body movement
in weight lifting your standing in the same place and you’re lifting objects in your hands
moving fairly slow but you’re you’re doing a lot of work to study shows there
is room for improvement researchers say more important than
accuracy is understanding how the monitors change behavior amount of error
is a mute point if the band is left on the kitchen
counter where people wearing one are not getting up and moving more for ISU News Service, I’m Angie Hunt


  1. I don't think design issues such as reporting inflated Calories Burned is ever a moot point — in all such situations, the user is learning (whether formally or via an intuitive understanding of reality). Why deliberately send false data??? If your algorithm does not spit out a Calorie Count, then do not display it as such!! Instead, name it something pseudo-sciency, like Nike Fuel or Misfit Points.

  2. Please provide an ID for the publication.

  3. NERDS!!!na jk you guys aight
