What is the Technology Used to Measure the Activity with the Polar Active?
In Polar activity monitors, one dimensional (1D) acceleration is measured.
When comparing 1D to 3D measurement in accelerometers in general, it has been shown that 3D does not significantly improve the prediction of energy expenditure compared to 1D.
In Polar devices, 1D also provides longer battery lifetime.
