Data Filters (1/2)
Filter Data
Data can be ltered for any graphed session, modifying what is displayed
according to multiple parameter values. Filters can be applied to 8 parameters
only, selected from the Filter Variable pull down list. 21 Threshold Variables
are available.
Examples
∙
Use Heart Rate Condence to lter heart rate to remove excessively high
heart rate values caused by ECG noise, and interpolate - this will give more
realistic values for calories burned, intensity and load calculations.
∙
Set realistic upper limits for Speed from GPS data and set to null any values
greater than these, which may be outliers caused by poor GPS satellite
reception.
Action - Interpolate or Null?
Interpolate draws a straight line between points on either side of the
interpolated segment. Null sets no value; the graph trace will show a vertical
line either side of the null segment.
Choice of null or interpolate will depend on the scenario. The example below
shows the Subject 01 Demo Mountain Bike race available in Analysis (date
stamp 16 Sep 2001).
∙
Unltered data, showing HR (solid trace) vs. HR Condence. HR Condence
drops to zero soon after HR climbs above 200 beats per minute, most likely
caused by too-dry sensor pads. This recties itself eventually, as the
subject perspires.
∙
The same data with action Interpolate, when HR Condence < 25%
∙
The same data with action Null when HR Condence < 25%
∙
In the above scenario it would not be appropriate to set null HR values. The
user must decide whether unltered or interpolated data best represents
the subject’s actual HR. Interpolate is not ideal, but a better compromise
than null, or the original articially high values.
