4.3.2
Selecting an
Energy
Model
Before you can view a recording and analyse it, you first need to select the
“Energy Model” that you wish to apply to the analysis from the drop-down list. If
you select one of the group calibration models then all recordings will be
displayed. However, if you select an ind
ividual calibration model e.g. “Step-test
HR” or “Individual HR Cal” then only the recordings that contain an individual
calibration will be displayed. The energy expenditure calculation will then be
based on the selected variant.
The available energy models are split into two groups - the four common models,
which will be appropriate for most new users, and other modes which are
provided either for backwards compatibility or more specialised uses. The
common modes are:
Group Cal JAP2007:
This model uses a group calibration for heart rate and
activity. We recommend it for any new analysis work on adults, where you do not
wish to perform a step test on each participant.
Group Cal Jap2007/Step HR:
This model uses the individual users' step test
results to calibrate for heart rate, but the same group calibration for movement as
above. We recommend this for greater absolute accuracy, where it is possible to
perform a step test on each participant. Note that the step test is not used for
movement calibration, because this is very variable per-activity and adjusting
based on a step test alone would be inadvisable.
Child: Group Act/Group HR:
This model uses group calibration measurements
from a test performed on children. We recommend it for any new analysis work
on children, and it does not require individual testing for each participant.
Child: Group Act/Ind HR:
This model uses group calibration measurements
from children for movement, but the individual calibration table for relating HR to
EE for that user. We recommend this for analysis of children where you have the
capability to perform HR to EE calibration measurements for relevant activities on
each child.
Note that regardless of the energy model used, per-user information such as
weight, sex, age, height and sleeping heart rate must still be entered accurately.
