WARNING
When creating new equations or varying any of the branched model values
do not replace any of the default values but create a new record in the
database.
1.2.1 Energy
Models
The different energy models available to analyse recordings are controlled by
entries in the paee table of the settings database. If you wish to experiment with
a new model or combinations of existing models, you may add new rows to this
database. You should do this with some caution, and we can make no guarantee
as to the energy expenditure results you will gain. You must not alter the existing
rows.
Each row added to the table will result in a new energy model being added to the
list available within the software. Most of the columns needed for each entry are
shown in the diagram on the following page, linked to the corresponding entries
in the branched model parameters window. The remaining columns are
explained immediately below:
•
ViewOrder:
This number determines the order in which the models will
be displayed within the software. If adding a new model, simply choose a
higher number, for example starting from 100.
•
ActiheartFlex:
This controls the “flex point” value of activity counts where
the EE prediction switches between a linear projection from the origin to
the Act EE equation.
•
HRflex:
This controls the “flex point” value of heart rate where the EE
prediction switches between a linear projection from the origin to the HR
EE equation.
•
Jap2007Activity:
This controls whether the piecewise linear activity to
EE model from the JAP2007 paper will be used.
•
common:
This determines
whether the model appears when “Show
Common Models” is selected.
