Actiheart User Manual 5.1.31 (Jun 2022)
51
There are a number of options for controlling the calculation of energy
expenditure calibration from the step test observations. These are selectable
options above the “Save” button. We recommend that for new projects the
“JAP2007 – improved” option is chosen. The “Original” option refers to the
calibration included with the first version of the Step test software. It should only
be chosen by those who need to continue with backwards-compatible work. The
“JAP2007” option refers to a calibration using improved information from the
paper referenced in A
ppendix 2. The “JAP2007 – improved” option is from the
same results, but with validated scaling for varying step height and step tests
where the user has stopped well before the eight minute mark.
The activity equation is provided solely for information. It is not used to derive an
individual calibration based on activity and therefore it has no effect on the
calculation of energy expenditure. The heart rate equation on the other hand
forms the basis of the derivation of a PAI-HR calibration equation which can be
used in the branched model in lieu of the group equations.
4.5.8 Setting-Up
Multiple Users
It is possible set up more than one user to do the Step Test simultaneously. This
is achieved by setting up the required number of Actihearts individually and
setting them all to a synchronous start time. Multiple physical steps will be
required.
4.5.9 Marking Bad
HR data
When manually reviewing the R wave graph and regions of bad signal are found,
it is possible to manually mark a 15 second block as bad data if you do not wish it
to be included in the analysis. This may be achieved by using the ‘Bad HR data’
checkbox below the R wave graph; a large red ‘X’ will appear on the graph to
show it is marked as bad data. A small ‘X’ will also appear at the top of the upper
graph. It is possible to select/de-select each of these marked blocks by double-
clicking on the small red ‘X’ on the upper graph.
4.5.10 Copying Data
for a User
There are 2 possible options for copying data to the clipboard for importation and
analysis into an external program such as Excel:
1.
Copy Detailed Data:
Provides an export with header information and an
epoch-by-epoch, time stamped listing of activity and Heart Rate data with
IBI and HRV values.
2.
Copy Summary Row:
Provides a single row export of the results for the
current analysis.
4.5.11 Printing and
Previewing
It is possible to preview or print the step test report which contains a results
summary and graphs of the activity and HR, a graph of the ECG for the currently
selected 15 second block, a graph of the Activity for the currently selected 15
second block and a graph of the Heart rate and Activity Energy Expenditure.
Select preview to view the report on screen, select print to send the report to the
printer.
