Activity Only or
Heart Rate Only
Mode
This is a special case of the Branched Model where EE is estimated using either
the Activity data or the HR data. In this case the regression equations relating
only to Act (PAI-Act) or only to HR (PAI-HR) are used. The weighting (P1, P2, P3
and P4) for the various modes is as follows:
NB: HR only mode is useful for any activity, not just walking and running,
where the intensity is such that the HR is above the Flex HR
Individual
Calibration
Group calibration is an approximation for a range of individual fitness levels.
Heart Rate above sleep HRaS based on individual sleeping HR is used to reduce
error but individual calibration is more accurate. Individual calibration equations
may be used in the Actiheart instead of the default group calibration ones. The
user may derive these values in the usual way by means of a treadmill test as
described previously. A typical calibration curve is shown below.
For convenience the AH includes a built-in step
–test protocol which can be used
for deriving the individual HR-PAI relationship in the field. The Step Test also
provides an estimate of VO2 max. Please see
Appendix 4 for more information
about the Step Test.
