Recording human activity can be achieved by various methods.
To monitor energy expenditure over long periods,
Actical is the preferred tool as
it will record daily activity using a compact tri axial
accelerometer and built-in pedometer typically worn on the hip.
Using a proprietary algorithm, energy expenditure is calculated
and reported for every minute, hour, day, week and the complete record.
Actiheart is another
tool that will calculate energy expenditure based on accelerometry data complemented
with heart rate
recordings.
Finally for those who want to derive their own algorithm or have
access to specialize analysis software,
Actiwave Cardio
will collected ECG and accelerometry data
