Data Analysis
Analysis section shows the number of walking and running episodes, the total number of steps
taken across all episodes and the maximum number of steps taken in an episode of walking and
running. Additionally 10
th
, 50
th
and 90
th
percentiles for steps taken and average cadence are
reported over all the episodes. You can switch between walking and running by clicking on the
‘Walking’ or ‘Running’ radio buttons. Energy Expenditure is displayed over the duration of the
monitoring period and can be visualized as METS or Calories/hr. A MET, or metabolic equivalent, is
a measure of the energy expended during physical activity expressed as a ratio of metabolic rate for
a given task to a reference metabolic rate during quiet sitting. One MET is equivalent to one Calorie
per kg body weight per hour. Note: 1 kcal = 1 Calorie = 1000 calories. Energy expenditure
calculations in PAMWare are based on movement intensities measured by the sensor and task
specific metabolic equivalents as reported in Compendium of Physical Activities: an update of
activity codes and MET intensities (Medicine and Science in Sports and Exercise, 2000; 32
(Suppl):S498-S516).
Exporting Data
Both analyzed and raw data can be exported. To export analyzed data to an excel file, click the
‘Export Result’ button at the top of the ‘Data Visualization’ pane. You can view the raw data at any
time by clicking the ‘Show Raw Data’ button at the top right-hand corner of this pane. To export the
raw data as DAT or CSV files, click the ‘Export Data’ button at the top of the ‘Data Visualization’ pane
when viewing Raw Data.
