A Brief Survey of Physical Activity Monitoring Devices

High caloric  intake and  low physical activities are recognized as key causes behind the dramatic rise  in obesity, diabetes and other chronic health conditions over the past few decades. Accurate monitoring  of  physical  activities  and  energy  expenditure  is  critical  to  test  the  effectiveness  of current  and  emerging  clinical  therapies.  This  report  provides  a  brief  overview  of  commercially available devices that monitor physical activities. Many of these devices can be effectively used in metabolic assessment, behavior therapy, and weight management, becoming an essential part of the solution to diabetes, obesity and chronic diseases.  In this report, we review the following: 1) the  function  of  pedometers  and  accelerometers,  2)  taxonomy  based  on  their  mechanisms, measurements, product forms, and data portability. and 3) the role of personal devices integrated with  pedometers  and  complex  monitoring  devices  with  multiple  sensors  in  assessing  energy expenditure.This report closes with conclusions based on our study..
