The links between increased participation in Physical Activity (PA) and improvements in
health are well established. As this body of evidence has grown, so too has the search for …

Wearable devices represent one of the most popular trends in health and fitness. Rapid
advances in wearable technology present a dizzying display of possible functions: from …

The use of physical activity monitors in population-based research has increased
dramatically in the past decade. In this report we review the major purpose for using physical …

This article describes an investigation to determine the optimal placement of accelerometers
for the purpose of detecting a range of everyday activities. The paper investigates the effect …

Current public health guidelines on physical activity and sleep duration are limited by a
reliance on subjective self-reported evidence. Using data from simple wrist-worn activity …

The ability to assess energy expenditure (EE) and estimate physical activity (PA) in free-
living individuals is extremely important in the global context of non-communicable diseases …

Wrist accelerometers are being used in population level surveillance of physical activity (PA)
but more research is needed to evaluate their validity for correctly classifying types of PA …

A sedentary lifestyle and lack of physical activity are well-established risk factors for chronic
disease and adverse health outcomes. Thus, there is enormous interest in measuring …

BACKGROUND: Physical activity may be defined broadly as" all bodily actions produced by
the contraction of skeletal muscle that increase energy expenditure above basal level." …

We have recently developed a simple algorithm for the classification of household and
locomotive activities using the ratio of unfiltered to filtered synthetic acceleration (gravity …
