Leaping and Accelerometry: A Theoretical Approach [PDF]

Nature Precedings, 2008
AbstractAccelerometry has always been a popular method of monitoring locomotor activity but its use is becoming more widespread due to the easy availability of low cost, low power sensors. However one of the major problems with interpreting accelerometer data is that rotation of the sensor alters the output and obtaining independent orientation ...

Validity of hip-mounted uniaxial accelerometry with heart rate monitoring [PDF]

, 2012
One of the aims of Identification and Prevention of Dietary- and Lifestyle-Induced Health Effects in Children and Infants (IDEFICS) validation study is to validate field measures of physical activity (PA) and energy expenditure (EE) in young children ...

[Physical activity assessment using accelerometry].

Revue d'epidemiologie et de sante publique, 2019
Physical activity is an important determinant of health in children and adults. Assessment of physical activity is therefore an important factor in the promotion of health and in several childhood and adulthood pathological situations. Physical activity can be estimated by various methods: pedometry, heart rate monitoring, questionnaires, the doubly ...

Sleep assessment using accelerometry: Not all algorithms are equal

Sleep Research
Study objectives Accelerometry devices are increasingly used to assess sleep. However, whether different algorithms provide consistent estimates remains uncertain. This study compared sleep parameters derived from two accelerometry‐based algorithms and a

Association between ADHD symptoms and device-measured physical activity and sedentary behavior in childhood: A population-based twin study. [PDF]

JCPP Adv
Abstract Background Attention‐deficit/hyperactivity disorder (ADHD) symptoms are associated with adverse health outcomes; this may be partially due to unhealthy lifestyle factors such as low physical activity (PA) and high sedentary behavior (SED). However, this association remains unclear.

Comparison of accelerometry cut points for physical activity and sedentary behavior in pre-school children : a validation study [PDF]

, 2012
This study compared accelerometry cut points for sedentary behavior, light and moderate to vigorous intensity activity (MVPA) against a criterion measure, the Children’s Activity Rating Scale (CARS), in preschool children.

Beyond Moderate to Vigorous Physical Activity (MVPA): Why Physical Activity Surveillance May Be Failing Culturally and Linguistically Diverse (CALD) Girls in Australia. [PDF]

Health Promot J Austr
ABSTRACT Physical inactivity among culturally and linguistically diverse (CALD) girls in Australia is typically framed as a participation problem. However, emerging evidence suggests it is equally a measurement problem. Current surveillance systems rely heavily on self‐report tools, sport‐centric participation models and generic moderate‐to‐vigorous ...

Correlates of agreement between accelerometry and self-reported physical activity [PDF]

, 2016
Purpose: Understanding factors that influence accurate assessment of physical activity (PA) and sedentary behavior (SB) is important to measurement development, epidemiologic studies, and interventions. This study examined agreement between self-reported

Multicolor particle shadow accelerometry [PDF]

Measurement Science and Technology, 2015
This paper describes the extension of multicolor particle shadow velocimetry (CPSV) to the measurement of local acceleration in an Eulerian frame of reference. A validation experiment was conducted on a pendulous disk undergoing unsteady rigid body rotation.

Concurrent validity of a developed accelerometry-based device for postural sway assessment [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2020
Postural control is one factor related to falls. Many instruments are available to objectively evaluate postural control performance. However, feasibility and applicability is limited by setting and financial restraints.
