How many days are needed to estimate wrist-worn accelerometry-assessed physical activity during the second trimester in pregnancy?
(Peer reviewed; Journal article, 2019)Background: Objective methods to measure physical activity (PA) can lead to better cross-cultural comparisons, monitoring temporal PA trends, and measuring the effect of interventions. However, when applying this technology ... -
Physical activity levels in adults and elderly from triaxial and uniaxial accelerometry: The Tromsø Study
(Peer reviewed; Journal article, 2019)Introduction: Surveillance of physical activity at the population level increases the knowledge on levels and trends of physical activity, which may support public health initiatives to promote physical activity. Physical ... -
Separating movement and gravity components in an acceleration signal and implications for the assessment of human daily physical activity
(Journal article; Peer reviewed, 2013-04-23)Human body acceleration is often used as an indicator of daily physical activity in epidemiological research. Raw acceleration signals contain three basic components: movement, gravity, and noise. Separation of these becomes ...
