Purpose Accelerometers could potentially be used to assess physical activity and sleep using the same monitor; however, two different positions are typically used for the assessment of physical activity and sleep (waist and wrist, respectively). The aim of this study is to evaluate the concordance between wrist- and waist-worn Actigraphs ...
Background:
The aim of this study is to describe the relationship between objective measures of sleep, physical activity and BMI in Swedish pre-adolescents. The day-to-day association between physical activity and sleep quality as well as week-day and weekend pattern of sleep is also described.
Method:
We conducted a cross sectional ...
Background Accelerometers are now the method of choice to objectively assess activity in young children. While numerous cut-points exist for preschoolers, cut points for children aged 1-3 years are limited.
Purpose To determine ActiGraph GT1M cut-points for sedentary (SED), light (LPA) and moderate-vigorous physical activity (MVPA) in toddlers.
Methods ...
The Physical Activity Questionnaires (PAQ-Children and PAQ-Adolescents) are
widely used to assess youth physical activity patterns but a limitation is that they do
not provide information about time spent in moderate-to-vigorous physical activity
(MVPA).
Purpose The purpose of this study was to calibrate in- and out-of-school activity
items of the ...
Various sets of prediction equations for the Actigraph have been developed to estimate
energy expenditure (EE) in youth, but there is no consensus about the best approach. A
set of two 2-regression models (2RM) have been proposed as alternative to traditional
single regression models (1RM), but they have not been ...
Little research exists assessing parent and child physical activity (PA) in relation to
parental knowledge of PA recommendations.
Purpose To subjectively and objectively assess parent and child PA and parental
knowledge of the moderate-to-vigorous physical activity (MVPA) guidelines for adults
and children.
Methods Participants were 20 parent-child pairs (child age 8.9 ± 1.9 y). ...
Moderate-to-vigorous physical activity (MVPA) and executive function (EF), the
ability to organize thoughts and make decisions, have been identified as contributors
to cognitive ability and academic success in school-aged children. These associations
have not been established in young children.
Purpose To determine the influence of MVPA and EF on school ...
Purpose To evaluate an unstructured afterschool physical activity (PA) program for
elementary school students.
Methods PA levels of 3rd, 4th, and 5th grade students (N=205) at four lowincome
elementary schools (67-79% free and reduced lunches) were cross-sectionally
assessed during an unstructured afterschool PA program. Assessments at each school
were conducted ...
Background:
There is evidence to suggest that increasing physical activity (PA) improves academic achievement (AA) in children and that aerobic fitness is associated with both cognitive function and AA. However, it is not known how these variables are interrelated and analyses with adequate control for socioeconomic variables are needed. It ...
Health authorities recommend that schoolchildren should be physically active for at
least 60 minutes every day. The physical activity (PA) level of Norwegian children and
youth with ethnic minority background is not well known.
Purpose The purpose of this study was to monitor the PA level of children and
youth with ...
