Purpose To examine the energy balance pathways of diet and physical activity under conditions of acute sleep deprivation in normal-weight and obese women.
Methods In counter-balanced fashion, 22 normal-weight (30.9±9.5 yrs, 22.0±1.6 kg/m2) and 18 obese (29.7±10.7 yrs, 36.4±5.3 kg/m2) women, with a consistent sleep-wake cycle, completed two separate free-living sleep conditions (Condition 1: one ...
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 ...
Accelerometers have the advantage of providing objective measures of both physical activity performed at various intensities and of sedentary time. ActiGraph accelerometers are widely used, however with technological advancements new models are periodically released. The GT3X is the most recent model. Although research has shown previous ActiGraph models to ...
The pattern of physical activity in Hungarian adults might provide information on potential obesity prevention strategies. In preparation for a region assessment of physical activity (PA), placement of an activity monitor were studied in leu of the changes that the NHANES protocol has in the location of the ActiGraph monitors ...
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 ...
Purpose To examine the accuracy of three measurement devices (ActiGraph
GT3x+, ActivPAL, and Sensewear Armband) in assessing sedentary behavior and
light-intensity physical activity (PA) against a referent measure of oxygen uptake
(Oxycon Mobile).
Methods 16 adults (8 males, 8 females) wore the four measurement devices
while performing 7 activities (walking at 1.0 mph, 1.5 mph, 2.0 ...
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). ...
Objective The purpose of this study was to examine the effect that sleep duration and quality has on next day physical activity among a population of young adult women. Subjects: Three-hundred and seventy-five women (18-24 yrs) were recruited to participate in the study.
Measurements Each participant wore an accelerometer for 7 ...
The International Physical Activity Questionnaire (IPAQ) is one of the most widely used questionnaires to assess physical activity (PA). Validation studies for the IPAQ have been executed, but still there is a need for studies comparing absolute values between IPAQ and accelerometer in large population studies.
Purpose:
To compare PA ...
