Purpose To determine the effect of implementing the Nutrition and Physical Activity Self Assessment for Child Care (NAPSACC) program on objectively measured physical activity during the school day in twenty-six licensed daycare centers throughout Louisiana randomized to either treatment (intervention; N=13) or control (no intervention; N = 13) conditions. Subjects: Pre-school children, 3...
Introduction:
Experts recommend children spend more time playing outdoors. The ambient light sensor of the ActiGraph GT3X+ provides lux measurements. A lux is the International System’s unit of illumination, equivalent to one lumen per square meter. Few studies have established a lux threshold for determining whether a child ...
Introduction Compensatory changes in non-exercise physical activity (NEPA) in response to an aerobic exercise training program may impact weight loss.
Purpose To examine changes in NEPA in response to 2 levels of aerobic exercise training.
Methods Ninety-two overweight/obese (BMI 25-39.9) sedentary young adults (18-30 yrs.) completed (i.e. ≥ 90% scheduled exercise ...
Purpose Recess and other school-based physical activity (PA) programs are important avenues for school children to participate in PA beyond physical education at school (NASPE, 2006). However, the quantification of the contributions of these programs, as compared with physical education, remains largely unexplored. This study was designed to compare young children’...
Objective The purpose of this study was to examine the relationship between sleep (duration and quality) and diet quality among young adult women. Subjects: Three-hundred seventy-five women (18-24 years) were recruited to participate in the study.
Measurement Each participant wore an actigraph for 7 consecutive nights to measure sleep. Sleep logs ...
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 ...
