Objective
To evaluate the classification accuracy of five ActiGraph moderate-to-vigorous physical activity (MVPA) cut-point definitions in pre-school children using energy expenditure measured by whole-room calorimetry as the criterion measure.
Methods
20 children aged 4-6 years (5.1 ± 0.8years) completed a ~50 min whole-room calorimeter protocol involving age-appropriate moderate and vigorous physical activities (eg. rumling ...
Objective
To investigate the single and combined associations of physical activity (PA), body mass index (BMI), and sleep duration with clustering of cardiovascular disease risk markers in healthy children.
Methods
We did a cross-sectional pilot-study of 74 Danish school children aged 8-11 years. Risk factors included in a continuous metabolic syndrome ...
Introduction
physical activity (PA) is perceived to be a key determinant of childhood adiposity. This study objectively characterizes the daily PA of 7-year-olds and relates it to waking time, intensity, UK recommendations and body fat.
Methods and Participants
MTI-Actigraph accelerometers were worn by 129 (88) healthy boys (girls) for seven days. Calibration ...
Introduction
There is much interest in children’s physical activity (PA), but little understanding of its control. The evidence that total activity levels could be increased by the provision of greater opportunity for physical activity is lacking.
Methods and Participants
MTI-Actigraph accelerometers recorded weekly PA in two groups of healthy ...
Purpose
Sedentary behaviour is known to have a detrimental effect on health. However, the manner in which is it accumulated may also be important. Therefore, we examined the association of daily sedentary time and breaks in sedentary time with various markers of cardio-metabolic risk.
Methods
Cross-sectional analysis using 725 participants from ...
Purpose
To describe the patterns of sedentary behaviour (SB) across the day and explore relationships with body composition and fitness.
Methods
249 children (mean age 8.8 yrs; 56% female) wore an ActiGraph GT1M accelerometer for 7 days, completed a 20m shuttle run fitness test and had triceps and subscapular skinfolds measured. SB was ...
Purpose
To evaluate the influences of social and physical environmental factors within the home on preschoolers’ PA.
Methods
GT1M Actigraph data for 7 days were obtained in a random sample of 70 boys and 71 girls (5.4 years ± 0.3). Social (parental attitudes, knowledge, social support, rules) and physical environmental factors (play space, TV and ...
Purpose
To examine the effects of short bouts of structured physical activity (PA) on during-school total PA in lower socioeconomic status preschoolers.
Methods
Ten preschool centers serving low-income families will be recruited and randomly assigned to one of two groups. Treatment preschools will implement the Tutti Fruitti Instant Recess intervention ...
Purpose
Children’s independent mobility may correlate with physical activity; however it may also expose them to more sweet and fast food shops, potentially explaining the caloric intake in young people. This cross-sectional study investigated whether independent mobility is preadolescents was related to caloric intake.
Methods
Six hundred and thirty ...
Purpose
Low levels of physical activity (PA) have been associated with increased risk of child overweight. Multiple studies show that young children are not getting the recommended 60 minutes of PA during their 8-hour day in childcare. (Reilly, 2010) This study will explored whether time spent in childcare is related to children’...
