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
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’...
Purpose
To evaluate the multi-group and longitudinal invariance of ANNs to predict physical activity (PA) type and PA energy expenditure (METs) in youth.
Methods
The study was conducted at two sites. Site 1 (S1) served as the training and testing sample and comprised 100 youth mean age 11.0 ± 2.7 y. Site 2 (S2) served as ...
Purpose A number of recent studies have found associations between the characteristics of schoolyards and the level of PA of schoolchildren using the schoolyards. Based on these findings, it seems likely that making schoolyards more attractive will help to increase the total amount of PA among schoolchildren. Before starting our ...
Purpose
Published experiences of using accelerometers in very young children are scarce. This study tested the usability of one accelerometer type, ActiGraph GT3X, in assessing free-living physical activity of 1.5 year-old Malawian children.
Methods
Fifty-two Malawian children [23 boys, mean age 17.0 months (range 16.0 – 18.5), mean HAZ -0.83, mean WHZ 0.08] from rural Lungwena ...
Purpose
To inform intervention development by investigating predictors of one-year change in objectively-measured intensity of physical activity (PA) in a cohort of 9-10 year old British school children.
Methods
In a cohort of 753 children in Norfolk (UK) (41.7% male, baseline age (mean±SD): 9.7±0.4 years) PA was measured over 3 or more days ...
