Background School recess provides an important opportunity for children to engage in physical activity. Previous studies indicate that children and adults of South Asian origin are less active than other ethnic groups in the United Kingdom, but have not investigated whether activity differs within the shared school environment. The aim ...
Purpose Examine whether nonbout physical activity (i.e., <10 minutes' duration of physical activity [PA]) demonstrates a stronger association with health outcomes than bout physical activity (i.e., ≥10 minutes' duration).
Design Cross-sectional study.
Setting NHANES 2003–2006.
Subjects A total of 6321 participants ranging in age from 18 to 85 years.
Measures Objectively measured PA ...
Aims Worldwide levels of daily physical activity (PA) in children are low. This has negative health consequences. Schools have been recognized as key settings to promote PA. This study evaluates the effectiveness of the playground programme PLAYgrounds on increasing PA.
Methods PLAYgrounds was evaluated by a controlled trial, with a ...
Background The magnitude of the association between physical activity (PA) and obesity has been difficult to establish using questionnaires. The aim of the study was to evaluate patterns of PA across BMI-defined weight categories and to examine the independent contribution of PA on weight status, using accelerometers.
Methods The study ...
Background Physical activity is essential for older peoples’ physical and mental health and for maintaining independence. Guidelines recommend at least 150 minutes weekly, of at least moderate intensity physical activity, with activity on most days. Older people’s most common physical activity is walking, light intensity if strolling, moderate if brisker. ...
Background:
Being outdoors may have health benefits including being more physically active. Understanding the relationship between outdoor time and health is hampered by the difficulty of measuring outdoor time.
Purpose:
To examine the accuracy and validity of light-sensor and GPS methods for quantifying outdoor time among those aged 3-5 years ...
Aims
Understanding trends and tracking of children's physical activity (PA) could help to optimise the type and timing of interventions designed to make children more active. The aims of this longitudinal study were to establish the age at which PA levels begin to fall and to determine whether inactivity in ...
Aim The weather may be a barrier to physical activity but objective assessment of this hypothesis is scarce. This study evaluated the effect of temperature and rainfall on the daily physical activity of Danish preschool children. Furthermore within-day variability in physical activity was studied for both weekend and weekdays.
Methods ...
Aim
To investigate eight-year changes in fatness, fitness and physical activity in a cohort of Icelandic children by comparing measurements conducted at two different time points.
Methods
In 2003 a total of 489, 9-year-olds participated in a study called Lifestyle of 9 and 15 year-old Icelanders. A total of 258 from this cohort were recruited ...
Introduction Data on physical activity levels of adolescents are mostly derived from self-reported instruments, and the vast majority of studies using objective measures are from high-income countries. The aim of this study was to describe the patterns of objectively measured physical activity in Brazilian adolescents.
Methods In 2004–2005 (mean age of 13.3 ...
