Introduction Recent research shows that too much sitting has negative effects on health and well-being independently from people meeting the current physical activity (PA) recommendations [1]. However sedentary behavior (SB) is still an understudied topic. The aim of this study was to objectively investigate the time spent in sedentary and PA ...
The number of days of pedometer or accelerometer data needed to reliably assess physical activity (PA) is important for research that examines the relationship with health. While this important research has been completed in young to middle-aged adults, data is lacking in older adults. Further, data determining the number of ...
Introduction Accelerometer data provide reliable, valid, and stable measures of physical activity, and also allow for the estimation of sedentary time. Furthermore, as data are date and time-stamped, the outcomes of interventions targeting these behaviors can be explored beyond simple average of change. Methods Stand Up For Your Health [1] was ...
Introduction Cardio-metabolic risk factors are becoming more prevalent in children and adolescents. A lack of moderate-to-vigorous intensity physical activity (MVPA) is an established determinant of cardio-metabolic risk factors in children and adolescents [1]. Less is known about the relationship between sedentary behavior and cardio-metabolic health. Therefore, the objective was to examine ...
Aims Prolonged sedentary time is ubiquitous in developed economies and is associated with an adverse cardio-metabolic risk profile and premature mortality. This study examined the associations of objectively assessed sedentary time and breaks (interruptions) in sedentary time with continuous cardio-metabolic and inflammatory risk biomarkers, and whether these associations varied by ...
Childhood obesity has been attributed to a decline in total energy expenditure (TEE). We measured TEE, physical activity, and sedentary behaviour in a representative sample of young children from Glasgow, UK, at age 3 years (n=78), and we did a follow-up study at age 5 years (n=72). Mean physical activity level (TEE/...
This study examined whether there was a significant seasonal variation in objectively measured habitual physical activity and sedentary behavior in young children. Participants were 209 children who attend nursery in Glasgow, Scotland, and measurements were taken using uniaxial accelerometry over 3 to 6 days. There were small but significant seasonal associations with physical ...
There is increasing public health concern that levels of physical activity in children are extremely low. This study aimed to describe objectively levels of physical activity and sedentary behaviour during the waking hours in a sample of 4-5 year old (median 5.4 years range 4.3, 6.0) rural Irish children (n=41) and to test ...
Background Changes in sedentary behavior may be related to changes in energy intake. Objective The purpose of this study was to investigate how experimental changes in the amount of sedentary behaviors influence energy intake. Design Sixteen non-overweight 12—16-yr-old youth were studied in a within-subject crossover design with three 3-wk phases: ...
Objective To objectively measure habitual physical activity and sedentary behaviour in a clinical sample of obese children and to compare with age- and sex-matched non-obese controls. DESIGN: Pairwise comparison of obese children matched for age and gender with non-obese controls. Subjects A total of 116 obese children (body mass index (BMI)> ...
