The aim of die present study was to evaluate different aspects of a device designed to monitor physical activity. Measurements of different axes and placement of the monitor were rested using a treadmill with ranging increments in incline or speed. The monitor was also used to assess the level of ...
The purpose of this study was to analyze physical activity (PA) levels in Grade 3 boys and girls during the school day Participants (281 M, 284 F) wore accelerometers (CSA, Inc.) for 7 consecutive days. Time spent in moderate (3-5.9 MET) and vigorous (> 6 MET) PA was determined BMI was calculated from standard measures of ...
This study analyzed physical activity (PA) levels during the weekday vs. weekend in boys and girls of normal weight, those at risk for overweight, and those who were over-weight Students in Grades 3 (n = 565), 7 (n = 557), and 11 (n = 520) wore accelerometers (CSA, Inc.) for 7 consecutive days Time spent in moderate (3-5 9 MET) and ...
Although engagement in social interactions is one of the key diagnostic features of autism spectrum disorders (ASDs), few studies have examined if social engagement related to physical activity of children with ASD. Age is another variable of interest to researchers studying behaviors, but has not been explored in physical activity ...
Measurement of physical activity in young children must be objective, since self or parental reports are not valid The advent of accelerometry has provided a practical and accurate means of objectively assessing engagement in habitual physical activity and inactivity (sedentary behavior) suitable even in young children. However; there is a ...
Objective To explore the association between measures of insulin resistance with objectively assessed physical activity. Design School-based, cross-sectional study. Subjects A randomly selected sample of 589 children (310 girls, 279 boys, mean (standard deviations, s.d.) age=9.7 (0.44) y, weight=33.6 (6.4) kg, height=1.39 (0.06) m) from Denmark. Methods Fasting blood samples were analysed for serum insulin ...
Low physical activity has an important role in the development of obesity in youth. To date, little evidence exists on the physical activity patterns of severely obese young people and no study has examined their habitual activity using objective measurements. The aims of this study were to 1) objectively determine physical ...
Objective This study aimed to describe levels of physical activity in a representative sample of preschool children and to quantify tracking of activity over 1 year. Research Methods and Procedures Physical activity (mean accelerometry counts/minute) was assessed over 3 days using the Computer Science and Applications accelerometer in 3- to 4-year-old ...
Self-report measures remain the most popular tool for measuring the habitual physical activity of large samples of children The Multimedia Activity Recall for Children and Adolescents (MARCA) is a computer delivered questionnaire which requires children to recall the previous 24-h in 5 min segments The MARCA retains the key features of ...
We examined the ability of the Computer Science Applications (CSA) accelerometer to predict energy expenditure during treadmill walking and stair stepping in nine children and adolescents with cystic fibrosis (CF) (mean age 12.1 yr, SD + 2.8) and ten healthy controls (mean age 10.8 yr. SD + 2.2). The accelerometer was attached above the hip and ...
