Background
Atherosclerosis develops from early childhood; physical activity could positively affect this process. This study’s aim was to assess the associations of objectively measured physical activity with clustering of cardiovascular disease risk factors in children and derive guidelines on the basis of this analysis.
Methods
We did a cross-sectional ...
Four Computer Science and Applications (CSA, Model 7164) accelerometers were validated against speed and heart rate in a field trial, consisting of two walking and two preset running speeds, and 3 min of running at freely chosen speeds. Fifteen children (9–11 years) were recruited from a suburban school in Denmark. Mean CSA output ...
Research analyzing the influence of physical activity (PA) on skeletal have been focused on bone material properties such as bone mass and few studies were conducted on bone morphologic properties.
Purpose
To analyze the influence of PA on morphologic variation of proximal femur in pre-pubertal boys, probably the most active ...
Children's independent mobility has fallen in recent years and may in part explain reported declines in physical activity in young people. This cross-sectional study investigated whether independent mobility in boys and girls was related to objectively measured physical activity.
Methods Thirteen hundred and seven 10-11 year old boys and girls ...
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)> ...
Purpose
To test for relationships between objectively measured habitual physical activity and fundamental movement skills in a relatively large and representative sample of preschool children.
Methods
Physical activity was measured over 6 d using the Computer Science and Applications (CSA) accelerometer in 394 boys and girls (mean age 4.2, SD 0.5 yr). Children were ...
Purpose Bone adapts to changing mechanical loads by altering the structure appropriately. These adaptations should be evident in the bone cross-sectional area (CSA) and section modulus (Z), indices of axial and bending strength, respectively. In this cross-sectional study, we investigated associations between physical activity, CSA, and Z in 467 young children (...
Purpose
To evaluate the differences between Caucasians and non-Caucasians with regard to cardiorespiratory fitness, physical activity and obesity measures.
Methods
Four hundred and ten 9-year old children and 347 15-year old youths participated in a cross-sectional study as a part of the European Youth Heart Study. The non-Caucasians constituted 17% of the ...
Objective
The purpose of this study was to identify the psychosocial and environmental correlates of objectively measured physical activity behavior in a diverse sample of sixth-grade students.
Design
Cross-sectional.
Participants and Settings
One hundred ninety-eight sixth-grade students from 4 public middle schools in Columbia, South Carolina. The study group was 52.0% female, 55.1% ...
Participants, Methods, and Results
We monitored physical activity during waking hours for seven days using accelerometers (Manufacturing Technology, Fort Walton Beach, FL) in 215 children (120 boys and 95 girls aged 7.0-10.5 (mean 9.0) years) from three schools with different sporting facilities and opportunity for physical education in the curriculum. School 1, a private preparatory ...
