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
To describe the levels of physical activity and energy intake in a sample of Bolivian Adolescents.
Setting
La Paz, September-October 2004. Methodology: 45 secondary school students (19 males; 26 females; mean age 15.6 SD 1.25) wear accelerometers (Actigraph-7164; http://www.theactigraph.com) during three days. Anthropometric measurements were registered. A semi-quantitative food frequency-questionnaire was used ...
This study compared the determinants of physical activity in active and low-active African-American sixth grade students (N = 108, 57 F, 51 M). Objective assessments of physical activity over a seven-day period were obtained using the CSA 7164 accelerometer. Students were classified as active if they exhibited three or more 20-minute bouts of moderate to ...
Objective
To evaluate the theory of reasoned action (TRA) and planned behavior (TPB) In predicting moderate-to-vigorous physical activity (MVPA) in sixth-grade youth.
Methods
One hundred ninety-eight students completed a questionnaire measuring attitudes, subjective norms, perceived behavioral control, and intentions to be active. MVPA was measured using the CSA 7,164 accelerometer.
Results
...
Purpose
To derive a regression equation that estimates metabolic equivalent (MET) from accelerometer counts, and to define thresholds of accelerometer counts that can be used to delineate sedentary, light, moderate, and vigorous activity in adolescent girls.
Methods
Seventy-four healthy 8th grade girls, age 13-14 yr, were recruited from urban areas ...
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% ...
Purpose To use objective monitoring of physical activity to determine the percentages of children and youth in a population that met physical activity guidelines.
Methods A total of 375 students in grades 1–12 wore an accelerometer (CSA 7164) for seven consecutive days. Bouts of continuous activity and accumulation of minutes spent in physical ...
Introduction
The aim of this study was to evaluate the agreement between the ActiGraph accelerometer and the Bouchard diary to estimate energy expenditure (EE) in a Spanish adolescent population.
Methods
Sixty-one Spanish adolescents, aged 12-16 years, were recruited for this study. The Bouchard diary and the ActiGraph were administered for 3 ...
Objective
Juvenile primary fibromyalgia syndrome (JPFS) is a chronic pain condition associated with significant impairment in physical functioning, but no studies have used newer technologies such as actigraphy to document objective physical activity levels in JPFS.
Methods
This is the first study to objectively describe physical activity in JPFS patients ...
Purpose
To compare the test-retest reliability, convergent validity, and overall feasibility/usability of activity-based (AB) and time-based (TB) approaches for obtaining self-reported moderate-to-vigorous physical activity (MVPA) from adolescents.
Methods
Adolescents (206 females and 114 males) completed two 3-d physical activity recalls using the AB and TB surveys, which contained identical lists of ...
