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 ...
To evaluate the theory of reasoned action (TRA) and planned behavior (TPB) In predicting moderate-to-vigorous physical activity (MVPA) in sixth-grade youth.
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.
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.
Seventy-four healthy 8th grade girls, age 13-14 yr, were recruited from urban areas ...
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.
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 ...
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.
Sixty-one Spanish adolescents, aged 12-16 years, were recruited for this study. The Bouchard diary and the ActiGraph were administered for 3 ...
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.
This is the first study to objectively describe physical activity in JPFS patients ...
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.
Adolescents (206 females and 114 males) completed two 3-d physical activity recalls using the AB and TB surveys, which contained identical lists of ...
Background and Objectives
To review the clinimetric quality of motion sensors used to assess physical activity in healthy children and adolescents (2-18 years).
A systematic literature search was performed in PubMed, Embase, and SpycINFO. The clinimetric quality of two pedometers (Digi-Walker3 Pedoboy), four one-dimensional accelerometers (LSI, Caltrac, Actiwatch, CSA/...
No previous studies about the Thai adolescent’s physical activity patterns using accelerometers have been published, aiming at planning and implementing effective health intervention programs for weight management in Thailand.
To describe differences in physical activity patterns, measured by accelerometers across weekdays and weekend days, in overweight secondary-school ...
