Purpose To evaluate the differences in physical fitness and physical activity between 9- and 15-year old girls and boys in Oslo, and to evaluate the relationship of those variables with obesity. Methods Four hundred and ten 9-year olds and 347 15-year olds participated in a cross-sectional study as a part of ...
Objective To study the physical activity patterns and daily estimates of energy expenditure (EE) of rural adolescent Senegalese girls. Design Physical activity was monitored using a portable accelerometer during four consecutive days and within the same time, by direct observation during two consecutive days. Adolescent girls were followed during the ...
Purpose The purpose of this study was to assess physical activity levels and patterns from children participating in the European Youth Heart Study (EYHS) Very limited physical activity data exist that have been collected from representative samples of children and even fewer data collected where physical activity has been measured ...
The prevalence of obesity is high in American Indian children (AI) and adolescents, and there is a need for valid methods for estimating energy intake and expenditure that can be applied in large-scale epidemiological studies and prevention programs. Thus, we compared two physical activity (PA) assessment methods, accelerometry and PA ...
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 ...
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 ...
Background The influence of physical activity on body weight in children and adolescents is controversial. Objective The objective was to test the hypothesis that the intensity and duration of physical activity differ between obese and normal-weight adolescents, with no difference in estimated energy expenditure. Design We compared physical activity in 18 (8 ...
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 ...
Background Questionnaires are feasible instruments to assess physical activity (PA) in large samples. The aim of the current study was to evaluate the reliability and validity of the PAQ-A questionnaire in Spanish adolescents using the measurement of PA by accelerometer as criterion. Methods In a sample of 82 adolescents, aged 12 to 17 ...
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 ...
