Objective To examine the cross-sectional relationships between physical activity and dietary behaviors among 8- to 10-year-old African-American girls. Research Methods and Procedures Two hundred ten 8- to 10-year-old African-American girls from four field centers participated. Computer Science and Applications (CSA) activity monitors were worn for 3 days. CSA data were expressed ...
Background/Objectives To test the association between physical activity measured using accelerometer counts (Actigraph) and energy expenditure (EE) measured using the doubly labelled water (DLW) method in free-living children in India. The aim of this study was to explore the usefulness of Actigraphs in estimating EE. Subjects/Methods Total EE (...
Discussion of physical fitness and its relationship with physical activity is more apparent in adults than in children and adolescents (Malina 1996). A large portion of the variability in physical fitness is not accounted by physical activity (Malina, 2001). This suggests that, among pediatric subjects, other factors are involved and need to ...
Background It is unclear how moderate and vigorous intensities of physical activity (PA) are associated with cardiovascular fitness (CVF) and percentage of body fat (%BF) in adolescents. Objective We tested the hypothesis that vigorous PA, to a greater degree than moderate PA, would be associated with better CVF and lower %...
Background Strategies for the prevention and treatment of childhood obesity require a better understanding of the relation between the pattern of free-living physical activity and total energy expenditure (TEE). Objective We assessed the relations between TEE and physical activity level (PAL) during engagement in different intensities of physical activity. Design ...
Researchers support the relationship of task orientation with exerted effort persistence and self-reported physical activity but there is little evidence on the relation of goal perspectives with objective measures of physical activity The purpose of this study was to examine behavioral correlates of goal orientations using an objective measure of ...
Purpose To evaluate the reliability and validity of the CSA (model 7164) accelerometer (MTI) in a wide walking-running speed range in laboratory and field. Method Twelve male subjects performed three treadmill walking/running sessions and one field trial with the same continuous protocol involving progressively increasing velocities at 5 min per interval ...
Objective The objective of this study was to determine whether a generalizable best-practice individualized behavioral intervention reduced BMI z score relative to standard dietetic care among overweight children. Methods The design consisted of an assessor-blinded, randomized, controlled trial involving 134 overweight children (59 boys, 75 girls; BMI > or = 98th centile relative to United ...
Purpose To describe adherence to a home-based walking intervention among breast cancer survivors using three methods and to evaluate predictors of intervention adherence. Methods In this ongoing intervention, participants received an in person counseling session and up to five telephone counseling calls The intervention focused on goal settling, reinforcement, social ...
Purpose The aim of this study was to assess the predictive validity of three accelerometer prediction equations (Freedson et aL, 1997; Trost et aL, 1998; Puyau et al., 2002) for energy expenditure (EE) during overland walking and running in children and adolescents. Methods 45 healthy children and adolescents aged 10-18 completed the following protocol, ...
