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 %...
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 ...
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 ...
Purpose To describe the type and intensity of PA which contribute to higher PALs among middle-aged women. Methods Women consumed DLW on day 0 and returned 1, 7, and 14 days later to provide urine samples for DLW determination of total energy expenditure (TEE).. Women wore the CSA accelerometer (AM7164) and completed seven 24-hour ...
Objective The aim of this study was to evaluate the relationship between objectively measured physical activity (ACT), particularly intensity of physical activity (iACT), and body fat percentage (BF%) in 278 middle-aged women. Secondary purposes were to ascertain the association between physical activity duration (dACT) and BF% and the content to which ...
Objective This study aimed to describe levels of physical activity in a representative sample of preschool children and to quantify tracking of activity over 1 year. Research Methods and Procedures Physical activity (mean accelerometry counts/minute) was assessed over 3 days using the Computer Science and Applications accelerometer in 3- to 4-year-old ...
Purpose The main objective of the present study was to determine the extent to which objectively measured aerobic fitness (VO2mSX) was predictive of bone mineral density (BMD) in 237 middle-aged women. Additional aims were to determine the extent to which differences 3n age, body weight, and objectively measured physical activity ...
Purpose The purpose of this study was to determine the extent measured changes in total dietary fiber (FIB) per 1000 kcal were predictive of changes in body fat percentage (BF%) in 228 middle-aged women during a 20-month prospective study. Other objectives were to ascertain the extent differences in age, and various baseline ...
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 ...
