A Comparison Of The Actigraph 7164 And The Actigraph Gt1m During Self-Paced Locomotion, Sarah Kozey, John Staudenmayer, Richard Troiano, Patty Freedson
Patty S. Freedson
Purpose—This study compared the ActiGraph accelerometer model 7164 (AM1) to the ActiGraph GT1M (AM2) during self-paced locomotion. Methods—Participants n = 116, 18–73y, mean BMI = 26.1) walked at self-selected slow, medium, and fast speeds around an indoor circular hallway (0.47km). Both activity monitors were attached to a belt secured to the hip and simultaneously collected data in 60 second epochs. To compare differences between monitors, the average difference (bias) in count output and steps output were computed at each speed. Time spent in different activity intensities (light, moderate, vigorous) based on the Freedson et al. cut-points was compared for each …
"A"-Kids: Activity Kcal Intervention Daily Study. Effects Of 100-Kcal Daily Energy Expenditure On Total Moderate-To-Vigorous Physical Activity In 3rd Grade Children, Cheryl A. Howe
Open Access Dissertations
A selection of common children’s games were measured in a laboratory-based study to be enjoyable and to elicit sufficient physical activity energy expenditure (PAEE) in 3rd grade children to combat the purported chronic energy surplus of childhood obesity (~100 kcal.day-1). PAEE during the games was similar for boys and girls, yet overweight children expended greater PAEE relative to body weight than healthy weight children. During a subsequent simulated recess program, the enjoyment declined over the 10-session program with no significant decline in PAEE. Using the enjoyable games of known energy cost in a structured recess program for 9 weeks successfully …
