This
project will evaluate the utility of a commercially available portable
device (SenseWear Pro
Armband) in the assessment
of energy expenditure during physical activity in severely overweight
children in the laboratory
and at home. This work will provide important preliminary data for
an
application designed to
evaluate the impact of an intensive physical activity intervention on overall
energy expenditure in severely
overweight children. Specific aims for the investigation will be
to:
1. Examine the energy
expenditure of severely overweight children in the laboratory during an
acute
physical activity session
using a dance game and an indoor walking video;
2. Examine the accuracy
of the SenseWear Pro Armband in the assessment of energy expenditure
in severely overweight children
during a laboratory physical activity session using a dance game
and an indoor walking video
in comparison to indirect calorimetry; and
3. Examine the compliance
of overweight children with utilizing the SenseWear Pro Armband at
home performing either the
dance game or indoor walking video during a 2-week home-based
program. |
