Study Details

Study Description

Brief Summary

This pilot study seeks to compare the change in energy expenditure and fitness levels of patients seen in the Children's Hospital Preventive Cardiology program receiving standard of care provider exercise counseling to similar patients receiving Frequency, Intensity, Time, Type (FITT) exercise prescription and counseling combined with BodyMedia supported by an online interactive tool.

The investigators primary hypothesis is that this interactive technology coupled with support from a exercise specialist will increase the energy expenditure of the investigators patients over standard of care provider counseling.

The investigators Secondary hypotheses include greater improvement in measured physical fitness Peak oxygen consumption (VO2max), oxygen consumption (VO2) at anaerobic threshold (AT) and ventilation/carbon dioxide (VE/VCO2) slope, lipid profiles, blood pressure, arterial stiffness, body mass index (BMI), BMI percentile, and self-efficacy in the intervention group compared to control.

Arms and Interventions

Arm Intervention/Treatment
No Intervention: Standard of Care

standard of care (office provider exercise counseling)

Experimental: Intervention

The intervention group received a personalized exercise prescription (using the FITT principles) and wore an accelerometer up to 7days/week (most waking hours) and logged their activity by regularly (3 times a week) uploading the device for a period of 3 months, use of the internet was supervised by a parent or guardian. Their activity was monitored via the online BodyMedia site on a regular basis by study personnel and feedback was provided at least once a week through email and/or phone calls

Device: BodyMedia
Accelerometer

Outcome Measures

    Total time (minutes) in Physical Activity in one week

Secondary Outcome Measures

  1. Body Mass Index [Baseline, 3 months]

    Secondary hypotheses include greater improvement in body mass index (BMI) reported below.
