Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The primary purpose of this study is to test whether rewarding physical activity with a motivational website will increase physical activity levels in middle school-aged children over six months. As a secondary outcome, the study also tests the intervention's impact on biological measures of inflammation and metabolic function in a sub-set of study participants who agree to provide blood samples.
