Six months
Secondary Outcomes (1)
Metabolic and inflammatory biomarkers
Six months
Study Arms (2)
Website intervention
EXPERIMENTALParticipants randomly assigned to the Website Intervention arm receive access to the motivational rewards website. The website displays the individual's physical activity data and allocates reward points based on the amount and intensity of physical activity. The website also allows reward points to be redeemed for various rewards such as gift cards to retail outlets, donations to charities, small tangible goods, and customization of participants' cartoon-like avatars on the website.
Control
NO INTERVENTIONParticipants in the control group will not have access to the motivational website. No other product or intervention will be introduced to the control group.
Interventions
The Zamzee intervention is designed to motivate middle school-aged children to increase their rates of moderate to vigorous physical activity (MVPA) by providing rewards based on amount and duration of physical activity. Rewards include gift cards to retail stores, donations to charity, small tangible goods, and customization of their cartoon-like avatars on the website.
