Active Video Games and Energy Expenditure in Overweight Children.

The prevalence of overweight in children has increased significantly in recent years. Frequent television viewing and the playing of video games have often been linked to the high prevalence of overweight. The purpose of this study was to determine if overweight children, given access to active video games, will play them at an intensity that will significantly increase energy expenditure. Twenty-three children, classified as "at risk for overweight" or "overweight," participated in this study. After a 10-minute baseline period in which the children watched a cartoon, the participants played the Jackie Chan Fitness Studio® (Xavix, Hong Kong) games for 30 minutes while rotating through the games as desired and resting whenever needed. Energy expenditure significantly increased from a mean at baseline of 1.15 ± 0.32 kcal/min to 4.08±1.18 kcal/min during the 30-minutes that the participants were given access to the games ( <.001). The total energy expenditure during the 30-minute time frame was 122.30 ± 35.40 kcal. The energy expenditure varied between individuals, with a low value of 75.00 kcal to a high of 205.86 kcal. Although a modest level of energy expenditure, this level of exertion could contribute to an overall weight control program in children.
