OBJECTIVE.We examined the effect of activity-enhancing screen devices on children’s energy expenditure compared with performing the same activities while seated. Our hypothesis was that energy expenditure would be significantly greater when children played activity-promoting video games, compared with sedentary video games. METHODS. Energy expenditure was measured for 25 children aged 8 to 12 years, 15 of whom were lean, while they were watching television seated, playing a traditional video game seated, watching television while walking on a treadmill at 1.5 miles per hour, and playing activity-promoting video games. RESULTS. Watching television and playing video games while seated increased energy expenditure by 20 13% and 22 12% above resting values, respectively. When subjects were walking on the treadmill and watching television, energy expenditure increased by 138 40% over resting values. For the activity-promoting video games, energy expenditure increased by 108 40% with the EyeToy (Sony Computer Entertainment) and by 172 68% with Dance Dance Revolution Ultramix 2 (Konami Digital Entertainment). CONCLUSIONS. Energy expenditure more than doubles when sedentary screen time is converted to active screen time. Such interventions might be considered for obesity prevention and treatment.
