Screen time for both TV and video games now averages eight hours a day among children. (Who are these kids? Don’t they have chores and homework?) If playing video games makes kids less active and contributes to obesity, why not create more video games that require activity? That’s the question prompted by a Mayo Clinic research study published in the current issue of the medical journal, Pediatrics. The study is the first to scientifically measure the energy spent playing video games. While the study’s scope is small (only 25 children), it was reportedly conducted with great accuracy.

Fifteen children were of normal weight for their height and frame while 10 were mildly obese. Both groups were tested while sitting and watching television, playing a traditional video game, playing two types of activity-required video games and watching television while walking on a treadmill. The results showed that sitting while watching television and playing traditional video games expended the same amount of energy. When participants played the first activity-oriented video game, one that uses a camera to virtually “place” them in the game where they catch balls and other objects, their energy expenditure tripled. The result was the same for the lean and mildly obese children.

Walking on a treadmill while watching TV tripled the energy expenditure for the lean group, but showed a nearly fivefold increase for the mildly obese group. While using a dance video game, both groups burned the most calories, but it was considerably more for the obese group — just over six times more than sitting still. The Mayo researchers suggest requiring activity in more video and computer games is one potential approach for reversing the obesity trend.
