A report released this week by the Archives of Pediatrics & Adolescent Medicine maintains that kids burn calories four times as fast when engaged in an active video game than a passive one.

According to Medical News Today:

...over 83% of children in the US between the ages of 8 and 18 have video game consoles in their bedrooms. The alarming increase in obesity rates that coincides with this trend may not be a coincidence, as seated video games may contribute to time spent sedentary rather than active. 

While you might expect that the authors looked at the Nintendo Wii or perhaps multi-platform aerobic games like Dance Dance Revolution, the report focuses on the XaviX gaming system (see video), manufactured by Japan's SSD Company, Ltd. Among the XaviX's offering are simulations of bowling, fishing, tennis, and golf. The study authors comment:

In addition to the exercise gaming modalities, the XaviX system includes a gaming mat (XaviX J-Mat) that allows participants to travel the streets of Hong Kong at a walk or a run, avoiding obstacles and stamping out ninjas.

The study was performed at the University of Hong Kong's Institute of Human Performance. Kids who played games while seated burned 39% more calories per minute than when they were at rest. During an active bowling game they burned 98% more calories and during an action/running game they burned 451% more. Of this, the researchers said:

This translates into a more than four-fold increase in energy expenditure for the XaviX J-Mat game. Preventing weight gain requires an energy adjustment of approximately 150 kilocalories [calories] per day. The four-fold increase in energy expenditure when playing on the XaviX J-Mat would fill the proposed energy gap, if this game were played for 35 minutes a day...

 

Our data demonstrate that the two active gaming formats result in meaningful increases in energy expenditure compared with the seated screen environment. The next step is to test whether active gaming interventions can provide sustainable increases in childhood physical activity.

 

A friend attended the Democratic National Convention in Denver this week. Among the many items he snagged was a pamphlet from the No Child Left Inside Coalition, a group which seeks to foster environmental awareness and activity among young people.

That's all quite commendable. Less praiseworthy, however, is the fact that the group's brochure (obtained by GP) takes a cheap shot at video games in its opening paragraph:

Young people across America are spending more and more time inside - hooked up to video games, computers, and television, instead of learning, playing and exploring outside. The results are profound: increases in childhood obesity, a lack of understanding of the environment and a disconnection from the natural world.

Why some kids don't go outside or don't get enough exercise or are overweight would seem to be very complex social issues involving a myriad of factors, including available recreational opportunities, socioeconomic status, neighborhood safety, parenting, nonstop marketing of high-calorie food and drinks, etc.

Thumbs-down to No Child Left Inside for pointing the finger at video games...

It’s not always easy to predict which video games are going to upset people. 

One of the games that debuted at last week’s E3 was Sony and Titan Studios’ upcoming PSN title Fat Princess, a cartoony, capture-the-flag game in which the object is to rescue your princess from the enemy’s dungeon.  The hook is that the enemy is plumping up your princess with cake, making her more and more difficult to haul back.

It’s cute.  It’s colorful.  It’s surprisingly bloody. And, from many reports, it’s a lot of fun. But, according to Joystiq, at least two feminist bloggers have taken issue with the fat part of Fat Princess.

Shakesville’s Melissa McEwan says in an open letter to Sony:

[Fat Princess]  looks and sounds just adorable—but the only thing I can't figure out is why anyone would want to rescue a fat princess in the first place, since everyone knows that fat girls are unlovable human garbage at whom any sensible bloke would sooner hurl invective than cast a longing glance... I'm positively thrilled to see such unyielding dedication to creating a new generation of fat-hating, heteronormative assholes.

Meanwhile, Feminist Gamers’ Mighty Ponygirl offers her take:

Honestly, the “core game mechanics” are brilliant, and if I didn’t care one whit about the objectification of women or fat-bashing, I would think this was the best thing since… well, Team Fortress 2…

 

Instead of running out into the forest to find cake to fatten up the princess with, why not go out and find gold (which is a lot heavier than cake) to stuff into a treasure chest. The more gold in the chest, the heavier it would be, and the harder it would be to carry.

 

Oh, but that’s not as “cute” as cake and fat chicks. Right.

For his part, Titan Studios' art director, James Green, said in an email to Joystiq:

Does it make it better or worse that the concept artist (who designed the look, characters, everything) is a girl?
