The most interesting result of the study? The dancing game actually expended more energy than walking on the treadmill. Hit the jump for exactly what those results were.

While watching TV and playing traditional video games, both groups of kids expended the same about of energy. Using the camera game, they used three times the amount of energy. Walking on the treadmill, the normal weight kids used three times the energy, while the mildly obese kids used five times the energy. Both groups used the most energy in the dancing game, with the mildly obese group burning six times the amount of energy than sitting still.

I think this study would have been made all the more interesting if they'd used more current games, like anything for the Wii, Wii Fit in particular, but the results are kinda neat, nonetheless.

Mellone Cutts is the head of PE at Lea Manor High School which took part in the trials.

"There is a number of students who we don't reach with competitive sports," she said.

"With more and more children becoming obese, one way we can help is by increasing participation in sport and this does that."

And who says video games have no redeeming value?

We were interested in measuring the levels of exertion from an exercise physiology point of view and compared the average heart rate that each subject was exercising at to the American College of Sports Medicine's (ACSM) recommended exercise heart rate range. Our findings reveal that playing these video games can provide an effective workout.

If there's one problem with "exergame" popularity and titles like Kinetic and DDR, it's that gamers need to make sure the trend doesn't get out of hand.

We're only saying this once, and let's keep this amongst ourselves: we can't let the jocks take over.

Some gyms are integrating dedicated exergaming machines into their circuit of traditional exercise machinery, with some business springing up around the concept of family-based exercise complete with Dance Dance Revolution arcade set ups.

Fitness clubs like Bally and other staid institutions, such as the YMCA, look to experiment further with exergaming in the future, hopefully helping reduce our ballooning fat kid problem.

Thanks for the tip, Melissa! Michael McWhertor

We first wrote about Mickey DeLorenzo back in early December when he set out to lose weight by playing Wii Sports.

hey_suburbia at WiiNintendo.net plans to spend 30 minutes a day playing Wii sports, from December 3rd to January 15th, in order to chart the effect it has on his body, tracking his pain, weight, Wii Fitness Age, etc.

I was talking to the Rocky's fitness writer about his story recently and she pointed out that he would have had to burn an extra 750 calories a day to lose that much weight that quickly without dieting. Looking through his calorie breakdown for each of the mini-games, it's easy to see that simply wasn't possible, typically.

A poster on the site points out the same thing:

its takes 3500 kcal to burn 1 pound of fat. You lost 9 lbs. If your caloric energy balance remained unchanged this means you would have to burn 750 calories a day.

I'm glad you lost weight and I'm glad you are motivating people to become more active but its unlikely that your results are typical. cool site though. I dugg it.

Couldn't have said it better myself. Brian Crecente

Ben Kuchera has an excellent article posted over at Ars Technica, in which he tackles a subject that has been on everyone's mind since the release of the Wii, that being gaming and fitness. Unlike the Wii Sports Experiment, Kuchera avoids the Wii itself, opting for more fitness oriented games like Dance Dance Revolution, Yourself Fitness, and to a lesser extent, Eyetoy Kinetic. He adjusted his diet and worked out using the games for 45 minutes a day, 4 days a week, for two months. I don't want to spoil the result, but let's just say he did not gain weight.

I'd suspect the adjusted diet has a great deal more to do with the weight loss than anything. You'd be amazed at home many calories some of things we eat and drink. I myself lost nearly 50 pounds earlier this year simply by taking a walk every day and switching to diet soda. Of course I gained half of it back after I started writing for Kotaku, but the extra weight just makes e that much more cuddly. Michael Fahey

It'll be interesting to see how this turns out, though as some commentors on his page have already pointed out it really isn't all that scientific without taking into account the food you eat and other activities. I'm just overjoyed that I didn't end up having to do it. Hooray for sloth! Michael Fahey

Wii Sports Experiment [WiiNintendo.net, via Hot Shot Gamer]

I woke up Saturday morning after a Friday filled with at least 10 hours of playing Dragon Ball Z and Raving Rabbids on my Nintendo Wii, and my shoulders hurt like hell. I was sure I had slept wrong or something, since the pain felt similar to a stiff neck. It wasn't until later when I pulled out the Wiimote for some more crazy-haired fighting action that I realized where the pain was coming from. A day of holding my arms out and swinging them around had taken its toll on my poor, neglected muscles. Apparently I am not alone. Wall Street Journal, world renowned for its video game coverage, posted an article on Saturday related to the Wii-pain phenomenon, in which Nintendo's Perrin Kaplan addresses the issue.

"It was not meant to be a Jenny Craig supplement," she says. "If people are finding themselves sore, they may need to exercise more."

UK Company Gymkids unleashes a new weapon in the war against a global epidemic - fat kids. The company is releasing the Step2Play, a stair stepper device that hooks up to any Playstation 1 or 2 system, allowing your child to play only as long as they continue walking, an idea I believe they stole from Dante's Inferno. They stop walking, the game stops playing. It features an adjustable exercise rate sensor, allowing you to set the machine to a slow pace, for when you are feeling merciful, or a quick trot, for when you are overcome by feelings of parental failing and want to take it out on your overweight children.

The fact that this would ever be considered necessary is depressing. I was a video game junkie as a child and I still managed to hop outside long enough to get hit with a few dodge balls and burst into tears. Children need to get hit with dodge balls. It is an integral part of growing up. Someone should create a product that does that instead.

The Step2Play is scheduled to begin torturing youth in time for Christmas. It's an excellent alternative to actually spending time outside with your child. Michael Fahey

This meat puppet I walk around in? Not only do I want a refund, but I can't believe the amount of upkeep it requires to work properly, including exercise... something I hate doing because it's just plain hard. As far as I'm concerned, the sooner science can extract my brain with a mashed-potato scoop and slap it into a super-sexy, non-degrading cyborg body with a prehensile penis, retractable machine gun turrets growing out of triple-D breasts and a Wii disc slot directly interfacing with my brain, the better.

But that's a few years off. In the meantime, Tim Tucker has tried to make physical fitness more exciting to flabby Jabbas like me by melding Tetris with weight lifting. Apparently, you sit in a chair and use a series of pulleys connected to weights to shift the Tetris pieces from left to right and rotate them.

It is, of course, an absurd idea, but no more absurd than the bloated, farting sack of gelatin with which my soul somehow became infused. Worth a shot until those cyborgs come around. Florian Eckhardt

Game Set Watch has a great post up summarizing the personal connections a lot of people feel towards Maya, the peppy virtual fitness instructor from Yourself! Fitness. A lot of people tend to think of Maya as a real person. Although I would normally consider such people out of their fargin' gourds, I actually understand this, because Yourself! Fitness helped me get in shape.

Last year, I spent an entire winter floating like some alcoholic fetus in a huge vat of Guinness, nourishing myself and growing larger and larger through the absorption of the dark, creamy embryonic fluid in which I subaqueously dwelled. When spring arrived and I finally burst through the keg's placenta, it was time to get in shape.

So I spent thirty minutes every day gaily prancing about my kitchen as Yourself! Fitness virtual trainer Maya shouted peppy slogans at me. "How did you feel about that last set?" she'd ask me every once and a while. "My heart just exploded," I'd respond. But Maya could always put the best face on anything: "Good! That means you're challenging yourself!"

I owe my svelte, sexy frame to Maya. And even though she's just a polygon, I have a great deal of fondness for her. In making me suffer and work for my goals, I actually do find myself sort of thinking of her as a real person from time to time. A real person whose sublime, spandex-sprayed ass I'd gnaw off my arm to spank just once FLORIAN ECKHARDT

Yourself! Fitness - A Diary To Greatness

Jackie Chan is swinging his hips at me again. I'm trying to keep pace, but finding it hard. We've only been at it five minutes, and I'm already starting to feel the burn. Jackie makes big gestures with his hands. I wonder if I should do the same. Ah, what the hell.

Somewhere children giggle.

I'm a sucker for testing crap. When I saw the XaviX display in Yodobashi Camera, I had to try it out. While kid and wife wandered off to test fat scanning scales, I decided to burn off the curry rice I had fer lunch. And Jackie Chan was going to whip me into shape or something like that.

After I entered my age (27) and my weight (59 kgs) and my sex (male), Jackie appeared. The Yodobashi theme song was blasting through the store over and over again, so I couldn't really hear what kinda music was propelling exercise game. (I wonder if that stupid thing song drives the Yodobashi staff batty or if they've become numb? Perhaps they have special earplugs...)

With that retarded theme song blaring and children giggling and pointing, testing conditions weren't exactly prime. I wanted to tell them to stuff. I'm working dammit! I couldn't even figure out if I was supposed to copy Jackie or if I should've followed these DDR style patterns that appeared on the screen. Or maybe I should've done both. Copying Jackie's hip sways and arm gestures—now, those I should've skipped.

Jackie Wants to Pump You Up

Jackie Chan wants to pump you up. The Hong Kong star has been roped in as the spokesman for the XaviX Port, which is an external exercise device. This isn t the first marriage of gaming and exercise, but it does have to be one of the first game consoles designed strictly for exercise.

The unit hooks up to your TV just like your PS2 or X-Box. Exercise is done by inserting Xavi exercise cartridges and using special peripherals. The company is planning an aerobics game, along with boxing, tennis, and bowling. For the boxing game, the player uses special boxing gloves. Their movements are shown on the screen in real time. For the aerobics game, players use a DDR style mat (just like in Konami s exercise game). Tennis uses small rackets, while the bowling game uses a large green bowling ball that is wired to your game console. Just waiting to blog a story about some dude that accidently chucks a green bowling ball into his TV.

The company site has a couple of ads and press releases with product pics.
