Playing video games to keep fit?

Without the glitzthe music, the instructor, the beatexercise can be really, really boring. Its no wonder, then, that video games like Nintendos Wii Fit and Konamis Dance Dance Revolution are being marketed as alternatives not just to couch-potato gaming, but to traditional exercise itself.

Last year, Nicole Nixon was one of a handful of kinesiology students who explored the potential health benefits of Nintendos Wii gaming console and its motion-control capabilities. Now shes expanding that research to include the popular Wii Fit game and also testing the health benefits of a new prototype game called MOVES that has been produced by masters students at Carleton University.

I honestly didnt expect to come back to gaming in my studies, says Ms. Nixon. But my thesis supervisor sent me an e-mail about the MOVES project and it caught my interest. I think its the fact that we see so many people in our society who are inactive, and were always looking for entertaining alternatives to exercise. And I want to make sure that they actually work.

Youve probably already heard about Wii Fit. Released last spring, it was even harder to find on store shelves than the Wii system itself this past holiday. Using a weight-sensitive Balance Board, Wii Fit features a number of exercise games and activities and maps the users progress over time. To date, its sold over 14 million copies worldwide.

MOVES is a slightly different beast. Its an active game that uses accelerometer system to detect full body poses, explains Hannah Johnston, who worked on the software as part of her masters program in information technology at Carleton. We enacted multiple sensors to enforce more rigorous movement, focusing on the lower body as well. We hope that it makes for a more active game.

Obviously, given that MOVES is a prototype, its production values arent quite at the same level as Nintendos creation. But its still got the core elements of an active game: visual prompts that direct the user what dance moves to attempt, a pumping soundtrack and stats to indicate how many of the moves youve successfully completed.

By hooking test participants up to a heart monitor that wirelessly downloads results to a computer database, Ms. Nixon is comparing how well MOVES and Wii Fit provide a cardiovascular workout. Participants spend 30 minutes with each activity, as well as 30 minutes playing an old-fashioned Super Nintendo system to show the difference versus traditional gaming. She also is asking participants to record how much they enjoy each activity and also their level of perceived exertionhow much they think theyre exercising.

Sara Shanahan, a fourth-year year psychology student, is one of the studys participants. Its pretty cool, she says. I own DDR (Dance Dance Revolution), and while this is similar, it incorporates the upper body into it more. Its pretty tiring.

Manu Saraswat, also in kinesiology, is a little more uncertain about the product but thinks that the concept has potential. Its a bit choppy and it doesnt dance so well yet, but the technology holds promise for actually teaching someone how to dance.

Ms. Nixon will be compiling her results for her honours thesis, due for completion next month.
