Ever wonder if video games like Wii boxing actually have some health benefits?  A recent study published in the journal Pediatrics suggests that playing active video games may be similar to moderate-intensity walking.  Dr. Graf and colleagues examined energy expenditure in 23 children (14 boys and 9 girls) between the ages of 10 to 13 years.  Kids watched 20-minutes of cartoons while lying down before playing Dance Dance Revolution (DDR) (on visit 1) and Wii bowling and boxing games (on visit 2) for 30 minutes followed by 10-15 minutes of resting.  In addition, after the resting period during visit 2, children walked on a treadmill while watching cartoons for 18 minutes.  The researchers measured energy expenditure, blood pressure, and arterial elasticity.  Findings showed that energy expenditure, heart rate, and ventilatory responses were similar to or greater when children engaged in Wii boxing or DDR compared to moderate-intensity walking (4.2-5.7 km/hour).  Energy expenditure three times greater during these activities than during resting.  Interestingly, boys expended more energy during DDR and Wii bowling than girls (no differences were found during Wii boxing, rest, or walking), which the authors speculate may reflect differences in motivation or exercise economy.

Although video games should never replace real sports, occasionally playing these active video games can be good for you.  However, keep in mind that not all active video games are the same: energy expenditure during Wii boxing was 50% greater than during Wii bowling.

Here's an inexpensive way to get the Wii. The Wii Mini Console System comes with the Mario Kart game and is only about $125! Compare that to the non-mini Wii and you'll save several hundreds of dollars. The difference? The mini Wii does not connect to the internet or have a USB or SD slot for viewing your pictures. It will play any Wii game, and you can hook up the basic Wii remote, the nunchuck, or even the steering wheel. If you want to use the balance board package (below), you will need to have a console. 

The Wii Fit software and Balance Board bundle sells for only about $120, which can be used with any existing Wii system (except the Wii U). It includes the game disk with tons of workout routines, including both yoga and strength training. You can improve your balance, target certain body areas like your abs or glutes, and get a range of fun workouts that will increase your heart rate and help you and your kid stay healthy and burn calories. The balance board is wireless and runs on two AA batteries.

You don't need to use the Wii in order to get a good workout. If you've got a larger budget, you should also check out the XBox Kinect and Playstation options.
