Exergames, games that make the user get up and move, are hardly a new phenomenon.Studies suggest interactive exergames (like Wii Fit or Just Dance, for example) can have a positive health impact, burning calories and getting sedentary gamers more active than traditional games. In terms of calories burned, playing active video games is comparable to mild-to-moderate physical activity. Exergames get kids’ muscles working and their heart rate up, which is definitely a good thing. New exergames are being developed monthly in the pursuit to encourage users to voluntarily choose to be active, while also doing something engaging and fun. Dr. Elizabeth Murray discusses exergaming and whether it's a viable alternative to other exercise routines.
