According to Wikipedia - Exergaming (a combination of "exercise" and "gaming") is a term used for video games that also provide exercise. Exergames have one element of exercise and one element of gaming.
 
Wii Fit, while all the rage with consumers these days, is just one many exergames. One of the most popular has been Dance, Dance, Revolution (DDR), a dancing game following lighted squares on the floor. One of the downfalls of video games (and why I won't let our kids play them) is the sedentary aspect of them. It (too much inactive time in front of video games, computer, and TV) is one of the contributing factors of the ongoing childhood obesity problem. Exergaming takes the individual off the sofa and gets them to move.
 
What's the real health and fitness benefit from using these games/programs? Well, the benefits of physical activity include cardio-vascular health, better weight management, reduction of anxiety and stress, improved sensory-motor learning, and improved cognitive alertness and performance, and, this is physical activity. There is research that shows improvements in all of these areas with daily use of various exergames. There is even research that shows that "Wii-habilitation 'could prevent elderly from falls". Will this replace the need to do other types of exercise? Will it replace the need for health clubs?
 
I'm afraid the answer is a resounding, "No". The catch to the whole thing is that maximal health and fitness requires ever-progressing workloads for continued adaptation. (If you don't do more, you don't get more.) The programs don't create a personalized workout based on your individual special needs (i.e. high blood pressure or adapting for injuries). No one is checking your form or keeping you safe.
 
What exergaming does do well that it needs to be commended for is getting the sedentary individual up and moving. It also gives a physically active option for those that like video games. Anything that gets you to move more will have some health and fitness benefits. Let's face it. People will use it because it's fun and entertaining.
 
I guess the ultimate answer is that we will allow our sons to save their money and buy a Wii even though I'm dead set against video games. (Of course that comes with a 20 minute time limit. I'd still rather have them go outside and play.)
