What is "exergaming"

n. The playing of video games that also provide the player with physical exercise.

Fitness game, exergaming or exer-gaming (a portmanteau of " exercise" and "gaming"), or gamercising is a term used for video games that are also a form of exercise. Exergaming relies on technology that tracks body movement or reaction. The genre has been credited with upending the stereotype of gaming as a sedentary activity, and promoting an active lifestyle. Research indicates that exergames can produce real improvements in fitness. Exergames are seen as evolving from technology changes aimed at making video games more fun.
