Energy cost and game flow of 5 exer-games in trained players.

OBJECTIVES: To determine energy expenditure and player experience in exer-games designed for novel platforms.

METHODS: Energy cost of 7 trained players was measured in 5 music-based exer-games. Participants answered a questionnaire about "game flow," experience of enjoyment, and immersion in game play.

RESULTS: Energy expenditure during game play ranged from moderate to vigorous intensity (4 - 9 MET). Participant achieved highest MET levels and game flow while playing StepMania and lowest MET levels and game flow when playing Wii Just Dance 3(®) and Kinect Dance Central™.

CONCLUSIONS: Game flow scores positively correlated with MET levels. Physiological measurement and game flow testing during game development may help to optimize exer-game player activity and experience.
