Wii Fit Moves Women into Moderate Intensity Physical Activity - MPA (study)

In this recent Wii Fit study, researchers investigated the energy expenditure of young females across different game levels.  Of course it makes sense that different levels will require different movements or more intense or more frequent movements, but until now there has been little in the area of level of game play and energy demands.

Population: Adults (young female)
Number of Participants: n=8
ExerGame Software Title: Wii Fit
Games: Stepping and Hula
Levels: Beginner and Intermediate
Results: Highest energy expenditure and % of VO2 max at intermediate hula - but still in the moderate level of physical activity intensity MPA (~4.5 MET).

Points 2 Ponder (P2P)
  • What does the hardest level look like in terms of VO2, METS, RPE, RER?
  • Did the participants enjoy the games?
  • Was their any correlation between enjoyment and perceived exertion?
