Staiano, A.E., Abraham, A.A., & Calvert, S.L., Motivating Effects of Cooperative Exergame Play for Overweight and Obese Adolescents, explored factors that motivated overweight and obese African-American high school students to play Wii Active games in a school-based lunchtime and after-school program. The study found greater and more sustained energy expenditure over time in a cooperative play condition, compared to a competitive play condition, and found that players’ various intrinsic motivations to play also influenced their level of energy expenditure. The study points to the advantages of cooperative game play for this population and it demonstrates that games can be especially effective when they enable players to do what is personally important, relevant, and intrinsically motivating to them.
