Video games that require player(s) to be physically active are growing in popularity. The animated virtual-reality appeal of these games may be a critical tool in increasing the amount of time people spend in daily moderate to vigorous physical activity. With our nation in the midst of an obesity epidemic (USDHHS, 2001), it is important to examine new and innovative opportunities to engage in physical activity. The primary purpose of this study was to examine enjoyment levels and changes in body composition in college students after 8 weeks of playing an interactive dancing arcade game. Twenty-six participants (14 female, 12 male) aged 18-29 reported to the lab to play Dance Dance Revolution (a popular interactive dancing arcade game) 3 times per week for 20 minutes for 8 weeks. Participants wore a heart rate monitor while dancing that measured time spent within their target heart rate zone and also estimated caloric expenditure. Body composition was measured via BodPod before and after the 8-week treatment. Participants were asked to fill out a validated Physical Activity Enjoyment Scale (PACES) after each dancing session to measure how much they enjoyed playing the game on a scale of 1-5 (lower scores indicate less enjoyment). When all 14 questions were averaged, 81% of participants scored a 4 or higher out of 5 on the PACES over the 8 weeks indicating consistent high levels of enjoyment. Repeated measures ANOVA showed no significant difference in enjoyment between genders. Males burned an average of 276 calories per 20-minute dance session, while females burned an average of 177 calories. Among all participants, a paired samples t-test showed a significant reduction in body fat (p<0.01) from pre- to post-treatment. Exit interviews with each participant revealed that Dance Dance Revolution was fun yet challenging. Furthermore, almost all participants felt that they benefited in some way from participating in the study and all but 3 indicated their intention to purchase a home version of Dance Dance Revolution to play at their leisure. These results show that playing Dance Dance Revolution 3 times per week for 8 weeks was enjoyable to the participants in this study and had a positive effect on body composition.Keyword(s): dance education, exercise/fitness, technology
