Although video games are often associated with sedentary behaviors, active gaming is a new genre that requires children to become physically active while playing the games. In this study six fifth grade students' experiences participating in active gaming in eight-week physical education classes were explored. Qualitative methods of interviews, journal entries, and observational field notes were employed. Analysis of data reveals a major theme of students' "Persistence to Game" (P[subscript 2]G) when participating in active gaming during physical education, and seven subthemes associated with the major theme were identified. Both Play theory and Flow theory were used to explain the major theme and seven subthemes that emerged. The findings of this study suggest that active gaming can be used in 21st century physical education class to increase children's physical activity levels. (Contains 3 figures.)
