Background: Youth in the United States have low levels of cardiorespiratory fitness, a risk factor for childhood obesity. Lower levels of physical fitness for black and Hispanic youth contribute to health disparities. In this feasibility study, we examined active video games (AVGs) as a tool to improve fitness and attitudes toward physical activity during early adolescence. Method: A 6-week AVG program took place in a youth development program in a high-poverty neighborhood in New York City. Youth aged 10 to 15 years (50% overweight or obese) participated in 2 fitness tests and completed surveys that captured barriers to physical activity pre- and postintervention. Each week, participants played Wii Fit games for 30 minutes. Results: Participants improved the number of sit-ups and step-ups they completed from pre- to postintervention (p < 0.05). Participants also increased their self-efficacy, intention to exercise and perceived social support to exercise (p < 0.05). Youth reported a high level of enjoyment and perceived Wii Fit as ways to increase physical fitness and increase their physical activity. Conclusion: AVGs may be a viable alternative exercise program to increase physical activity for black and Hispanic youth living in poverty-impacted neighborhoods.
