| Contributing to the child obesity epidemic is a decline in daily physical activity. Given the importance of physical activity in preventing childhood obesity and the growing popularity of video games, it is necessary to find ways to link technology and physical activity. Kinect is an interactive video game that enables players to use their own body as a controller. This study was the first to investigate the physiological benefits of Kinect. The effect of reinforcing treatment attendance and weekly exercise goals on heart rate and step count was also investigated. Using a hybrid multiple baseline reversal design, physiological data were recorded for five overweight/obese and two non-overweight/obese participants (ages 7 to 11) during two to three baseline and two intervention periods. Heart rate averages and step amounts were assessed for approximately one hour, three times a week, over four to six consecutive weeks. Measures of heart rate and step amounts during Kinect play mimicked intensities achieved in traditional physical activity. Overall, heart rate and step amounts were higher during Kinect play relative to baseline periods. Reinforcement of attendance and time spent playing Kinect did not appear to result in longer Kinect play, but further investigation is warranted. The built-in reinforcing mechanisms of Kinect may increase the likelihood that obese/overweight children will engage in physical activity for longer periods of time. Therefore, Kinect may have the potential for improving physical activity among children who struggle with weight and may be a viable component of weight related treatment plans. |
