Feasibility of activity-promoting video games among obese adolescents and young adults in a clinical setting.

One component of the recent obesity epidemic is the sedentary behaviour of children and adolescents e.g., use of video games consoles. The new generation of video games requires body movements and might thus increase activity. The aim of this study was to evaluate whether such games could have an effect on physical activity in obese adolescents in a clinical setting. Between March and May 2007 activity-promoting video games ("apvg") were offered to all 84 inpatients (aged 13-28 years) registered in a long-term rehabilitation programme on a voluntary base. Reasons for (non-)attendance were assessed. Frequency and duration of use of the activity-promoting video game sessions were documented. Furthermore, heart rate and activity counts during use of "apvg", endurance training, and strength training were measured. Of 84 inpatients, 51 used the "apvg" at least once (69%) over the study period. The median weekly use of the intervention was 27 min during the first week (range 0-182 min), declining to zero (range 0-74 min) in week four. Mean heart rate during the sessions (mean 115 bpm; 95% confidence interval 108-122 bpm) was similar to the heart rate during strength training (106 bpm; 101-112 bpm). The results indicate that the video games could have an impact on the activity of obese adolescents and young adults. However, as the interest in the devices seems to be too low the suitability of them for weight reduction programmes in young people cannot be ensured.
