Access to TV contingent on physical activity: effects on reducing TV-viewing and body-weight.
One child was recruited for a study assessing the effectiveness of a device aimed at reducing excessive television viewing and increasing exercising. The device was comprised of a control box which attaches to the electrical cord of a television set, and two sensors which attached to the wheel and corresponding wheel rim of a stationary bicycle. The child in this study was watching an excessive amount of TV (averaging over 4 hours per day), and she had a weight problem. An ABAB design was used in the study. After collecting baseline data, the child was required to ride a bicycle for 60 minutes to watch 60 minutes of TV, and this program successfully reduced TV viewing. Reductions in TV viewing and weight loss were found at a follow-up.
