Abstract:
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.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
