November 18, 2006 Civilisation has a problem - the number of obese children (Ages 6 to 11) in America has more than doubled, and the number of obese adolescents (Ages 12 to 19) has more than tripled in the last 30 years with both representing more than 15 percent of their respective age group populations. Whatsmore, the number of overweight children represents another 15 percent and growing, so the recent development of a novel way of incorporating exercise into the health regime of children bears some thought. A British children’s fitness specialist has developed Step2Play, a step exercise machine that links directly to a child’s Playstation. A rate of exercise can be set at the start of the child’s game and then as long as the child maintains a constant rate of exercise as they play their video game, the game’s controller will remain active. If the child stops, the game pauses and the controller stops working. Two players can use different steppers and controllers to play two-player games. There is also another product named CyberBike which is designed for children as young as four and achieves a similar result.
