     West Virginia-Public schools are using a dance video game to help get students in shape. In these

schools, students are often told to turn off their video games and get some exercise. The schools have

found a new way for their students to work out while playing a new video game. West Virginia is one

of the heaviest states in the country. About half of its fifthgraders are considered to be overweight, and

their parents are worried about that. To get them moving on a healthier path, the state's public schools

are using a video game called "Dance Revolution".

     To use the game, players should stand on a special mat in front of a TV screen. Following arrows

on the screen, players must move their feet to the specific symbols on the mat. Players must move

quickly, touching symbols on the mat at just the right time. With each song, they get more exercise.

     "If we can get children to change their behavior at a young age, they will hopefully grow up to be

healthy and active adults," said Carl Callison of Mountain State Blue Cross, a health care company.

West Virginia is ranked among the top three heaviest states. About a third of West Virginians are

considered to be  obese (肥胖的). Even more are considered to be overweight. Extra weight can lead

to serious health problems such as high blood pressure, diabetes (糖尿病), some cancers, and many

other health issues.

     "One out of three children born in West Virginia today will have diabetes by the time they grow up,"

said Nidia Henderson, a manager for the public employees' insurance program. "That's a terrible thing

and not acceptable."

     All of West Virginia's 157 middle schools are using the video game. School officials hope that all

public schools in the state will use the game within the next three years. However, officials emphasize

that the game is not meant to substitute physical education and health classes. The game will be part of

physical education classes and afterschool programs.
