Procedures and Protocol: After interested participants contact the researcher and are determined to be eligible to participate in the study, families will be visited on site for fitness testing and parents will be asked to complete a brief demographics, physical activity, and quality of life questionnaire while children are asked to complete a brief physical activity and quality of life questionnaire. We will employ a certified exercise physiologist to ensure consistency of the testing. The measurement team will be blind to the treatment conditions of the participants. The family will then be randomized into one of the two conditions. In the standard group, participants will play the games against computer-controlled opponents. In the augmented exergames intervention group, participants will play together, and will be able to talk with each other via a voice over IP link. A Facebook page will be developed allowing the publication of game news, and allowing players to communicate about the game, such as arranging play sessions. For security, only children or parents enrolled in the trail will be permitted to play the game online. The game will be available for play during scheduled times, with separate times for children and for adults.
