Effects of Karate in Adolescents With Down Syndrome

Adolescents with Down syndrome suffer from a set of health problems including heart disease, sleep disturbances, and obesity. Their decreased cardiovascular fitness and exercise capacity limits their ability to perform activities of daily living. Exercise interventions in this population of children have been shown to improve muscle strength, balance, and cardiovascular fitness. Prior research has helped better define physical activity barriers in this population which include: requiring parental supervision, lack of accessible programs, seasonal activities and reduced physical skills of the child. Karate is an indoor activity that can be performed at different skill levels without parental involvement. The investigators hypothesize that adolescents with Down syndrome who participate in karate will show improved health outcomes compared to those who did not participate. Furthermore, the investigators hypothesize that the majority of participants will continue the activity outside of the research window. This randomized controlled trial will enroll 30 adolescents with Down syndrome. Participants will be randomly assigned to a 3 month karate program or the control group with no intervention. Measurements are taken at baseline, 3 months, and 6 months using validated ALPHA fitness testing and in addition parents will complete PROMIS questionnaires to assess overall participant's activity level, mobility, and generalized affect. An independent statistician will analyze the groups. This research will help physicians provide adolescents with Down syndrome appropriate recommendations for an individualized physical activity regimen that does not have similar limitations to other exercise programs.
