Effects of Karate in Adolescents With Down Syndrome

Not Applicable
Completed
Conditions
Down Syndrome
Interventions
Other: PKSA karate class
Registration Number
NCT03058640
Lead Sponsor
University of Michigan
Brief Summary

This randomized control study will investigate the health outcomes of adolescents with Down Syndrome who participate in a karate class as measured by ALPHA fitness testing and various PROMIS parent proxy questionnaires to assess participants mobility, physical activity, and overall affect.

Detailed Description

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.

GroupInterventionDescription
Karate InterventionPKSA karate classParticipants will be enrolled into PKSA karate classes which includes at least two, standardized 1-hour classes per week for 12 weeks. Participants must attend at LEAST 20/24 classes. Attendance sheets will be signed by parents at each site. Practice at home will also be encouraged. Log sheets will be provided to participants to log their practice
Primary Outcome Measures
NameTimeMethod
PROMIS Parent Proxy Mobility SF v.2.0 -Measure difference between baseline and three months

Parent completed questionnaire including eight questions that gauges parent confidence that their child could perform various mobility related tasks with "no trouble", "a little trouble", "some trouble", "a lot of trouble", or "not able to do"

tricep skin fold testMeasure difference between baseline and three months

Width of skin fold test as measured with calipers as part of Alpha Fitness Test

PROMIS Parent Proxy Physical Activity SF v1.0Measure difference between baseline and three months

Parent completed questionnaire including eight questions that gauges parent's perception of how often their child was able to perform physical activity/exercise over the course of the seven days prior to completing the questionnaire

handgrip strengthMeasure difference between baseline and three months

Squeeze hand dynamometer as hard as possible for seconds. This will be repeated with both hands twice

waist circumferenceMeasure difference between baseline and three months

Simple measure of waist circumference as part of Alpha Fitness Test

BalanceMeasure difference between baseline and three months

Will measure the length of time that participant can stand on one foot (up to 30 seconds)

20m shuttle runMeasure difference between baseline and three months

Participants are to run between 2 lines, 20 m apart in time with an audio signal. The speed of the signal is increased by 0.5 km/h/min. The test finishes when the participant fails to reach the end lines concurrent with audio signals on 2 consecutive occasions (or when participant stops because of fatigue)

standing long jumpMeasure difference between baseline and three months

measure length of distance jumped from static position as part of Alpha Fitness Test

BMIMeasure difference between baseline and three months

Calculation of body mass index by taking participants weight in kg divided by height in meters squared

PROMIS Parent Proxy Positive Affect SF v1.0Measure difference between baseline and three months

Parent completed questionnaire including eight questions that gauges parent's perception of how often their child felt happy, great, cheerful, joyful, in a good mood, refreshed, calm, peaceful

Secondary Outcome Measures
NameTimeMethod
