AB  - OBJECTIVES: To evaluate the reliability of the 6-minute walk test (6MWT) in 
      individuals with Down syndrome and explore factors affecting walking distance. 
      DESIGN: Four repeated walk tests in the span of 2 weeks including 2 practice 
      walks. SETTING: All tests were carried out in a 40-meter corridor at a university 
      sport complex. PARTICIPANTS: Adolescents and young adults with Down syndrome 
      (N=55) aged 11 to 26 years. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE: 
      Participants were instructed to walk as far as possible for the duration of 6 
      minutes. Distance walked, heart rate, blood pressure, and perceived exertion were 
      measured across 4 tests (t1, t2, t3, and t4). RESULTS: The walking distances for 
      t1, t2, t3, and t4 averaged 395, 428, 433, and 436 meters, respectively. The 
      6-minute walk distance (6MWD) during t1 and t2 was significantly different from 
      that during t3 and t4 (t(54)=-6.475, P<.001). Repeated analysis of variance 
      showed no significant difference between the distance walked in t3 and t4 
      (433+/-64m vs 436+/-68m) (F(1,54)=2.439, P=.124). Body mass index as well as levels 
      of intellectual disability and physical activity all affected the distance walked 
      to different degrees. CONCLUSIONS: The 6MWT showed good test-retest reliability 
      and increased the walking distance after 2 practice walks, emphasizing the need 
      to account for a learning effect among people with Down syndrome. Reported 6MWD 
      appears lower than that previously reported for individuals without Down 
      syndrome.
