title: Reproducibility of the incremental shuttle walk test for women with morbid obesity.
abstract: OBJECTIVE
  The incremental shuttle walk test (ISWT) is a valuable tool for the assessment of functional capacity. However, few studies have used the ISWT in individuals with obesity or have determined its reproducibility in this population.
  
  
  OBJECTIVE
  The aim of the present study was to evaluate the reproducibility of the ISWT in women with morbid obesity.
  
  
  METHODS
  Twenty-three women with a body mass index >40 kg/m(2) (mean age: 39.1 ± 7.7) performed the ISWT twice on the same day.
  
  
  RESULTS
  The mean distance traveled was 313.3 ± 100.2 m on the first test and 322.5 ± 98.9 on the second test, with no significant difference between tests. The intraclass correlation coefficient (0.91) indicated excellent reproducibility. Reliability determined through Bland-Altman analysis revealed a small mean difference between tests (-9.2 m).
  
  
  CONCLUSIONS
  The practice of repeating the ISWT appears to be unnecessary for women with morbid obesity, as demonstrated by the excellent reproducibility of the test.
