AB  - OBJECTIVES: To investigate if the distance covered in the Six-Minute Walk Test 
      (6MWT) and in the Incremental Shuttle Walk Test (ISWT) is most strongly explained 
      by walking capacity or cardiorespiratory fitness (CRF) measures in individuals 
      after chronic stroke. MATERIALS AND METHODS: This is a cross-sectional study. 
      Individuals after chronic stroke aged at least 20 years old and able to walk at 
      least 10 minutes independently were included. The distance covered (meters) in 
      the 6 MWT and ISWT (dependent variables), comfortable and fast gait speed 
      obtained by the 10 m walk test (10 mWT) (walking capacity measures; independent 
      variables) and peak oxygen consumption (VO(2peak); CRF measure; independent 
      variable) (ml.kg(-1).min(-1)) obtained by the cardiopulmonary exercise test 
      (CPET) were obtained. Linear regression analyses were performed (alpha = 5%). 
      RESULTS: Fifty individuals (mean age of 55+/-12 years and mean time after stroke of 
      67+/-74 months) were included. Comfortable and fast gait speeds were the variables 
      that most strongly explained the distance covered in the field tests: 6MWT 
      (R(2) = 0.614, beta = 0.784, p < 0.001 and R(2) = 0.615, beta = 0.778, p < 0.001, 
      respectively) and ISWT (R(2) = 0.450, beta = 0.671, p < 0.001 and R(2) = 0.456, 
      beta = 0.746, p < 0.001, respectively). On the other hand, for the VO(2peak), the 
      following models were generated: 6MWT (R(2) = 0.280, beta = 0.530, p < 0.001) and ISWT 
      (R(2) = 0.154, beta = 0.393, p = 0.005)(.) CONCLUSIONS: The distance covered in the 
      field tests (6MWT and ISWT) is more suitable to support inferences about the 
      walking capacity than about the CRF of individuals after chronic stroke.
