AB Introduction: The incremental shuttle walking test (ISWT) is used to assess exercise capacity in patients with chronic obstructive pulmonary disease (COPD) and is responsive to pulmonary rehabilitation.Aims: This study was designed to examine the prognostic variables for the ISWT in patients with COPD in pulmonary rehabilitation.Methods: 188 patients (94 men) performed an ISWT before a pulmonary rehabilitation program. Lung function, nutritional status and depression and anxiety symptoms were assessed.Results: The mean (SD) age was 61.1 (10.2) years, FEV1 1.16 (0.54) l, RV/TLC ratio 50.9 (10.4)%, BMI 26.0 (6.6), fat free mass index (FFMI) 18.9 (4.7), depression symptoms (HADS) 6.1 (4.2), anxiety symptoms (HADS) 6.9 (4.2). The ISWT distance was 209.6 (144.7) meters. The total variance explained by the model was 48.2%. R2 change: FEV1 (l) 28.5%, age 7.6%, depression symptoms 7.0%, BMI 3.8% and RV/TLC 1.3%. Sex, FFMI, smoking behavior and anxiety symptoms were not significant.Conclusions: Prognostic variables for the ISWT are both physical (pulmonary and non-pulmonary) and psychological.
