AB  - [Purpose] The current study aimed to investigate factors affecting dyspnea after 
      the 6-minute walk test (6MWT) in idiopathic pulmonary fibrosis (IPF) patients 
      presenting with hypoxemia. [Subjects and Methods] The subjects were IPF 
      out-patients with stable symptoms whose percutaneous arterial oxygen saturation 
      fell to 88% during the 6MWT test. Quadriceps force, 6-minute walk distance 
      (6MWD), dyspnea after the 6MWT, and leg fatigue (LF) were evaluated as 
      exercise-related variables. [Results] The subjects were 14 patients (mean age 
      73.6 +/- 6.3 years) classed based on the modified Medical Research Council dyspnea 
      scale as 0 for 2 patients, 1 for 6 patients, and 2 for 6 patients, indicating 
      that the patients were comparatively mild cases. Mean 6MWD was 408.9 +/- 102.4 m, 
      and dyspnea after the 6MWT and LF were 3.0 +/- 1.4 and 1.5 +/- 1.5, respectively. 
      Dyspnea after the 6MWT was correlated with vital capacity (VC), forced vital 
      capacity, and LF. Stepwise multiple regression analysis identified VC and LF as 
      factors significantly affecting dyspnea after the 6MWT. [Conclusion] The results 
      of this study demonstrated that it is necessary to evaluate both pulmonary 
      function and LF in IPF patients presenting with exercise-induced hypoxemia and 
      exertional dyspnea.
