BackgroundIt is not yet completely known whether the 6MWT can be used to prescribe high-intensity exercise for patients with COPD.ObjectiveTo evaluate the ability of the six-minute walk test (6MWT) to prescribe high-intensity exercise for patients with chronic obstructive pulmonary disease (COPD).MethodsLung function, maximal inspiratory strength, symptoms and exercise capacity were evaluated in patients with COPD (n = 27) before and after a 12-week high-intensity exercise program. Criteria for high-intensity training were: 1) â¥75% of the 6MWT average speed; 2) American Thoracic Society/European Respiratory Society (ATS/ERS) criteria (â¥60% of the maximal incremental shuttle walk test speed).ResultsThe 6MWT showed good positive and negative predictive values (0.69 and 0.71, respectively), and accuracy (0.70), good reliability (ICC 0.70 [95%CI 0.45-0.85]) and moderate agreement (k 0.41 [95%CI 0.13-0.67]) with the ATS/ERS criteria.ConclusionThe 6MWT has good predictive ability and accuracy in relation to high-intensity exercise for patients with COPD.
