Brief summary

Cycle training intensity for patients with chronic obstructive pulmonary disease (COPD) is normally based on an incremental cycle test (ICT). Such tests are expensive and not readily available to clinicians. The aim of this study is to determine whether cycle training intensity, prescribed from a six minute walk test (6MWT) resulted in a level of exercise (measured by oxygen consumption) known to produce physiological training effects in individuals with COPD.

Inclusion criteria

Diagnosis of mild to severe chronic obstructive pulmonary disease with a ratio of forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) (FEV1/FVC) < 70% with an FEV1 < 80% predicted.
