Summary
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.
