Why the study?
Does corrected peak work rate from an incremental test accurately predict a 6-minute constant work rate for endurance testing in COPD patients and healthy subjects?

High variability in COPD precludes reliable use of predicted WR6 for endurance testing; leaves open validation of individualized protocols in prospective studies.
Does corrected peak work rate from an incremental test accurately predict a 6-minute constant work rate for endurance testing in COPD patients and healthy subjects?
Corrected peak work rate from an incremental test can accurately predict a 6-minute constant work rate for endurance testing in healthy subjects, but is not reliable for COPD patients due to wide variability in tolerated duration.
