Abstract Subject headings

Background: Prescription of supramaximal HIIT is ideally based on an all-out test. This is, however, not suitable for people with COPD, leading to the use of workloads obtained during a maximal incremental test (CPET), which are less specific for the prescription of supramaximal HIIT. Hence, we evaluated the feasibility of a submaximal anaerobic test, the BCST, that has been used in older adults to prescribe supramaximal HIIT, and the anaerobic cycle capacity of people with COPD vs. matched healthy controls (HC).Methods: Sixteen persons with COPD and HC performed a CPET and a BCST. The BCST is an incremental stepwise test (30s cycling, 30s rest) with two end-of-test criteria: 1) Rating of perceived exertion (RPE) ≥17 or 2) cadence <75 RPM for >5s. End-of-test RPE, symptoms, peak workload (Wpeak) and cardiorespiratory demand were obtained to assess feasibility.Results: A higher Wpeak and lower RPE, symptoms and cardiorespiratory demand were observed in the BCST vs. CPET in both groups (Table1). Absolute BCST Wpeak was significantly lower, while relative BCST Wpeak (%Wpeak CPET) was similar in people with COPD (146±24%) vs. HC (157±17%)(P=0.114).Conclusion: In people with COPD, the BCST is a feasible short-duration submaximal anaerobic test specific for prescribing supramaximal HIIT. Compared to the CPET, it allows for higher workloads with lower cardiorespiratory demand and symptom burden.
