OBJECTIVE: This study determined the intensity of walking exercise prescribed from 70% of peak speed achieved during the incremental shuttle walk test (ISWT) in people with chronic obstructive pulmonary disease and whether a steady-state response was achieved when exercising at this intensity. DESIGN: Each participant performed lung function tests, an incremental cycle test, two ISWTs, and a 10-min continuous walking exercise at 70% peak ISWT speed. Oxygen consumption (V˙O2) was collected using a portable system (Cosmed K4b, Rome, Italy). The V˙O2 from the 10-min walking exercise was compared with V˙O2peak from the better ISWT as a measure of walking exercise intensity. RESULTS: Thirty-four participants completed the study. The mean intensity achieved during the 10-min walking exercise was 76% (11%) V˙O2peak. Steady-state V˙O2 was achieved by minute 5 in the 10-min walking exercise. CONCLUSIONS: Prescription of walking exercise at 70% of the peak ISWT speed provided an intensity appropriate for achieving physiologic training responses. |
