Table 2 End-exercise values from the three tests: ISWT, ICT and CPET, n = 93.

From: Peak exercise capacity estimated from incremental shuttle walking test in patients with COPD: a methodological study

  ISWT   ICT   CPET  
SpO2, % 87*** (86–88) 90 (89–91) 89 (88–91)
Heart rate, beats/min 115*** (111–118) 131 (127–138) 131 124–134)
Perceived exertion, RPE 15.9*** (15.5–16.3) 17.4 (17.1–17.6) 17.5 (17.2–17.7)

  1. ISWT: incremental shuttle walking test, ICT: incremental cycle test, CPET: semi steady-state cardiopulmonary exercise test, SpO2: oxygen saturation in blood measured by pulsoximeter, RPE: Borg scale for ratings of perceived exertion, CR-10: Borg scale for dyspnoea, VO2 peak: peak oxygen uptake, ***: p < 0.0001 compared to ICT and CPET, †: p < 0.05 compared to ICT. Mean (95% CI).
