Relative intensity (%HRR and %VO2R) for a same Pext (W) on IE and DE and classification of exercise intensity on IE (mean ± SD).
| rpm | Pext (W) | %HRR | %VO2R | Intensity | ||
|---|---|---|---|---|---|---|
| IE | DE | IE | DE | |||
| 50 | 50 | 21.2 ± 1.4 | 21.8 ± 1.9 | 21.3 ± 1.7 | 23.1 ± 1.1 | Very light |
| 60 | 75 | 35.3 ± 1.7 | 38.2 ± 1.7 | 38.5 ± 2.5 | 32.0 ± 1.3 | Light |
| 70 | 125 | 56.7 ± 2.1 | 57.6 ± 1.8 | 59.4 ± 3.3 | 50.9 ± 1.6 | Moderate |
| 80 | 200 | 85.3 ± 2.1 | 81.7 ± 1.9 | 85.2 ± 2.3 | 80.2 ± 2.5 | Vigorous |
| 90 | 300 | 98.4 ± 3.4 | 97.5 ± 3.9 | 96.7 ± 6.7 | 97.4 ± 4.7 | Near-maximal |
Note: very light < 30; light: 30–39; moderate: 40–59; vigorous: 60–89; near-maximal ≥ 90. Classification of exercise intensity adapted from ACSM.1
Abbreviations: %HRR = percentage of heart rate reserve; %VO2R = percentage of oxygen uptake reserve; DE = dryland ergocycle; IE = immersible ergocycle; Pext = external power output; rpm = revolutions per minute.
