Table 6. VO2peak prediction models based on peak (P) and submaximal (S) treadmill performance in men and women.
| Equations | Velocity (Range) | Inclination (Range) | R2 | SEE(%) |
|---|---|---|---|---|
| Men | ||||
| VO2peak (P) = 24.24 + (0.599 x inclination) + (3.197 x velocity)–(0.122 x weight)–(0.126 x age) | 9.6 ± 2.1 (3.5–17.0) | 10.3 ± 1.3 (0–15) | 0.75 | 10.5 |
| VO2peak (S) = 35.25 + (1.276 x inclination) + (6.402 x velocity)–(0.196 x weight)–(27.615 x test heart rate/215.336–0.73 x age) | 5.6 ± 1.0 (2.5–12.0) | 9.7 ± 1.3 (0–10) | 0.55 | 14.1 |
| Women | ||||
| VO2peak (P) = 17.21 + (0.582 x inclination) + (3.317 x velocity)–(0.116 x weight)–(0.099 x age) | 7.6 ± 1.7 (2.5–14.0) | 10.7 ± 1.7 (0–16) | 0.72 | 11.5 |
| VO2peak (S) = 23.77 + (1.205 x inclination) + (6.051 x velocity)–(0.16 x weight)–(20.671 x test heart rate/212.497–0.702 x age) | 5.0 ± 0.8 (2.0–8.0) | 9.3 ± 1.8 (0–15) | 0.56 | 14.4 |
