Measured and Estimated Vo2peak Using ACSM, FRIEND, HF-FRIEND, Oncpeak, and Oncsub
| CPET Measured | ACSM | FRIEND | HF-FRIEND | Oncpeak | Oncsub | |
|---|---|---|---|---|---|---|
| Vo2peak, mL O2·kg−1·min−1 | 21.7 (19.1-25.4) | 29.0 (25.3-33.4) | 26.1 (23.5-29.1) | 21.7 (19.9-23.6) | 22.2 (20.1-24.4) | 22.4 (20.3-24.3) |
| Difference between measured and estimated Vo2peak, mL O2·kg−1·min−1 | 7.0 (4.2-9.9) | 3.9 (2.3-5.9) | −0.2 (−2.1 to 1.5) | 0.02 (−1.7 to 1.5) | −0.2 (−2.3 to 1.9) | |
| Values within 3.5 mL O2·kg−1·min−1 | 70 (18) | 164 (43) | 306 (81) | 325 (86) | 283 (76) |
Values are median (Q1-Q3) or n (%).
ACSM = American College of Sports Medicine; CPET = cardiopulmonary exercise test; FRIEND = Fitness Registry and the Importance of Exercise National Database; HF = heart failure; Oncpeak = oncology peak; Oncsub = oncology submaximal; Q = quartile; Vo2peak = peak oxygen consumption.
