Matthews et al developed an equation for predicting cardiorespiratory fitness of adults based on body measurements and self-reported physical activity. The authors are from the University of Massachusetts.
Patients: adults 19 to 79 years of age
Parameters:
(1) age in years
(2) gender (male 1, female 0)
(3) physical activity status (PAS)
(4) height in meters
(5) body mass in kilograms
The Physical Activity Status (PAS) ranges from 0 (avoids any physical activity) to 7 (heavy physical exertion).
predicted maximal oxygen uptake in mL per kg per minute =
= (0.133 * (age in years)) – (0.005 * ((age in years)^2)) + (11.403 * (points for gender)) + (1.463 * (PAS points)) + (9.17 * (height in meters)) – (0.254 * (body mass in kilograms)) + 34.142
