Abstract

OBJECTIVE
To explore accuracy and validity of a VO2max prediction equation of the multistage model using by modified Bruce protocol submaximal exercise test in healthy subjects. METHOD: Thirty three healthy subjects (age: 44.0+/-12.9) were recruited. VO2max was measured during treadmill by direct gas analysis from a maximal incremental test. VO2max was then predicted from multistage model equation with age, measured oxygen consumption and heart rate during a maximal incremental treadmill test. And the predicted VO2max values from equation were compared with the measured VO2max values.
RESULTS
The predicted VO2max values and the measured VO2max values were highly correlated (r=0.9, p<0.001). The predicted VO2max values (2,285.3+/-536.0 ml/min) were not significantly different from the measured VO2max values (2,285.5+/-598.5 ml/min).
CONCLUSION
In healthy subjects, the multistage model equation offers a fairly accurate VO2max prediction. Therefore the equation can be used in the estimation of VO2max at modified Bruce protocol in an aerobic exercise program.
