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.
