Abstract

INTRODUCTION
The purpose of this study was to develop the prediction model of V˙O 2 max using submaximal metabolic responses from the Bruce protocol, and distance running record, and to compare and analyse the validity of these prediction models.
METHOD
The subjects were consisted of 214 male 20s years old males. They were participated maximal exercise testing with Bruce protocol, and the metabolic responses were measured in the end of the first(3 minute), second stage(6 minute), and 1,200m running record. Measurement items were V˙ O 2 (ml/kg/min), V˙CO 2 (ml/kg/min), V˙E(L/min), HR(bpm) of 3 and 6 minute, time to HR 150bpm and 170bpm, HR difference between Bruce protocol 6 and 3 minute, 1,200m running record. To determine the predicted model of V˙O 2 max, multiple regression analysis were applied with enter and stepwise methods.
RESULT
Analyzing with all variables using enter method, the multiple R of total variable model was 0.671(p<.01), SEE was 6.60 ml/kg/min, CV was 15.6 %, but multicolinearity appeared. The multiple R of 3 minutes model 1 and model 2 were 0.437 and 0.472, SEE was 6.94 and 6.82 ml/kg/min, CV was 16.4 and 16.1%, and multicolinearity did not appeared. The multiple R of 6 minutes model 1 and model 2 were 0.571 and 0.585, SEE was 6.35 and 6.29 ml/kg/min, CV was 15.0 and 14.8%, and multicolinearity did not appeared. The R of HR150 and HR170 model were 0.268 and 0.274, SEE were 7.58~8.10 ml/kg/min, CV were 17.9~19.1%. The R of 1,200m running model was 0.270, SEE was 7.11 ml/kg/min, CV were 16.8%.
CONCLUSION
With considering usefulness and convenience through the validity of these prediction models, the prediction model of V˙O 2 max recommended 6 and 3 minute model, HR170 model, 1,200m running model, HR150 model, and 6 minute HR-3 minute HR model by tunes.
