INTRODUCTION
The purpose of this study was to establish the prediction model of ˙VO 2 max using submaximal metabolic responses from the Bruce protocol.
METHODS
The subjects were consisted of 78 male college students. They went through maximal exercise testing with the Bruce protocol, and the metabolic responses were measured in the end of the first and second stage. To determine the predicted model of ˙VO 2 max, multiple regression analysis was applied with enter and stepwise methods.
RESULTS
Analyzing with all variables using enter method, the multiple R of total variable model was 0.796(p<.01), and multicolinearity appeared. The multiple R of 3 minutes model 1 and model 2 were 0.614 and 0.665, and the R of 6 minutes model 1 and model 2 were 0.627 and 0.677(p<.01), however, multicolinearity did not appear. The R amongst the measured ˙V O 2 max and the predicted ˙VO 2 max of 5 model were 0.612~0.796(p<.01). The R amongst 5 model were 0.545~0.927(p<.01), and R between 3 minutes model 1 and model 2, and between 6 minutes model 1 and model 2 were 0.919~0.927(p<.01).
CONCLUSION
The total variable, 3 minutes and 6 minutes model were all verified model to predict ˙VO 2 max, but 3 minutes and 6 minutes are recommended for its convenience. |
