| ABSTRACT |
|
The purpose of this study was to develop the prediction model of V̇O2max using submaximal metabolic responses from the Bruce protocol, HR responses at several stages and 1,200 m running record, and to compare and analyse the validity of these prediction models. The subjects were consisted of 255 male(133 male for 1,200 m running). 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 1,200 m running record. Measurement items were V̇O2(㎖/㎏/min), V̇CO2(㎖/㎏/min), V̇E(L/min), HR(bpm) of 3 and 6 minute, time to HR 150 bpm and 170 bpm, HR difference between Bruce protocol 6 and 3 minute, 1,200 m running record. Analyzing with all variables using enter method, the multiple R of total variable model was 0.642(p<.01), SEE was 4.38 ㎖/㎏/min, CV was 10.8 %, but multicolinearity was appeared. The multiple R of 3 minutes model 1 and model 2 were 0.341 and 0.461, SEE was 6.05 and 5.72 ㎖/㎏/min, CV was 14.9 and 14.1%, and multicolinearity did not appeared. The multiple R of 6 minutes model 1 and model 2 were 0.350 and 0.456, SEE was 6.03 and 5.74 ㎖/㎏/min, CV was 14.9 and 14.2%, and multicolinearity did not appeared. The R of HR 170 and HR 170 model were 0.151 and 0.154, SEE were 6.36~6.37 ㎖/㎏/min, CV were 15.7%. The R of 1,200 m running model was 0.444, SEE was 4.82 ㎖/㎏/min, CV were 11.9%. In conclusion,with considering usefulness and convenience through the validity of these prediction models, the prediction model of V̇O2max recommended 6 and 3 minute model, and the validity of HR model and 1,200 m running model were moderately low. |
