The purpose of this study was to clarify the validity of 12-min submaximal treadmill walk(TMW)and run(TMR)tests, as indirect measures of cardiorsepiratory endurance, and to develop estimation equations of cardiorespiratory endurance using TMW or TMR performance and some other useful items correlating with cardiorespiratory endurance. Fifty-one young adult men, aged 20〜34 years(22.8±3.6), walked or ran for 12minutes on the treadmill at the intensity corresponding to the level 13 on the Borg's ratings of perceived exertion(RPE13), and performed a maximal incremental exercise test. Mean(±SD)of oxygen uptake corresponding to anaerobic threshold (VO_<2AT>)and maximal oxygen uptake(VO_<2max>)were 42.0±9.0ml/kg/min and 55.9±7.4ml/kg/min, respectively, and mean(±SD)of 12-min walk and run distances were 1221±103m and 2108±269m, respectively. Cardiorespiratory endurance indices(VO_<2AT>and VO_<2max>)significantly correlated with TMW(r=0.49 and 0.48, respectively)and with TMR(r=0.69 and 0.68, respectively). A stepwise multiple regression analysis was applied to determine the estimation wquations of the cardiorespiratory endurance using VO_<2AT>or VO_<2max>as a dependent varible, and TMW or TMR distance, age, resting heart rate(HRrest), and execise frequency in a week as independent variables. The multiple regression equations of VO_<2AT>and VO_<2max>were developed as follows : When TMW distance enterd as an independent variable, VO_<2AT>=20.781X_1+2.298X_3-0.297X_4+31.855(r=0.83, SEE=5.33ml/kg/min) ; VO_<2max>=19.941X_1+1.127X_3-0.208X_4-0.656X_5-0.853X_6+77.884(r=0.88, SEE=3.96ml/kg/min), and when TMR distance entered as an independent variable, VO_<2AT>=15.443X_2+2.158X_3-0.157X_4+14.234(r=0.90, SEE=4.18ml/kg/min) ; VO_<2max>=10.817X_2+1.274X_3-0.1946X_4-0.504X_5+55.234(r=0.89, SEE=3.79ml/kg/min), where X_1 : TMW distance(m), X_2 : TMR distance(m), X_3 : exercise frequency in a week(d/wk), X_4 : HRrest(b/min), X_5 : age(yr)and X_6 : BMI. It is concluded that cardiorespiratory endurance could be better estimated by a combination of submaxmal exercise performance and some easily measurable items correlating with cardiorespiratory endurance such as exercise frequency, circulatory function, chronological age and body composition.
