The purpose of this study was to prediction of the maximal oxygen uptake by using echocardiography. The sample consists of 18 male athletes and 18 non-athletes. The athletes were long distance and marathon runners, and non-athletes were not participating in any athletic program. Rest echocardiography was used to measure left ventricular variables(LVIDd, LVIDs, PWT, SWT) and maximal matabolic capacity by incremental exhaustion exercise were used to assess maximal oxygen uptake in all subjects. Two-way ANOVA, simple regression analysis, and multiple regression analysis were conducted for the statistical analysis. On the basis of the results analyzed in the study, the conclusion could be drawn as follows : 1. Maximal oxygen uptake in athletes was significantly higher compared to non-athletes, and rest echocardio- graphically measured left ventricular variables(LVIDd, LVIDs, PWT, SWT, LVEDV, LVESV, SV, LVM) were higher in athletes and adults. 2. Using Simple regressions analysis, R-squares to explain maximal oxygen uptake as left ventricular variables were higher in athletes than in non-athletes. 3. By using multiple regression analysis formula for athletes was Y=-1.950720+0.081399 LVIDd-0.263412 PWT+0.444841 SWT(r^2=42.74%) and formula for non-athletes was Y=-6.333901+0.116192 LVIDd-0.443447 SWT(r^2=61.88%). In conclusion, the effects of sustained long-term endurance training caused to changes of the heart size in rest and maximal exercise, and there was closely relationship between heart size and maximal oxygen uptake. Thus echocardiographic study could be applied to sport medicine field as the indirect method to obtain the maximal oxygen uptake.
