説明

In this study, a linear model was applied in order to predict chronological age on the basis of independent variables such as blood pressure (SBP, DBP), maximal aerobic power (MAP), some measures of physical fitness (FLEX=standing trunk flexion, BALANCE=one foot balance with eye closed, SITUP=situps during 30sec., FAT=estimated percent body fat from skinfolds thickness), and DA=dental age from Sugiyam's estimation.<br>Sixty-seven males (18 to 60 years of age) as subjects participated in this study. The results of this study can be summarized as follows:<br>1) DA showed a fixed contribution for chronological age.<br>2) There was no relationship among dental attrition and physical fitness except SITUP.<br>3) As a result of stepwise regression analysis, the following model was established as optimal: y=36.3+0.424xDA-0.994xSITUP (R2=0.613).<br>4) The stability of this model was confirmed according to the analysis of residuals.<br>5) The model containing all variables is as follows: y=31.3+0.42xDA-1.08xSITUP+0.112xFLEX+0.008xBALANCE+0.036xMAP-0.019xSBP+0.103xDBP-0.094xFAT(R2=0.634)
