The purpose of this study is to estimate the health related physical fitness age using principal component analysis in Korean adults. Method of physical fitness age was suggested using correlation analysis, one-way ANOVA and principal component analysis based on physical fitness test in Korean. Six hundred thirty healthy people were volunteered to participate in the study. Physical fitness status were analyzed consider age groups and trend of physical fitness status by age were identified from results of physical fitness test. Minitab R16.0 was used for statistical analysis. Eight items were determined through correlation analysis. Principal component analysis was used for estimation of physical fitness age. The first principal component was interpreted as health related physical fitness age and principal component scores were calculated with a high correlation to age. Multiple regression analysis was used for estimation of the principal component scores. The principal component scores were converted by the mean and standard deviation of chronobiological age. The converted principal component scores were finally revised by using Z-score. Equations for estimation of physical fitness age were developed. Normality test using Ryan-Joiner test and cross validity analysis were used for verification. As a result, the prediction equation based on principal component analysis was found to obtain significant results. From the results, it could be utilized for evaluation of physical fitness test and development of application.
