The purpose of this study is to reveal the physical characteristics of elementary students between Physique Index and Physical Fitness Factor. The result of this study can be used as basic materials to produce the programs geared to step-by-step instructions in actual educational fields, which will vary upon individual difference among the students. This study haypothesize to accomplish its purpose. 1. The difference in Body Weight Ratio(BWR) 2 The difference in Chest Girth Ratio(CGR) 3. The difference in Sitting Height Length Ratio(SHR) 4. The difference in Foot Length Ratio(FLR) The results are as follows: 1. The Characteristice of Physical Performance 1) Power index(27.78土0.89) and in the group of CGR index(47.40土0.39). THe side, female exdurance is at maximum in the group of BWR index(28.15土2.11), CGR index(45.30土1.21), FLR index(14.08土0.04) 2) Male muscular endurance increases as CGR(47.53土0.37), SHR(52.97土0.42), and FLR(14.73土0.22). and the group of physique index BSR(28.15土2.11) is superior to the group of upper of lower indices. On hand, female is at maximum in the group of BWR index(28.15土2.11), CGR(45.40土1.21) SHR(52.06土0.34) and FLR index (14.08土0.04) decrease. 3) Male Cardio - repiratory endurance is at maxmum in the group of BWR index (27.78土2.31), CGR index(52.31土1.49), and FLR(14.73土0.22). Meanwhile, female students is at maximum in the group of BWR index, CGR(45.30土1.21) and FLR(14.08土0.04) index is wuperior to the group of lower indices. 4) Male setting - up exercises is no difference, but SHR(54.76土0.41) of female is superior to the group of upper indices. 5) The balance of all students don\'t discover the physical characteristic of the physique index.
